A motor control IC is a convenient way to implement custom motor drive algorithms such as the single-phase induction motor (SPIM) control. A generalized control algorithm, implemented and tested in an ...

Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

The dominant control method for these motors relies on pulse-width-modulation (PWM) techniques to switch an inverter bridge that delivers the electrical output power. Motor-control designers already ...

Inverters used to control a motor’s speed or torque — also known as variable frequency drives (VFDs) or adjustable speed drives — can induce unwanted motor shaft voltages that cause premature motor ...

Inverter gate driver optocouplers are ideally suited for IGBT and MOSFET applications for variable speed motor drives. Their high output peak currents, coupled with high voltage safety standards ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...
