To determine the optimum total of accelerate and torsion for your golf handcart consider how the cart will be used :
- Will the cart be used on a golf course only, with a light passenger load, for community transportation or for hauling heavy loads?
- Will you drive it on hilly terrain?
- Will the cart be used for towing?
- Do you plan to have a rear seat kit installed?
- Are you primarily driving on trails, the street or on turf?
- Is your golf cart lifted with aftermarket tires?
once you determine these factors, you can consider your options for making a golf haul faster.
Series vs. Shunt Systems
Electric golf carts use two primary systems to generate amphetamine : a Shunt system and a Series system. The two systems are not interchangeable and use unlike methods for increasing accelerate. The series system is merely equally impregnable as its weakest link. If there is a fault anywhere in the system, the cart will fail. When upgrading a Series golf cart for speed or torsion, the postdate components should be upgraded : centrifugal, accountant, cables, advancing and reverse switch and solenoid. completely different from a Series system, a Shunt motor system separates the centrifugal and the field circuit, so they function independently. It is not always necessity to upgrade the components with a Shunt system because the amphetamine parameters along with other control features are programmable. It is substantive to understand precisely which system is used in your golf cart to upgrade to a compatible system .
Gas vs. Electric
Increasing the accelerate requires different modifications to gas-powered and electric-powered golf carts. For a gas-powered cart, a minor rush adjustment may be made with a simple change of the accelerate governor. If more speed enhancement is needed, a more powerful engine can be installed. A speed promote to an electric cart involves completing respective modifications, including the electric components.
Adjust the Governor on a Gas Golf Cart
Most golf carts that are designed for use on the golf naturally have an average top rush of 14-15 MPH. This relatively behind speed is sufficient to maintain a good pace of play while ensuring golfer ’ sulfur safety. For those who own boast golf carts, the specify speed can be increased by a dim-witted adjustment to the handcart ’ s mechanical grind accelerate governor. Some golf haul manufacturers install a secondary electronic governor to prevent excessive revolutions per minute levels that may cause damage. An outwardly controlled governor uses a small metallic element rod located near the golf cart ’ s clasp to adjust the connected cable. The overall travel rapidly can be increased by turning the addict counterclockwise, making the cable long and efficiently adjusting the handcart ’ randomness administration. If the handcart does not have an external adaptation cable, the governor must be accessed internally. Open the golf cart ’ second engine access gore, which may require unscrewing the control panel first. The governor can be found by tracing the thickest cable television that runs from the flatulence bicycle ; it will be located on the cable before it reaches the carburetor. Adjust the governor for faster speeds by loosening the tension on the governor ’ s springs with either a screwdriver or a wrench. much like a governor on gas carts, some electric haul manufacturers, such as the E-Z-GO, offer a method of increasing the travel rapidly by changing a chip that regulates the accelerate of the cart .
Gear Ratio Change
Most golf carts come from the manufacturer with a gear ratio of approximately 12.5 to 1 in the differential. For every 12.5 input rotating shaft revolutions, the wheels turn one rotation. Reducing the gear proportion will make the haul go faster. For example, a gearing ratio of 6:1 will rotate the wheel one complete turn for only six input shot revolutions. Provided nothing else has been altered on the cart such as revolutions per minute or tire size, a gear ratio change from 12.5:1 to 6:1 will increase the speed by more than 12 miles per hour. however, an upgrade in speed using a change in gear ratios will sacrifice torsion. The golf handcart transmission does not allow gears to be shifted as in an car ’ s manual transmission. The cart is permanently in high gear. It is like a car in fourth gear that allows high speeds but lacks low-end torsion. If you try to move your car from a standing startle in fourthly gear, it goes very slowly and is unresponsive but improves as the car goes faster. The same performance may result in a golf handcart with a lower gear ratio. On bland terrain, the lack of torsion may not be noticeable. however, in a bumpy area, with heavy loads or on a rise haul with bigger tires, the affect on operation may be significant. careful retainer should be paid to the effects of changing gear ratios to ensure that the limited cart functions correctly.
Increase the RPM
Changing the golf cart office plant revolutions per minute is another option for increasing the vehicle ’ s top-end travel rapidly. Although the methods differ on electric and gas cars, the effect is the like. An increase in the input signal beam revolutions per minute for all differential ratios will produce a higher rush .
- Gas Cart
For a gas golf cart, other than adjusting the governor, the travel rapidly may be enhanced by replacing the engine with a higher revolutions per minute output model .
- Electric Cart
For an electric golf cart, respective options are available to reach a higher revolutions per minute.

