What are external and internal rotor motors? What is the difference and difference in working principle? - CE Certificate Automatic Stator Motor Transformer Toroidal Coil Winding Machine Manufacturer -Vacuz

Many of you have asked the question, what are external and internal rotor motors? What is the working principle of the two? What is the difference? Here Vacuz gives you an explanation and introduces what is an external rotor motor? What is the inner rotor motor? The working principle and the difference between the two are introduced, Vacuz hope it can help you!

Inner rotor is the rotating body supported by inner bearing, outer rotor is the rotating body supported by bearing, both are rigid connection or additional shaft. The working principle of the inner rotor: the rotating magnetic field generated by the stator winding, driving the rotor in the motor to produce high-speed rotational motion.

What is the difference between an external rotor motor and an internal rotor motor?

The center of the motor is the outer rotor, which is mainly used to maintain magnetic balance. Although the outer rotor motor and inner rotor motor don’t look different, how does it actually function?

1. the difference between the inner rotor and the outer rotor lies in their rotational position, one rotating inside and the other outside.

2. The outer rotor motor is easy to repair and dissipates heat better. Inner rotor motor maintenance is more difficult, maintenance is more difficult, the internal coil is not well wound.

3. the rotational inertia of the outer rotor motor is greater than the rotational inertia of the inner rotor, while the outer rotor motor is just the opposite.

4. Inner rotor is commonly used in motors, generators, gas turbines, compressors and other power machinery, while outer rotor is usually used in impellers with good cooling effect.

The above is an introduction to external rotor motor and internal rotor motor, as well as the working principle and functional differences between the two, which will hopefully help you understand the relevant knowledge. In fact, no matter which motor is the more important mechanical equipment in industrial production, in the process of use, should pay attention to its maintenance and maintenance to ensure its normal operation.
