Everyone in the electromechanical industry should know that noise is an important indicator of motor production, which has attracted widespread attention. Motor noise has always been a difficult problem to solve, mainly through the combined influence of electromagnetic, mechanical and ventilation factors. The best way to reduce the noise of the motor is to find the source of the noise, or use some technological means to reduce the noise of the motor. The following are the methods of reducing mot

The motor does not turn and there is no sound. The reason is that there is a two-phase or three-phase open circuit in the motor power supply or winding. First check for supply voltage. If there is no voltage in three phases, the fault is in the circuit; if the three-phase voltages are balanced, the fault is in the motor itself. At this time, the resistance of the three-phase windings of the motor can be measured to find out the windings with open phase.

Due to the continuous development of insulation technology, the design of the motor requires both increased output and reduced volume, so that the thermal capacity of the new motor is getting smaller and smaller, and the overload capacity is getting weaker and weaker; due to the improvement of the degree of production automation , the motor is required to operate in frequent starting, braking, forward and reverse rotation, and variable load modes, which puts forward higher requirements for the m
