Eddy current losses can be minimized by laminating the core and insulating the core from each other with paper or varnish.

The electric motor that converts the AC electrical energy into mechanical energy by using an electromagnetic induction phenomenon is called an AC motor. Electrical machines that convert DC electrical energy into mechanical energy is known as a DC motor. The universal motor is a type of electric motor that can operate on either AC or DC supply. A universal or AC series motor is similar to a DC series motor which has an armature and field windings connected in series. Since the field flux and armature current reverse simultaneously, the direction of torque always remains the same irrespective of its polarity.
