A hermetic compressor motor relay is an automatic switching device designed to disconnect the motor start winding after the motor has come up to running…
The permanent split-capacitor (PSC) motor is used in compressors for air-conditioning and refrigeration units. It has an advantage over the capacitor-start motor inasmuch as it…
An induction motor will not always reverse while running. It may continue to run in the same direction, but at a reduced efficiency. An inertia-type…
The capacitor motor is slightly different from a split-phase motor. A capacitor is placed in the path of the electrical current in the start winding…
The repulsion-induction motor starts on one principle of operation and, when almost up to speed, changes over to another type of operation. Very high twisting…
One of the most important parts of the single-phase electric motor is the start mechanism. A special type is needed for use with single-phase motors.…
The field of a single-phase motor, instead of rotating, merely pulsates. No rotation of the rotor takes place. A single-phase pulsating field may be visualized…
As previously mentioned, this type of motor is used as a fan motor in refrigerators and freezers and in some types of air-conditioning equipment where…
Most AC motors are of the induction type. They are, in general, simpler and cheaper to build than equivalent DC machines. They have no commutator,…
The use of low-voltage control systems is becoming more widespread as the demand for residential air conditioning increases. This necessitates the use of a transformer…
