中国电动机

交流感应电动机 :  Huifeng’s Chinese electric motor –  AC induction motors is operated by a rotating magnetic field generated by the stator windings.

The Key advantages of Huifeng’s Chinese electric motor – AC induction motors include:

• Robust & Simple: Robust construction, Huifeng usually use aluminum housing, stainless steel housing, cast iron housing, rolled steel housing, the main material of end shield are aluminum, cast   iron end shield is also required in some tough environment.

Comparing to Permanent magnet motor, or DC motor, AC motor’s components are very simple, endshields, housing, rotor and stator, no maintenance of carbon brush, and magnet, no inverter.

• Cost-Effective: Less maintenance and no inverter .

• Reliable: Less components means less problem, proven technology, tolerant to harsh environments and voltage fluctuations.

• Applications:  Ideal for pumps, fans, conveyors, compressors, and constant-speed applications.

Permanent Magnet Motors (PM Motor): Huifeng’s Chinese electric motor – permanent magnet motors uses strong magnets embedded in/on the rotor to create a constant magnetic field. 

The Key advantages of Huifeng’s Chinese electric motors – permanent magnet motors include:

• Higher Efficiency: The motor can reach IE4 and IE5.

• Higher Power Density: More torque/size or torque/weight than induction motors.

• Better Dynamic Performance: Faster response and higher torque at low speeds.

• Accurate control.

In short: Choose ac induction electric motors for cost, simplicity, and robustness in standard applications. Choose permanent magnet electric motors for maximum efficiency, power density, and dynamic control where a VFD is used.