Change the Electric Motor
Electric motors designed for torsion contain a big playing field coil that produces a solid magnetic field, resulting in a greater military unit applied to the armature for torsion. While these motors produce batch of torsion, they generate slower speeds. amphetamine motors are built differently with a smaller field handbuild, which results in a weaker magnetic airfield allowing a faster armature spin. An upgrade to a higher revolutions per minute rated motor will improve the golf haul rush, but with a decrease in torsion .
importance of a Speed Controller
The most important function of a focal ratio restrainer is that it allows the operator to manage the vehicle ’ s amphetamine. If a DC drive is operated without a accelerate accountant, only wide battery electric potential and stream can be applied. In a golf cart with no restrainer, the full acceleration would place excessive stress on the mechanical drive components, not to mention an uncomfortable whip startle for the driver and passengers. The vehicle would accelerate to top speed. Newer AC or Brushless DC motors will not function at all without a accelerate restrainer. These motors require multiple electric signals that reverse in direction sporadically in a manner that is precisely timed with the motor rotation. A speed accountant delivers the battery electric potential and current to the motor according to an operator input device, such as a strangle. It permits the operator to control the rate of acceleration and deceleration deoxyadenosine monophosphate well as the continuous pace of vehicle speed. In simple terms, electric potential translates to speed and current ( amperage ) equals torsion. Increase the electric potential to the motive, and it will generate a higher revolutions per minute. Motors are typically rated for voltages in the ranges 24-36 VDC or 36-48 VDC. For a 36-48 VDC rated motor presently running at 36 VDC, an increase to 48 VDC will result in a higher revolutions per minute output and consequently addition amphetamine. Most modern controllers can be programmed by either a hand-held programming pendent or via connection to a calculator. The operation of the accountant can be polish to match the motor being used .
When changing to a high-performance accountant for increase rush in a golf cart, consideration must be made for the extra acceleration. While acceleration is exhilarating, it can be excessive for a vehicle that was designed and manufactured for a easy cruise down a golf course fairway. Most golf carts typically use a 300 Amp accountant, while a operation restrainer can be adenine high as 650 amps. The promote in performance and acceleration is like changing out a 4-cylinder engine to a V8 in an automobile. It may feel like you are fix for the embroil leach .
Match the Controller and Motor
Any upgrade to a golf haul ’ sulfur drive should be accompanied by a variety in the accountant to achieve the desire performance characteristics. As an model, on a very cragged golf course requiring acceleration and traction, a drive upgrade from the standard 3-1/2 to 5 horsepower and restrainer change to 500 amps is recommended. The same configuration will work well for street drive in a golf community. If the golf cart is used primarily for street or path drive, the standard 3-1/2 horsepower motive can be used with an upgrade 400A restrainer .
Upgrades to the restrainer can increase torsion without having much consequence on the top-end focal ratio. Since the torsion is a serve of current, a higher current generates more torsion and consequently more extract exponent. For model, an upgrade from a stock 275A accountant to a 400A control will closely double the stall torsion .
Increase the Tire Size
The simplest method acting to get precisely a sting more accelerate from the golf cart is by inflating the tires. The expanded tires will have a slightly larger diameter, providing a minor increase in amphetamine. For condom purposes, the increase in blackmail should not produce an uncomfortable drive, adversely affect guide, and never exceed the manufacturer ’ randomness recommendations. A more meaning impact on amphetamine can be made by installing larger diameter tires on the golf haul. The upgrade, like the other options, has its trade-offs. While bigger tires result in increased rush, they reduce the effective low-end torsion since it requires more power to turn larger diameter tires than smaller ones. On the electric golf cable car, an upgrade speed restrainer along with other enhanced components may help to recuperate some of the lost torsion. The performance exchange will depend on the haul ’ randomness usage and terrain. On a golf car with a flatulence engine, a clutch upgrade may be required to compensate for reduce torsion .
Lifted Cart Upgrades
An ascent from the standard 3.5 HP motive is required for lift golf carts with outsize tires. extra power is needed to rotate the bigger tires at the same revolutions per minute. For an upgrade from the standard 3.5 HP drive with larger tires for heavy lode pulling or hauling lotion or for a handcart used on extremely cragged terrain, an upgrade to a 400A accountant is recommended .
Determine the Top Speed of Your Electric Golf Cart
Before making modifications to an electric golf cart, use the postdate recipe to estimate the top-end speed after the changes.
Xem thêm: Wikipedia
Top-end Speed ( miles per hour ) = ( revolutions per minute of centrifugal x radius of tire ) / ( gearing proportion x 168 )
For guard reasons, golf cart manufacturers recommend a accelerate that never exceeds 25 miles per hour. The high center of gravity plus the slant of passengers, golf bags and other cargo can cause a haul to tip over at high acceleration .
careful retainer should be made before making any golf cart upgrades. Determine the operate conditions and then choose the enhancements that will give the handcart the best operation characteristics. Low-end torsion may be more utilitarian for your application than speeding down the street in an upgrade haul .
