Automatic separation of the automatic separating deceleration motor and its versatility

May 11, 2019

The automatic separating deceleration motor has a wide range of applications during use, which can reduce the inertia and impact force of the motor when it is instantaneously stopped, and can also be used for parking up and down or vertical lifting. Avoid the motor slipping down during the shutdown. Therefore, the brake is divided into a single-sided brake and a double-sided brake power supply. The brake armature is released and the spring resets the armature to the friction disc. The motor shaft is held by the friction disc and the brake is kept under load.

 

The automatic separation gear motor will wear out during the use of the brakes. During operation, its good brake pads are wear-resistant and the braking force is maintained. However, for long time and frequent use, check the brake wear and avoid the brakes. And invalid. The inspection method is to open the hood of the motor and adjust the gap of the brake. The clearance is 0.4-0.7mm. If the wear is serious, it is recommended to replace the brake assembly. When the brake motor and the inverter are used together, the brake power supply should be separately connected to prevent the frequency conversion from being caused by the brake to damage the motor and the brake.

 

The automatic separation geared motor has an electromagnetic brake at the end of the motor. When the motor is energized, it is also energized and pulled. At this time, it does not brake the motor. When the motor is de-energized, it also loses power. The motor is braked by the spring. Rotor open circuit voltage measurement When the rotor open circuit voltage is measured, the rotor is stationary, the rotor winding is open, the starting varistor is disconnected, the rated voltage is applied to the stator winding, and the voltage between the lines is measured between the rotor slip rings. The rated voltage is above 500V. The variable speed reduction motor can be appropriately reduced in voltage applied to the stator windings.
