How to solve the phenomenon of temperature rise of China high voltage dc motor
The micro-reducer motor can use the gear reducer to obtain any fixed speed, and it can also achieve the goal of stepless speed regulation through the electronic governor. However, when we use it, we often experience a phenomenon in which the temperature of the micro-reduction motor is too high. The solution is:
The stator winding or interphase short-circuit or grounding can be used to increase the current, increase the strain and overheat. If the failure is not serious, just re-package insulation, serious should be replaced windings.
2, the damage or wear of the bearing is too large, so that the stator and the rotor touch each other, can check whether the bearing is loose, whether the stator and the rotor are poorly assembled.
3, if the voltage exceeds 10 % of the rated voltage of the DC motor, or less than 5 % of the rated voltage of the DC motor, the DC motor is prone to heat and temperature increase under the rated load. The voltage should be checked and adjusted.
4, cage rotor break or winding rotor coil joint loose, causing the maintenance network current is too large and hot. Copper bar rotor may be welded or replaced, cast aluminum rotor should be replaced.
In many cases, when consumers choose electric motors, they will often be unable to meet their needs because of the high speed or too small torque of the single motor of the micro-reducer motor. In fact, we can tell you that the speed of the micro-reducer motor can completely meet your work needs..
