Electric motor horsepower conversion to amps
Abstract:
One of the major advantages of reducing the mechanical horsepower would be the effect on the electrical requirements. The electric motor was determined to be capable of being efficient at a reduced load which in turn would require less electrical current draw by the motor. The original design of the compressor called for 440 V delivered at 90.3 A.

Figure 6 represents the amount of EV motor horsepower required to propel a 3500lb EV vehicle at various speeds. At 40 mph the required motor horsepower is approximately 17 ½ and at 60 mph 59hp is required. The typical EV motors readily available for EV project are 30 to 40hp motors. There are however a few exceptions.

Unfortunately all 5 HP compressor motors are not equal in actual power either, to judge the true horsepower the easiest way is to look at the amperage of the motor. Electric motors are not efficient, most have a rating of about 50% due to factors such as heat and friction and some may be …

As with any energy conversion device, the DC shunt motor is not 100% efficient. Not all of the electric energy supplied to the motor is converted into useful work (mechanical power). The difference between electrical power supplied and mechanical power available at the shaft is lost in the form of heat inside the motor.

Objective: To understand how an electric motor converts electrical energy to mechanical energy. SWBAT understand that electric motors convert electrical energy to mechanical energy. SWBAT identify the parts of an electric motor. SWBAT define torque as Force x Radius. SWBAT understand that motors have a maximum torque and how this can be determined.

Used in a self-powered electric vehicle, a 50-pound, 50-horsepower electric motor is equivalent to a 250-horsepower gasoline-fueled engine. The perm-mag motor’s inventor, Ronald Brandt, has successfully demonstrated a 10-pound, 10-horsepower prototype.
