Performance characteristics of Panasonic Minas series Panasonic AC servo

The output power of Panasonic AC servo motor is generally 0.1-100 W, and the power frequency is divided into 50 Hz, 400 Hz, etc. It is widely used in various automatic control and recording systems 1.Miniaturization design 1) Through the best thermal analysis of the driver, the miniaturization is realized. Compared with the past, the volume is 75% and the weight is 80% 2) The new punching process of thin die steel plate has greatly reduced the iron loss, shortened the motor length (70% in the past) and reduced the number of drive models. It adopts current grading method to prepare and maintain. One driver is suitable for multiple motors and can identify automatically.

Excessive head resistance will cause compressor to trip

Excessive head resistance will cause compressor to trip The existence of compressor failure does not seem to have much to do with the brand. In other words, whether it is a Hitachi compressor, a Copeland compressor, or another brand of compressor, as long as it is used for a long time, there will be some problems of failure. . Compressor tripping is a common fault. When this failure usually occurs, we should comprehensively look for the cause of the failure.
