What is 3phase induction motor PDF?
Introduction: The three phase induction motors are simple in construction, rugged, low cost and easy to maintain. They run at a constant speed from no-load to the full load. Therefore, these motors are frequently used in industry. Induction Motor Parts.
What is a single phase induction motor?
Single-Phase Induction Machines. Single phase induction motors generally have a construction similar to that of a three phase motor: an ac windings is placed on the stator, short-circuited conductors are placed in a cylindrical rotor. i.e. the cross product of flux densities will be zero, the motor produces no torque.
What are the 5 types of a single-phase motor?
There are 5 types of single-phase induction motors on the basis of their starting methods: Resistance start, Capacitor start, Capacitor start capacitor run, Permanent Capacitor, and shaded-pole single-phase induction motor. Each of them is discussed in detail below.
Which type of rotor is used in single-phase motors?
The rotor in the single-phase induction motor is of squirrel cage rotor type. The construction of single phase induction motor is almost similar to the squirrel cage three-phase induction motor.
What are the 2 types of induction motor?
Single-phase induction motors and three-phase induction motors are the two main types of induction motors.
Where are single-phase induction motors used?
Uses: Single-phase motors are used in equipment and machines that are smaller in size and require lower horsepower (for example, one horsepower). This include equipment such as pumps, refrigerators, fans, compressors, and portable drills.
What are the various types of induction?
Induction motors are classified into two types namely single phase induction motor and three-phase induction motor.
What is synchronous motor PDF?
Synchronous motor is a doubly fed. motor; three-phase power is given to. the stator while the rotor is fed from a. DC source for excitation of the field.
Why capacitor is used in single phase induction motor?
Some single-phase AC electric motors require a “run capacitor” to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly.
How many types of single phase motor are there?
What are the different types of single phase induction motors?
They are classified as follows: 1 Split-phase motor 2 Capacitor-start motor 3 Capacitor-start capacitor-run motor 4 Permanent-split capacitor (PSC) motor 5 Shaded-pole motor
What kind of induction motor is used in a refrigerator?
Single Phase Induction Motor The single-phase induction machine is the most frequently used motor for refrigerators, washing machines, clocks, drills, compressors, pumps, and so forth. The single-phase motor stator has a laminated iron core with two windings arranged perpendicularly.
How is a 1 phase induction motor similar to a squirrel cage?
1-phase induction motor is similar to a 3-phase squirrel cage induction motor in physical appearance. The rotor is same as that employed in 3-phase squirrel cage induction motor. There is uniform air gap between stator and rotor but no electrical connection between them.
How are the poles of an induction motor divided?
The poles are divided into two unequal halves. The smaller portion carries the copper band and is called as shaded portion of the pole. ACTION: When a single phase supply is given to the stator of shaded pole induction motor an alternating flux is produced. This change of flux induces emf in the shaded coil.
