MOSFET is often used in motor drivers of different types of motors. This article will show you the functional features of a variety of MOSFETs introduced by ON Semiconductor.
Different motor specifications with different powers of MOSFETs
By using power switching components such as MOSFET to turn on or off MOSFET, the voltage applied to the motor winding can be adjusted to realize the control of motor speed or rotating shaft position. Such power switching components can be used for the drive control of DC brush motor, DC brushless motor, stepper motor, switched reluctance motor, and AC induction motor.
Even if the types of motors are different, the function of the drive circuit is to provide controllable voltage and current to motor windings. The voltage and current values will vary depending on the type and size of the motor used. When selecting MOSFETs, the power required to drive the motor must be confirmed before selecting the appropriate power switching component. As the voltage and current ratings of different motor types are different, the drive devices with specific ratings should be selected according to the requirements of the application and design objectives.
