• Performance based on Stock Controller comparison.

• All motors can be used at 36 / 48 volts.

Vehicle performance specs are compared to the standard factory performance. Several factors can effect the performance. Some are battery conditions; tire size, tread type and air pressure; and varying environmental conditions. Standard factory speeds normally run about 14 MPH!!! All vehicle speeds noted are calculated on flat ground. Adding Larger tires normally adds between 2-3 MPH. If you are unsure of how to use the above chart, please call (315) 701-0635. If you do not see the performance you require, please call. We often are capable of making non-standard motors through our engineering department.

• What it is: The maximum horsepower the motor can produce for a short duration (usually seconds to a few minutes).
• Use Case: Useful during acceleration, startup, or when extra torque is temporarily needed (like in go- karts, e-bikes, or heavy-duty machinery).
• Limitation: Not sustainable for long periods—pushing the motor at peak power for too long can overheat or damage it.

• What it is: The maximum horsepower the motor can safely produce continuously without overheating or degrading performance.
• Use Case: This is the reliable, everyday power the motor can deliver during extended operation—important for systems that run for long periods.
• Rated Conditions: Usually based on ambient temperature, cooling, and duty cycle assumptions (e.g., 40°C ambient, proper ventilation).

Think of it like your own strength:

• Peak HP is like lifting something heavy for a few seconds.
• Continuous HP is what you can lift repeatedly or hold for an hour without tiring or hurting yourself.

Voltage Information

Most golf carts operate on either a 36V or 48V system, affecting their power, torque, and speed. If you don't need maximum performance, a 36V system offers good performance at a lower cost. For maximum performance, a 48V system is recommended. Most D&D golf cart motors are compatible with both voltages.

Torque Information

Motor Types:

• High Speed Motor: Ideal for achieving maximum speed, but not recommended for:
  • Hilly terrains
  • Towing trailers or boats
  • Carrying more than 3 passengers
  • Carts equipped with lift kits or oversized tires
• High Torque Motor: Perfectly suited for demanding tasks, providing robust performance.
• Speed and Torque Motor: A versatile option for a variety of applications, making it an excellent choice if you’re unsure of your needs.

Caution:

Using a High Speed motor inappropriately could cause permanent damage.
