Why is the stepper motor very hot?
There are several reasons for the serious fever in stepping motors:1 、 the current set by the drive is higher than the rated current of the motor.2, the motor speed is too fast.
3, the motor itself inertia and positioning torque, so even if the medium speed operation will be hot, but does not affect the motor life
If it is overheated during operation, it may be that the driving current is too large and that the drive current can be properly reduced. General heating is quite normal, as long as not more than the normal working temperature is no problem
The motor demagnetization point at 130-200 DEG C, so the motor in 70-90 C is a normal phenomenon, as long as less than 130 DEG C is generally not what the problem is, if you really feel hot, put the drive current is about 70% of the rated current of motor or motor speed reduction.Remarks: under normal circumstances, fever caused by the above, but without excessive worry, are the power of the larger reason, if too hot, you can turn off the power, cooling and then use.
