Working Principle of Universal Motor your electrical guide

Construction of Universal Motor The construction of universal motor is very similar to a two pole DC series motor. It consists two field coils wound on laminated core connected in series with armature. The iron structure of field, yoke and armature are laminated to reduce the eddy current losses. Such a motor is so designed that it can be operated either on AC or DC supply.

Universal Motor Construction, Working & Applications

Construction. The construction of universal motor is very similar to dc series motor except that whole of its magnetic path is laminated. The laminated stator is necessary because the flux is alternating when motor is operated from ac supply. The armature is of wound type and similar to that of a small dc motor.

Universal motor Wikipedia

The universal motor is a type of electric motor that can operate on either AC or DC power and uses an electromagnet as its stator to create its magnetic field. It is a commutated series-wound motor where the stator's field coils are connected in series with the rotor windings through a commutator. It is often referred to as an AC series motor. The universal motor is very similar to a DC series motor in construction, but is modified slightly to allow the motor to operate properly on AC powe

How can a universal motor operate on either DC or AC supply?

May 15, 2018· A universal motor is a series-wound motor — meaning that the field and armature windings are connected in series — and is mechanically commutated with brushes and a commutator. Although its construction is very similar to a series-wound DC motor, a universal motor incorporates several modifications that allow it operate properly on either

Advantages and disadvantages of universal motor

As construction of universal motor is similar to the series DC motor. So similar to series DC motor, at no load very high current will flow causing the motor to attain dangerously high speed. Therefore, the universal motor should have some load at starting in order to provide proper speed control. For this purpose, universal motors usually have
