    ), and 1,200/600 rpm (6/12 pole). Two-winding ac motors have two separate windings that can be wound for any number of poles so that other speed ratios can be obtained. However, ratios greater than 4:1 are impractical because of ac motor size and weight. Single-phase multispeed ac motors are usually

This application note discusses the basics of an AC induction motor; the different types, their characteristics, the selection criteria for different applications and basic control techniques.

  • AC Motors
    A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary. The primary winding (stator) is connected to the power source and the shorted secondary (rotor

    than the PIC18F452 or PIC16F7X7. Practically speaking, control of a 3-phase AC induction motor requires pulse-width modulated control of the six switches of a 3-phase inverter bridge connected to the motor's stator windings (Figure 1). The six switches form 3 pairs of "half-bridges", which can

    Film. A Permanent-Split-Capacitor motor is similar to a CS motor and also contains two windings:  a main winding and a capacitor winding.  In a PSC motor, however, the capacitor winding is permanently connected in series with an AC oil-type or metallized film capacitor.  Unlike the CS motor
  • AC Induction Motors and Traction Design Motors
    AC induction motors and traction design motors are a class of devices which derives its name from the fact that current is induced into the rotor windings without any physical connection to the stator windings (which are directly connected to an AC power supply). AC induction motors and traction

There are several important differences between linear and rotary induction motors that bear on selection. Unlike rotary motors, the linear motor
