Large Electric Motors: EMQ bearings

Large Electric Motor

Large Electric Motor is an automatic device that uses error-sensing feedback to correct the performance of a mechanism. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position or other parameters. For example, an automotive power window control is not a electric motor, as there is no automatic feedback which controls position—the operator does this by observation.

Stepper Motor: EMQ bearings

Stepper Motor

A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. The stepper motors are good at starting, stopping and reversing, and the stepping motor can achieve very low speed synchronous rotation with a load that is directly coupled to the shaft.

Industrial DC Motor: augular contact ball bearings

Industrial DC Motor

Industrial DC motor is an electric motor that runs on direct current (DC) electricity. By far the most common DC motor types are the brushed and brushless types, which use internal and external commutation respectively to create an oscillating AC current from the DC source. Industrial DC motors are commonly used as the drive for rolling mills to stimulate the action of hoisting up, pressing down, rolling, etc.

Synchronous Electric Motor Application: roller bearings and ball bearings

Synchronous Electric Motor

Synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it. Synchronous Electric Motor is high power, high starting torque and long life. They are widely used in large machineries, fans, pumps, compressors, rolling mill and some miniature equipments. Therefore, WD energy bearings, with high speed, low noise and long life, are available in synchronous electric motors.

Asynchronous Electric Motor: roller bearings and ball bearings

Asynchronous Electric Motor

Asynchronous electric motors, with compact design, low maintenance and initial cost, are widely applied in driving machine tool, pump, fan and mining machinery, and they are especially used in electric fans, refrigerator, air-conditioning and other Household Electric Appliance. The bearings used in asynchronous electric motors are high speed, low noise and can work under the high temperature.
