Abstract

The invention relates to a load system for motor type detection, and the system is characterized by comprising a double-output shaft loading motor, wherein one output shaft of the double-output shaftloading motor is connected to a servo brake device, the loading force loaded on the shaft end of the double-output shaft loading motor is adjusted by adjusting the opening of the servo brake device, and the other output shaft is coupled to the output shaft of the motor under test via a torque speed sensor. The invention provides an integrated load system, which can realize the torque test of the motor stalling in one installation, can also realize the loading test of the motor, and can realize zero speed of the M-S test.

Description

technical field [0001] The invention relates to a load system which adopts a brake system to realize zero-speed lock-up and locked-rotor tests of a motor, and belongs to the technical field of motor type detection. Background technique [0002] At present, in the motor type inspection, the stall test is a test item independent of the load test, and generally adopts the following methods: figure 2 The test method shown, figure 2 Among them, the tested motor 4 is connected to one end of the force arm 5, and the other end of the force arm 5 is connected to the sling 7 suspended on the support 6. There is a sensor 8 on the sling 7, and the sensor 8 is connected to the secondary instrument 9. The force arm 5 There is a spirit level 10 on it. pass figure 2 The torque arm device indirectly measures the motor stall torque, and the steering identification is required during the test, which is completely different from the installation method of the motor-to-drag test, such as fi...
