- Company Profile:
A DC motor which changes speed only slightly from a no load to a full load condition. In AC motors, these are synchronous motors.
Industry:Electrical equipment
The iron portion of the stator and rotor; made up of cylindrical laminated electric steel. The stator and rotor cores are concentric separated by an air gap, with the rotor core being the smaller of the two and inside to the stator core.
Industry:Electrical equipment
The induced voltage in a motor armature, caused by conductors moving through or "cutting" field magnetic flux. This induced voltage opposes the armature current and tends to reduce it.
Industry:Electrical equipment
The mechanical connector joining the motor shaft to the equipment to be driven.
Industry:Electrical equipment
The time rate of flow of electrical charge and is measured in amps (amperes).
Industry:Electrical equipment
One complete reverse of flow of alternating current per rate of time. (A measure of frequency.) 60 HZ (cycles per second) A.C. power is common throughout the U.S. and 50 HZ is more common in some foreign countries.
Industry:Electrical equipment
A special end shield with holes for through bolts in the flange and is primarily used for mounting the motor on gear boxes or bulkheads. Standardized for frames 143T through 445T. "D" flanges are not threaded and the bolt holes extend beyond the motor frame.
Industry:Electrical equipment
A current that flows only in one direction in an electric circuit. It may be continuous or discontinuous and it may be constant or varying.
Industry:Electrical equipment
A motor using either generated or rectified D.C. power (see Motor definition) . A DC motor is usually used when variable speed operation is required.
Industry:Electrical equipment
A definite purpose motor is any motor design, listed and offered in standard ratings with standard operating characteristics with special mechanical features for use under service conditions other than usual or for use on a particular type of application. (NEMA
