The two windings are out of phase by 45 to 90 degrees which gives the motor a boost on startup. Unlike the capacitor-start-induction-run motor that used a capacitor, this motor makes use of a ...

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 ...

Efficiency standards were once confined to integral horsepower motors but may soon apply to small motors and make certain kinds impractical to manufacture. Today, the electric motors that are of most ...

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 ...

For safe, long-term use of a compressor, the motor winding temperature must be kept below certain limits, in all conditions in which the appliance may operate. For example, compressors from AC ...

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 ...
