The signal output end of the motor economizer is connected with the signal input end of the three-phase asynchronousmotor. The signal input end of the data acquisition platform is connected with the signal output end of the coupling and torque and rotational speed sensor, the temperature signal and magnetic induction intensity signal output end of the three-phase asynchronous motor and the signal output end of the differential pressure transmitter. The signal output end of the data acquisition platform is connected with the signal input end of the AC voltage stabilized power supply. The motor energy saving key technology test platform can stably operate for a long time so that the regulation precision is high, the detection data are true and accurate and the service life is long.

Description

technical field [0001] The invention relates to a test platform for motor energy-saving technology. In particular, it relates to a test platform for key technology of motor energy saving which can test the energy saving effects of various motor power saving products. Background technique [0002] The electric energy consumed by three-phase asynchronous motors accounts for more than 40% of the total electricity consumption in the world, and 60% of the electric motors have low operating efficiency, resulting in a large amount of waste of electric energy. In the context of increasingly tight energy sources, if the three-phase asynchronous motor can be energy-saving, then the power saving is very considerable. Therefore, experts and scholars at home and abroad have invested in the field of research on energy saving of motors, and started the research and development of power savers for motors. At present, there are three main categories of motor energy-saving products on the m...

Problems solved by technology

[0002] Three-phase asynchronous motors consume more than 40% of the world's total power consumption, of which 60% of the motors operate inefficiently, resulting in a large amount of waste of electric energy

Whether it is a DC generator or a dynamometer, it is not the actual load of the motor, but a simulated load. The biggest problem with the simulated load of the motor is heat and cannot run for a long time

Heat will cause the load to change, which makes the test data unreliable

On the other hand, the motor simulation load cannot truly simulate the actual motor load
