Why motor rotor ring magnet need to be oblique angle magnetization?

The rotor ring magnet of the motor is a crucial part of the motor, which determines the performance and efficiency of the motor. In order to achieve better results, some engineers will design the magnet to be magnetized at an oblique angle (slant angle), and the following will introduce you to several reasons for such a magnetization treatment.

Increasing torque

Often a certain bevel angle is applied to the rotor magnets, and the addition of the rotor magnet bevel angle can play a good role in increasing the torque.

When the motor generates a load in the work, the rotating speed of the motor will become slower, and also the torque of the motor will be decreased. And through the design of beveled angle, the torque of the motor can be improved to a certain extent, so that the motor can work better under load.

More stable rotation

The design of oblique magnetic field can make the rotation of rotor more stable and reduce vibration and noise. High-speed rotation of the motor, its rotor vibration and noise is difficult to avoid. And through the design of the rotor magnet inclined angle, can also play a certain role in reducing vibration and noise.

Increased efficiency

The efficiency of the motor can be improved by the design of the rotor magnet beveling. Because the magnetic field is more evenly distributed, the motor's magnetic field utilization is higher. As a result, the power consumption of the motor will be smaller under the same load and the efficiency will be higher.

Adapting to special operating requirements

In special applications, such as high-speed motors or precision-controlled motors, the rotor's magnetic field needs to be finely tuned at multiple angles to adapt to changing load requirements. Inclined angle magnetization provides greater flexibility in magnetic field control, allowing the motor to maintain efficient and stable performance under different operating conditions.

The above is the explanation of the title of the article to illustrate that oblique angle magnetization has become one of the key means to enhance the performance of electric motors, especially in the design of high-performance motors and high-speed motors, which has a role that cannot be ignored.
