The performance testing of DC motor test bench usually includes: thermal test (temperature rise), no-load test, load test, locked rotor test, M-S curve, etc. Inverter, synchronous motor (permanent magnet), DC motor, servo motor, electric vehicle motor, DC brushless motor, switched reluctance motor, etc. also have their own testing projects. To complete the above tests, the testing equipment must have good load capacity. Better load selection: We know that general loads, such as eddy current dynamometers, resistance load generators, etc., are only suitable for loading at high speeds. Magnetic powder brakes are only suitable for loading at low speeds and all energy is dissipated in the form of heat... Large motor users are generally suitable for loading at high speeds, while magnetic powder brakes are only suitable for loading at low speeds and all energy is dissipated in the form of heat.
The DC motor test bench has excellent loading characteristics, such as four quadrant operation, fast response speed, small space occupation, simple operation, energy feedback and utilization during loading, and good energy-saving effect. So electric loading is a better choice for various motor test loads. A better alternative to unit loads: Electric loaders are an ideal replacement and upgrade product for unit loads commonly used in previous motor tests. Compared with unit loads, they have unparalleled advantages: as long as one motor is equipped with one loading controller, it can greatly reduce plant investment; Equipment investment is lower than unit investment; Low speed performance is better than the unit; Easy to operate and use, and can achieve true soft start; Easy to implement computer automated testing. Wait a moment, it is an ideal choice for motor users, especially those who are renovating laboratories.
