What  are the Advantages and Disadvantages of Induction Motor?

Induction Motor Definition

An induction motor is defined as an electric motor that operates on alternating current (AC) and uses electromagnetic induction to generate motion.

Simple Construction

Induction motors have a simple and robust construction, making them reliable and low maintenance.

Advantages of Induction Motors

• Simple structure and easy maintenance

• Environmentally resistant, robust and mechanically strong

• Low cost of motor

• It does not produce sparks and can be used safely under dangerous conditions

• Three-phase induction motor has high starting torque, good speed regulation and reasonable overload capacity

• Induction motor efficiency is high, full load efficiency range of 85% to 97%

Disadvantages of Induction Motors

• The single-phase induction motor has no self-starting torque and requires auxiliary equipment to start the single-phase motor

• The speed control of induction motor is very difficult to achieve

• The high input surge current of the induction motor causes the voltage to drop when starting the motor

• Due to the difference in starting torque, the motor cannot be used in applications requiring high starting torque

Efficiency Range

Induction motors are highly efficient, with efficiency rates ranging from 85% to 97%.
