Overview

Induction motor

Induction motor refers to a type of motor that uses electromagnetic induction between the stator and rotor to induce current within the rotor to achieve electromechanical energy conversion. The stator of an induction motor consists of three parts: the stator core, stator winding, and frame.
The rotor is composed of a rotor core, rotor winding, and shaft. The rotor core is also a part of the main magnetic circuit, usually composed of 0.5mm thick silicon steel sheets stacked together, and the core is fixed on the shaft or rotor bracket. The outer surface of the entire rotor is cylindrical. The rotor winding is divided into two types: cage type and winding type.

Under normal circumstances, the rotor speed of an induction motor is always slightly lower or slightly higher than the speed of the rotating magnetic field (synchronous speed), so an induction motor is also known as an "asynchronous motor".

When the load of an induction motor changes, the speed and slip of the rotor will change accordingly, causing corresponding changes in the electromotive force, current, and electromagnetic torque in the rotor conductor to meet the needs of the load. According to the sum of the positive and negative slip rates, induction motors have three operating states: electric motor, generator, and electromagnetic braking.

Characteristics of Induction Motors

1. Induction motors not only use auxiliary coils and capacitors during start-up, but also during operation. Although the starting torque is not very high, it has a simple structure, high reliability, and high efficiency.

2. It can operate continuously.

3. The rated speed of the motor will also change with the size of the load.

4. Used in applications that do not require speed braking.

5. Use E insulation levels, while UL motors use A levels.

6. There are two types of induction motors: single-phase induction motors and three-phase induction motors.

7. The single-phase motor is an induction motor with high efficiency and low noise.

8. When a single-phase induction motor operates, it generates torque opposite to the direction of rotation, so it is impossible to change direction in a short period of time. The rotation direction of the motor should be changed after it has completely stopped.

9. The power supply of single-phase motor includes A (110V 60Hz), B (220V 60Hz), C (100V 50/60Hz), D (200V 50/60Hz), E (115V 60Hz), X (200-240V50Hz), etc.

10. The power supply of three-phase motor includes U (200V 50/60Hz), T (220V 50/60Hz), S (380-440V 50/60Hz), etc.
The rotor in an induction motor does not have a specific electrical connection.
