Matters needing attention

1.Oil and water protection of servo motor 1) The servo motor can be used in the place that will be attacked by water or oil drops, but it is not completely waterproof or oil-proof. Therefore, the servo motor should not be placed or used in the environment of water or oil invasion. 2) If the servo motor is connected to a reduction gear, the oil seal should be filled when using the servo motor to prevent the oil of the reduction gear from entering the servo motor 3) The cable of servo motor should not be immersed in oil or water.

Why the air conditioner does not cool

The cooling load is overloaded or the space is too large, the number of air conditioners is not correct; improper installation will cause poor air circulation, resulting in poor cooling effect; when the freon in the air conditioner is insufficient, it will cause the cooling effect of the air conditioner to deteriorate; the air conditioner is not on time Do cleaning and maintenance, etc.

The key detection items of servo motor and common problems in servo motor detection

1).Servo motor detection -- cogging torque: Cogging torque is an inherent phenomenon of permanent magnet motor, which can make the motor torque fluctuate and produce vibration and noise. We measure the change of motor torque in a rotation cycle on a special test bench and analyze the distribution of cogging torque.
