The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

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 ...

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 ...

A dc motor driving an ac alternator was used to simulate an asynchronous wind electric generator. The output was used to drive a commercial air conditioning unit containing a hermetically sealed three ...

Although an increasing interest and use of Permanent Magnet Synchronous Motors (PMSM) can be observed during the last decade, the standard 3-phase Induction Motor (IM) is still the most widely used ...

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 ...

Variable frequency drives convert ac power to dc and then reshape that current to control ac motors. All types control speed by varying current frequency, but one subtype — flux vector drives — uses ...

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...
