A relay, the principal function of which is to protect service from interruption, or to prevent or limit damage to apparatus.
Industry:Electrical equipment
The maximum constant torque which a synchronous motor will accelerate into synchronism at rated voltage and frequency.
Industry:Electrical equipment
The minimum torque developed by an AC motor during the period of acceleration from zero to the speed at which breakdown occurs. For motors which do not have a definite breakdown torque, the pull-up torque is the minimum torque developed during the process of getting up to the rated speed.
Industry:Electrical equipment
The number of times per minute the shaft of the motor (machine) rotates. This is a function of design and the power supply.
Industry:Electrical equipment
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.
Industry:Electrical equipment
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 varies with the temperature.
Industry:Electrical equipment
A probe used to measure bearing temperature to detect an overheating condition. The RTD's resistance varies with the temperature of the bearings.
Industry:Electrical equipment
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 its peak.
Industry:Electrical equipment
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.
Industry:Electrical equipment
The characteristic of a magnetic material which resists the flow of magnetic lines of force through it.
