On the Structural Features and Applications of the Q Motor

The structure of the motor has two poles. It consists of a stator and a rotor. The rotor is of the cage type, and the stator includes the main poles, also known as protruding poles. These main poles are equipped with power supply winding that form the primary winding of the motor. The poles are divided into two unequal parts. The smaller part contains copper strips, also known as shielding coils. This shielding coil is located on the smaller part of the pole and is called the shielding pole. It plays a crucial role in the operation of the motor.

Q motors operating with alternating current voltage are usually used in low-power applications. They are typically designed for single-phase alternating current power supply and are most suitable for continuous operation with low starting torque. The main features include:

Voltage range: They usually operate at standard alternating current voltages, such as 120V or 240V, making them compatible with a wide range of applications.

Applications: They are used in small fans, blowers, range hoods, and other ventilation systems that require low power and continuous operation.

The Q motor starting torque generated is equivalent to half of the full-load torque.

Due to the power loss in the shading coil, the efficiency is relatively low.

Depending on the position of the shading coil, the rotation direction is different.

Simple design: The structure of the Q motor is simple, with few moving parts, high reliability, and easy maintenance.

Low cost: Due to the simple design, these motors are one of the most cost-effective choices, and are suitable for applications with budget constraints.

Compact size: Q motors have a small footprint and can be used in environments with limited space, while large motors are impractical in such environments.

Quiet operation: Q motors operate quietly, which is crucial for household appliances and small ventilation systems.
