Description

technical field [0001] The invention belongs to the technical field of electric motors, in particular to an intelligent monitoring system for electric motors. Background technique [0002] Due to the continuous development of electric power technology, it is required to increase the power and reduce the volume in the design of the motor, so that the heat capacity of the motor is getting smaller and smaller, and the overload capacity is getting weaker and weaker. In addition, due to the improvement of production automation, the motor is often required to operate in various motion modes such as frequent starting, braking, forward and reverse, and load change, so higher requirements are put forward for the protection device of the motor. [0003] Because the motor often works in extremely harsh environments such as humidity, high temperature, dust, corrosion, etc., and there are irregularities in the design of the motor and omissions in equipment management, the motor is more l...
