asynchronous external rotor motor

asynchronous external rotor motor

In this asynchronous external rotor motor, the stationary part, the stator, is located inside and is surrounded by the rotating part, the rotor. The externally positioned rotor rotates around the inner stator. With this arrangement, the outer rotor motor can achieve higher torque (magnet volume, air gap surface, radius) than the inner package rotor of the same package length, the same magnet system and the same magnet thickness (reduced magnet) Volume, reduced air gap surface, smaller radius).
Product description

Product introduction:

In this asynchronous external rotor motor, the stationary part, the stator, is located inside and is surrounded by the rotating part, the rotor. The externally positioned rotor rotates around the inner stator. With this arrangement, the outer rotor motor can achieve higher torque (magnet volume, air gap surface, radius) than the inner package rotor of the same package length, the same magnet system and the same magnet thickness (reduced magnet) Volume, reduced air gap surface, smaller radius).

Product features:

1. Asynchronous external rotor motor's sinusoidal commutation design also provides exceptionally low noise operation. This product (rotor rotating outside the stator) has a larger magnetic flux than a rotor-centered permanent magnet motor. It has higher power density, higher torque density and improved long-term reliability.

2. The main goal of this asynchronous external rotor motor design is to maximize the motor output rating while minimizing its quality. In the set diameter, the outer rotor topology has a longer radius than any other topology, resulting in greater torque with less material.

3. This is a motor with a large number of magnetic poles and round magnets. It allows for a lighter rotor and stator (reduced back iron). Near sinusoidal currents and voltages produce less harmonic frequencies, which increases efficiency. Its cogging torque is low.
