Week 3 Session 7

1)INDUCTION MOTOR:

Induction motors are considered the most cost-effective and reliable ones in the industry. The control of these motors is quite simple to implement. Because of their simple design, induction motors don’t require high maintenance.

2)SYNCHRONOUS MOTOR:

In synchronous motors, the rotor turns at the same speed as that of the rotating magnetic field, unlike an induction motor where it turns at a lower speed than that of the field. PM motors offer an array of advantages of induction motors including higher efficiency, high torque and power density, high torque at low speed, and compact and low weight.

3)BRUSHED DC MOTOR:

Brushed DC motors are widely used in electric vehicles for retracting, positioning, and extending electrically-powered side windows. These motors are suitable for many uses because of their low cost. However, the commutators and brushes tend to wear relatively quickly because of their continued contact, leading to periodic maintenance and frequent replacement.

4)BRUSHLESS DC MOTOR:

BLDC motor doesn’t use brushes and employs an electronic commutator instead, which increases its efficiency and reliability by eliminating the source of power and wear loss. In addition, these motors boast of some significant advantages over induction motors and brush DC motors like higher speed ranges, noiseless operation, faster dynamic response
