A squirrel cage induction motor must sense two or more electric phases to cause the magnetic field to start spinning, thus turning the motor’s rotor and shaft. Once the motor starts, the interaction ...

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 ...

Correctly installing capacitors at the terminals of your motors can lower reactive power requirements and increase system power factor. Induction motors are the primary source of rotary power in the ...

Most of these motors use a centrifugal switch to disconnect the start capacitor from the start winding circuit at the time the motor will reach around 70 to 80 of its run speed. The ...

The diameters of the new series range from 25 to 40 mm at insertion heights of 58 to 120 mm. The new types are designed for rated voltages of 400 and 450 V AC and cover a capacitance range from 2 to ...

The QPC series of AC motor run capacitors feature locking push-wire terminals that speed installation and eliminate soldering. A metal mounting bracket also speeds assembly. Standard values range from ...

BELOIT, Wis. - Regal-Beloit Corp. announced that it has signed a definitive agreement with General Electric Co. under which Regal-Beloit will acquire the HVACR motors and capacitors operations of GE ...

Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...
