First, the automatic transmission reducer motor will be formed when the light load is running

1 、 low power factor of motor;

2. Low motor power;

3, the equipment will be destroyed, the operation is uneconomical.

Two, automatic equipment drive speed motor should not be used for a long time

A long time without stopping, CNC cutting machine control system, circuit system and transmission system will result in loss, CNC cutting machine drive motor in the condition for a long time if the demand from the application demand, pay attention to the following details:

1. Measure the insulation resistance between stator and winding and winding to ground.

2, the insulation resistance R should be satisfied with the following formula: R > un/ (1000+p/1000) (M omega)

UN: motor winding extra voltage (V) P: motor power (kw)

About UN = 380V motor, R > 0.38M omega. Such as low insulation resistance:

1) motor no-load operation 2 ~ 3H drying; 2) with 10% extra voltage low-voltage AC electric cable into the winding, or three-phase winding series connected with DC baking, adhere to the current in 50% of the extra current; 3) use the fan to send hot air or heating element heating.

3. Finishing motor.

4, replace bearing grease.

Three, the automatic equipment transmission deceleration motor current should not be maladjusted

CNC cutting machine drive motor current imbalance will cause damage to the motor, resulting in the formation of current imbalance included:

1. Unbalanced three-phase voltage;

2, the motor internal part of the branch welding bad or touch is not good;

3. Wiring fault.
