Motors

Revolutions per minute (R.P.M.)

Electrical equipment; Motors

The number of times per minute the shaft of the motor (machine) rotates. This is a function of design and the power supply.

Random wound

Electrical equipment; Motors

The standard type of stator winding used in motors under 1,000 volts. The coils are random wound with round wire as opposed to flat form wound coils.

Resistance thermal detectors (RTD)

A resistance device used to measure temperature change in the motor windings to detect a possible over heating condition. These detectors would be embedded into the winding slot and their resistance ...

Bearing rtd

Electrical equipment; Motors

A probe used to measure bearing temperature to detect an overheating condition. The RTD's resistance varies with the temperature of the bearings.

Reactance (inductive)

Electrical equipment; Motors

The characteristic of a coil, when connected to alternating current, which causes the current to lag the voltage in time phase. The current wave reaches its peak later than the voltage wave reaches ...

Relay

Electrical equipment; Motors

A device that is operative by a variation in the conditions of one electric circuit to effect the operation of other devices in the same or another electric circuit.
