Tool and method for detecting performance of electromagnetic band-type brake of in-service motor

Abstract

The invention discloses a tool and method for detecting the performance of an electromagnetic band-type brake of an in-service motor. The device comprises a locking device and a torque detection device. The locking device comprises a locking base plate, a full-thread screw, a connecting bolt, a gasket and a connecting nut, the gasket and the connecting nut are matched, two hole channels are formed in the locking base plate, a U-shaped hole channel is formed in the outer side of the locking base plate and used for allowing the full-thread screw to penetrate through, and a kidney-shaped hole channel is formed in the inner side of the locking base plate and used for fixedly connecting the locking device with the driving motor and the driving gearbox; the torque testing device comprises a torque wrench and a special sleeve head. The method comprises the steps of installing a tool with the electromagnetic band-type brake performance for operation and connecting a motor rotor shaft to the torque detection device through a special sleeve head. According to the tool and method for detecting the electromagnetic band-type brake performance of the in-service motor, the electromagnetic band-type brake capacity of the motor can be judged.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a tool and a method for detecting the performance of an electromagnetic brake of an in-service motor. Background technique [0002] As a clean and pollution-free renewable energy, wind power has its own advantages. In recent years, the construction of wind power projects in my country has developed rapidly. The motors in many parts of the wind turbine are braked by electromagnetic brakes. The accuracy of the rotational position of the motors is an important guarantee to ensure the safe operation of the unit. At present, during the operation and maintenance of wind turbines in service, the electromagnetic brake capacity of the motor has not been tested, and it is impossible to judge whether the electromagnetic brake capacity of the motor meets the operation requirements of the unit. [0003] Through patent search, it is found that the current method and ...

At present, during the operation and maintenance of wind turbines in service, the electromagnetic brake capacity of the motor has not been tested, and it is impossible to judge whether the electromagnetic brake capacity of the motor meets the operating requirements of the unit

[0003] Through the patent search, it was found that the current method and device for testing the electromagnetic brake capability of the motor need to use electric drive and control procedures, and the operation and testing process is relatively cumbersome, especially for the inconvenient and narrow space for obtaining power and fixing the motor, and the measurement has certain limitations. Sexuality and high equipment cost, it has not been popularized and applied in practice
