TYPES OF ELECTRIC MOTORS BASIC INFORMATION AND TUTORIALS



Types of electric motors. Electric motors are manufactured in a number of different types. They may be divided into three main groups, depending upon the type of electric system from which they are designed to operate: dc, single-phase ac, and polyphase ac.

There are several types of motors in each one of these groups, constructed so that they produce different starting and running characteristics. The principal types of electric motors follow:

Direct-current
Shunt-wound
Straight shunt-wound
Stabilized shunt-wound
Series-wound
Compound-wound
Permanent magnet
Polyphase alternating-current

Induction
Squirrel-cage
Normal-torque, normal-starting-current
Normal-torque, low-starting-current
High-torque, low-starting-current
Low-torque, low-starting current
High-resistance-rotor
Automatic-start
Multispeed
Wound-rotor
Commutator, brush-shifting
Synchronous
Direct-current excited
Permanent-magnet
Reluctance
Single-phase alternating-current
Repulsion
Induction
Shading-pole–starting
Inductively split-phase–starting
Capacitor-type
Capacitor start
Permanent-split capacitor
Two-value capacitor
Repulsion-start, induction-run
Repulsion-induction
Series
Universal
Series-wound
Compensated series-wound
