DC Motor Drives. Definition: The DC motor drive is a type of amplifier or power modulator that integrate between the controller and a DC motor. It takes the low current and then converts it into a high current which is appropriate for the motor. The DC motor drive also provides the high current torque, 400 % more than the rated continuous torque.

Consumption of a good motor A DC treadmill motor in good standing should absorb no more than 1.5-1.8 A when connected to the treadmill belt with no load (nobody on the treadmill). A motor tested on the bench (with no drive belt connected) should absorb about half (.4 to max .9A).
Such construction will simplify wind turbine building and lower the noise produced by the windmill. Step motor produces stable voltage even on low rpm (200 rpm), which is a great advantage comparing to DC alternators/motors. DC motors require at least 10 to 15 times higher rpm to achieve similar power output.
