A Comprehensive Guide to Home Security Systems:

This is a type of small synchronous motor.

• This motor is simple in construction and doar not required 'DC Field excitation
• Not use permanent magnet.
• It is similar to the single phase indication motor.
• Stator has main and auxiliary winding.
• Rotor basically a squirrel cage with same cut.
• Tech removed appropriate places provide desire of salient poles.
• When a stator as connected to a single phase supply the rotor start as an inside motor at the speed about 75% of syncs Speed Centrifugal Mar disconnected the auxiliary winding.

When the speed is close to Speed a a reluctance torque produce dueto the tendang of rotor to alleen it self to in in the minimum reluctance position.

• The reluctance oppose the magnetic field The magnetic line follow the lower reluctance path
• The magnetic flux which is coming from stator winding to the air the reluctance in gap and
• the reluctance more in the air gab and the reluctance
• at salient pole is less so due to the torque
• pole. The rotator align to the poles of stator having low reluctance and due to which a reluctance torque is produced and The motor runs out synchronous Speed.

Advantages:

1.  Simple construction .
2.  Easy  repair.
3. Ferry to maintenance.
4. No lose of DC winding.
5. low cost.

 Disadvantages:

1. Used for constant speed.
2. Used in machine
3. Electrical washing motor etc.
