Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

An optimal design and control technology of a wheel motor for electric passenger cars is proposed. The objectives are to maximize the driving torque, efficiency, rated speed, and to minimize weight of ...

Fun fact: Dynometers do not measure horsepower, they measure torque. That torque figure, when multiplied by the rpm it is measured at, and then divided by 5,252, is essentially how a dyno derives a ...
