Most industrial ac motors are three-phase designs that are at least 60% more efficient than single-phase motors, with excellent speed-control potential. In controlling this range of motors, your ...

There are several reasons to use a three-phase inverter to run a single-phase induction motor, including isolation from variable power grids, reduction of peak currents and elimination of the starting ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

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 ...

Allegro MicroSystems, Inc. announces a new high voltage three-phase motor driver family in a small package that minimizes board space and expands the use of inverter technology (variable speed control ...

Allegro MicroSystems, Inc. adds several new devices to their existing Inverter Power Module (IPM) portfolio. The SCM1240M family provides a robust, highly-integrated solution for optimally controlling ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
