2 AC Motor Drive VISHAY components used for Motor Drives can include: Power MOSFETS High-Power Modules Diodes and Rectifiers Capacitors Resistors Thermistors Visible LEDs Optical Isolators Inductors / EMI Filters Shunt Resistors ESD Protection Devices LDOs Communications Interface ICs Application Overview A motor can be a simple induction machine that rotates with the connection of a simple AC voltage. In applications that require more precise control of speed, torque, or positioning, it is more common to use a 3-phase motor. In order to control this type of motor, signals must be generated that cause the motor to spin properly, using feedback to close the loop and regulate the desired parameters. page 2
