This problem is not a big problem, but some users on this issue is not very understanding, do not understand what is missing, in order to facilitate the smooth use of Shaft mounted helical gearboxes, the following Let's take a look at this problem!
When the motor is in the stationary state, if the winding is switched off or the power is turned off, the magnetic field of the winding is equal to each other. The magnetic field is rotated in the opposite direction, and they are equal to the torque of the rotor action. , The direction of the opposite offset each other, zero start torque motor can not start the phenomenon. When this happens, we need to check whether the motor is faulty, check the power circuit is open circuit switch, whether there is a fuse, and then check the three-phase winding with or without the circuit, and restart the motor, if the helical geared motors Barrier failure, can not start, while buzzing, the need to cut off the power in time.
We use the gear motor if there is a phase failure, pay attention to timely downtime check to ensure the use of security.
