High-speed motor talk: What are the uses of high-speed motors?

High-speed motors are different from low-speed motors, the most important being the difference in speed. The traditional three-phase asynchronous motor is frequency-modulated by the inverter (2P motor rated 3000) with a limit of 4500 rpm. In theory, motors over 3,000 rpm can be used as high speed motors. Most of the high-speed motors used in industry are also asynchronous motors, which have obvious cost advantages and are relatively easy to popularize.

When it comes to the application of high-speed motors, the speed performance, different application requirements are different, for example.

The high-speed motor for high-speed metal cutting machine is generally around 6000 rpm. Due to the high material density, the metal cutting has certain requirements on the torque, and the rotation speed is not too high.

Woodworking equipment (edge banding machine, slotting machine, etc.) 9000-18000 rev / min See the actual application, high speed brings efficiency improvement, and the material surface treatment process requirements.

Engraving machine motors (carpentry, stone, glass, jade, etc.) are generally around 18000-24000 rev / min, the torque requirements are not high, but the accuracy is required.

The PCB drilling machine has a capacity of 100,000-300,000 rpm, and our medical dental processing equipment has more than 300,000 rpm.

The motor power used in these industries ranges from a few hundred w, and the maximum is basically a dozen or so KW. The industrial requirements are basically met. At present, the domestic high-speed motor technology of 100,000 rpm is still very backward, and all the colleagues in the manufacturing industry need to work together.
