A universal motor is a special type of motor which is designed to run on either DC or single phase AC supply. These motors are generally series wound (armature and field winding are in series), and hence produce high starting torque (See characteristics of DC motors here). That is why, universal
• Universal motors are mostly operated on AC power, but they can operate on either AC or DC. Tools and appliances with UMs are among the most frequent applications. • A universal motor has both a wound field (on the stator) and a wound armature (on the rotor).
This motor terminology glossary is guide to explain and define a variety of terms and characteristics that apply to industrial AC and DC electric motors. The commonly available electric power supplied by an AC generator and is distributed in single- or three-phase forms. AC current changes its direction of flow (cycles).

Ex. 2-1 The Separately-Excited DC Motor ..... 67 Operation of a separately-excited dc motor. Simplified equivalent circuit of a DC motor. Relationship between the no-load speed and the
The universal motor is basically a series DC motor which is specially designed to operate on AC as well as on DC. A standard DC series motor has very poor characteristics when operated on AC, mainly due to two reasons:
Universal ac Series Motor The universal ac series motor, so called because it “can” operate on either ac or dc supplies. Within limits, for a given voltage and frequency, will give approximately the same performance on either ac or dc. This requirement is/was seldom needed in Australia, but historically was very
universal motor are armature, field winding, stator stamping, frame and plate, and polish. The universal motor is a type of electric motor that can run on either AC or DC power and creates its magnetic field with an electromagnet as its stator.
