The maximum torque that an ac motor will develop with rated voltage applied at rated frequency without an abrupt drop in speed. Also termed pull-out torque or maximum torque.

A synchronous machine used to convert mechanical power into alternating current electric power.

The temperature of the surrounding cooling medium. Commonly known as mom temperature when the air is the cooling medium in contact with the equipment.

Measure of current flow in electrical circuit.

E - A vibration reading taken when a machine is in good operating condition that is used as a reference for monitoring and analysis.

Supports, guides, and reduces the friction of motion between fixed and moving machine parts.Sleeve: Preferred where low noise is important as on fan and blower motors.Ball: Used where high shaft load [..]

A letter which appears on the nameplates of ac motors to show their locked-rotor kilovolt amperes per horsepower at rated voltage and frequency.

A term used to describe a multi-speed motor in which the rated horsepower is the same for all operating speeds. When applied to a solid state drive unit, it refers to the ability to deliver constant h [..]

A multi-speed motor for which the rated horse power varies in direct ratio to the synchronous speeds. The output torque is essentially the same at all speeds.

A three-phase winding connection in which the phases are connected in series to form a closed circuit-
