Description

technical field

[0001] The invention relates to an electric motor power-saving protection device, in particular to an electric motor intelligent power-saving protection device in industrial and civil mechanical equipment. Background technique

[0002] Most of the mechanical equipment in all walks of life use electric motors as transmission devices. According to the standard, when almost all mechanical equipment is configured with a motor, the motor must be selected according to the maximum load of the mechanical equipment during actual operation, and a certain margin is reserved for the power configuration of the motor to meet the requirements of the actual operation of the mechanical equipment. the greatest need in the process. At the same time, in the actual operation process of mechanical equipment, it is generally operated under the condition of unsteady load or load changing frequently. On the other hand, when the motor starts, it will generate a large instantaneous c...
