Compressor quality will affect the service life of air energy water heater?

Compressor quality will affect the service life of air energy water heater? The compressor is the core component of the air energy water heater, and is called the "heart" of the air energy equipment. The quality of the compressor directly determines the service life of the air energy heat pump. At present, the quality of compressors produced by several international manufacturers is relatively good, and can reach a relatively long service life.

Working principle of servo motor (how servo motor works)

The rotor inside the servo motor is a permanent magnet. The U / V / W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the effect of this magnetic field. At the same time, the encoder of the motor feeds back the signal to the driver. The driver adjusts the rotation angle of the rotor according to the comparison between the feedback value and the target value. The accuracy of servo motor depends on the accuracy of encoder (number of lines).
