Question
Chapter 17, Problem 1RQ
To determine
The three basic types of three-phase motors.
Expert Solution & Answer
Explanation of Solution
The three basic types of three-phase motors are as mentioned below.
- 1. Synchronous motors: The AC motor in which the rotation of the shaft can be synchronized by the frequency of the supply current is called Synchronous motor.
- 2. Wound rotor induction motors: An induction motor in which rotor winding is connected to external resistance through slip rings is called wound rotor induction motor.
- 3. Squirrel cage induction motor: The induction motor in which the rotor being used is shaped in the form of a cage of squirrel is called Squirrel cage induction motor.

- 12. Figure Q12 shows a prospective design for a conveyor roller system, for transferring crates, one at a time. The system is made up of two parallel rectangular steel beams, built-in at one end and simply supported at the other, with closely spaced rollers mounted in-between, for the crate to pass over. a) Using Macaulay notation, carry out an analysis of the problem and calculate the deflection of the mid-length point of the beams when the crate is centrally located, midway between A and B. State any important assumptions used in your analysis.
