What kind of motor is the cutting machine?
Besides the excitation winding F and the commutating pole winding FD, the stator is additionally provided with a compensation winding Fs to limit the excessive reactance voltage drop of the armature winding during the AC operation and to improve the commutation.
Only to make it suitable for AC operation, all magnetic circuit systems are made of laminations to reduce eddy currents.
The motor is essentially a DC series motor.
AC DC motor is a series of AC motors, which can be supplied by alternating current or by DC power supply, also known as universal motors
Dual purpose series motor for AC and DC purposes.
