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 ...

Appliance makers are always looking for quieter, moreefficient motors. Although they've been using singlephase, single-winding, twopole synchronous motors for decades, such motors can be inefficient ...

While troubleshooting the cause of a motor failure, you discovered a phase imbalance of 5% at the motor leads. Now what? You need to find and fix the cause, but where do you start? Begin by ...

The first installment of this two-part series focused on debugging brushed-DC motor systems. Now the second installment will share some tips for stepper motor systems and provide general bench testing ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...
