Torque motor produces heating phenomenon, a large part of the reason is that in the selection, the selected output torque is not enough, too small output torque is used on the larger load equipment, it is very easy to cause heating phenomenon, then the following is a simple understanding with Senli Xiaobian.

       At present, the widely used three-phase asynchronous motor often appears in the use of its own working temperature rise until it can not work, you can see whether the motor is in a long-term overload operation state, which will cause the winding current is too large, so that the winding heat increase caused by high temperature.

       For example, in some special occasions, the startup is too frequent, and the current at the start is the normal working current2More than that, will also cause The heating of the winding increases, resulting in excessive temperature.

       Like torque motor in the selection, we should pay attention to the choice of speed range, in generalTorque motorWe are all used for winding, so the selection of the selected output torque should be similar to the required torque, avoid choosing too large, otherwise too large output torque used on small load equipment, will make the input voltage of the motor drop very low. When the voltage is too low, the torque speed curve of the motor is relatively flat, which makes the winding accuracy worse, that is, the load change and the speed change appear inconsistent.
