Question

What is the Draw on a Golf Cart Motor?

Answer and Explanation

The electrical draw on a golf cart motor, often measured in amps, isn't a fixed number. It fluctuates depending on several factors, primarily the load on the motor. When a golf cart is accelerating, climbing a hill, or carrying heavy cargo, the motor draws more current (amps) to produce the necessary torque.

Typically, golf cart motors can draw anywhere from a few amps at idle to upwards of 100 amps or even more under heavy load. Factors influencing the draw include:

  • Speed and Acceleration: Higher speeds and rapid acceleration demand more power, resulting in a higher amp draw.
  • Incline and Terrain: Going uphill or traversing uneven terrain increases the motor's workload and, consequently, the amp draw.
  • Load: The weight of passengers and cargo directly impacts the motor's demand for power.
  • Motor Type and Condition: Different motor designs and the motor's overall condition will affect its efficiency and draw. An older or poorly maintained motor may draw more current.
  • Battery Voltage: Although amps are the main factor here, battery voltage plays a role. Lower voltage can sometimes cause higher amp draw to maintain performance.

Understanding the draw is essential for assessing battery life and choosing the appropriate battery and controller system for a golf cart. Using an ammeter, you can measure the draw under various conditions to understand your cart's power consumption pattern.
