The motor can be driven in half step, normal and wawe drive modes and on-chip PWM chopper circuits permit switch-mode control of the current in the windings. TWO PHASE BIPOLAR STEPPER MOTOR CONTROL CIRCUIT This circuit drives bipolar stepper motors with … Retrieve Document

Wikipedia Boost Converter – Wikipedia, The Free Encyclopedia
The NHW20 model Toyota Prius HEV uses a 500 V motor. Without a boost converter, the Prius would need nearly 417 cells to power the motor. However, a Prius actually uses only 168 cells and boosts the battery voltage from 202 V to 500 V. Boost converters also power devices at smaller scale applications … Read Article

Wikipedia RepRap Project – Wikipedia, The Free Encyclopedia
Early extruders for the RepRap used a geared DC motor driving a screw pressed tightly against plastic filament, forcing However, due to their large inertia, DC motors cannot quickly start or stop, and are therefore difficult to control with precision. Therefore, more recent extruders use stepper … Read Article
