Many friends often hear about internal rotor motors and external rotor motors, and have been curious about what the differences are and how they work and what the differences in function are. Hope it can help you!
Inner rotor is mainly a rotating body supported by inner bearing, and outer rotor is an outer rotating body supported by bearing, both of them adopt rigid connection or additional shaft. The operating principle of the rotor is that in an asynchronous motor, the rotor, consisting of closed conductors, produces high-speed rotational motion, driven by the rotating magnetic field generated by the stator winding.
The center of the motor is the outer rotor, which is mainly used to maintain magnetic balance. Although the outer rotor motor and the inner rotor motor look no different, the actual functions are different.
1. the difference between the inner rotor and the outer rotor lies in their rotational position, an inner rotation and an outer rotation.
2. the outer rotor motor is easy to maintain and dissipates heat better, while the inner rotor motor is more difficult to maintain.
3. the rotational inertia of the outer rotor motor is greater than that of the inner rotor motor, with high torque and low torque, while the outer rotor motor is the opposite.
4. Inner rotor is commonly used in power machinery, such as electric motors, generators, gas turbines, compressors, etc., while outer rotor is usually installed inside the impeller, with good cooling effect.
The above is the introduction of the outer rotor motor and inner rotor motor, as well as the difference between their working principle and role, in fact, no matter which motor, are important power equipment in industry, in the application process, should pay attention to its maintenance and maintenance, to ensure its normal operation.
