How do | carving machine engraving machine motor heating

Carving machine know carving machine in use motor heating do? Carving motor are composed of iron core and winding wire, the winding wire has resistance, electricity will produce loss. Of course, the loss is determined by the magnitude of the current size to the resolution, which is normally we often say that the copper loss. But if the current DC is not standardized, will produce harmonic loss forget there is hysteresis eddy current effect in the alternating magnetic field, will also have a loss, its size and the data of frequency, voltage, current, relevant, this is called iron loss.
Carving machine learned engraving machine in use motor easily fever, copper loss and iron loss will be displayed in the form of heat, thus affecting the efficiency of the motor. The common pursuit of the stepper motor positioning accuracy and torque output, low comparative efficiency, current is compared commonly big, and the harmonic components of high current, alternating frequency also increases with the the speed change, therefore the stepper motor heating condition exists generally, and the condition is more serious than the ordinary AC motor.
Engraving machine motor easy to heat, if processing motor heating will have two directions to reduce the copper loss and iron loss reduction of copper loss, how to reduce the motor heating reduces fever. Reduce the electric carving machine Yin and current, suggest that the selection is the best choice of small resistance and rated current of small motor, the motor, can no shunt motor connected in series with the motor, but it is often associated with torque and speed request inconsistent. Motor on once selected, it should make full use of the drive of automatic flow control function and off-line function, the former in the motor in the automatic reduction of current static state, the latter have cut off current.
