Abstract

The invention provides a motor, which comprises a casing, a rear cover, a rotating shaft, a brake and a transformer device, wherein the rear cover is arranged at one end of the casing, and the rear cover and the casing surround to form an installation cavity; the rotating shaft is arranged in the installation cavity In the middle, the rotating shaft is rotatably arranged; the brake is arranged in the installation cavity, the brake cooperates with the rotating shaft, and the brake is used to brake the rotating shaft; With this solution, the voltage of the brake can be adjusted according to the needs due to the transformer device, and the high voltage is used at the beginning of the braking, and the low voltage is used in the process of maintaining the braking, which can reduce the temperature rise of the brake, Improve long-term reliability. Moreover, the transformer device is arranged on the rear cover, so that the structure of the motor is compact. The brake and the encoder share the power supply, which avoids the occupation of equipment space by excessive power cables and simplifies the wiring and wiring of the equipment system.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to a motor. Background technique [0002] With the development of high-efficiency and energy-saving technology for motors, the application range of permanent magnet synchronous motors in the market is becoming more and more extensive. Permanent magnet synchronous motors have the characteristics of high efficiency, energy saving, high power factor, and good torque. In order to better serve the intelligent equipment market, the integration of permanent magnet synchronous motors has become one of the important development directions of servo control systems. [0003] In many motors, an electromagnetic brake is usually provided to brake the rotating shaft in the motor. At the beginning of braking, in order to ensure the success of braking, the brake needs a relatively large voltage, and in the process of maintaining braking, the brake can use a relatively small voltage. However...
