Shaded pole motor saves energy and reduces consumption

2020/08/17

        Energy saving and consumption reduction is the theme of today's world, and metal raw materials such as iron and copper are non-renewable resources. Therefore, these raw materials should be saved and reduced in the production design process. Shaded pole motors are widely used in ventilation circulation systems for heating and cooling household appliances due to their simple structure and high reliability. Taking into account the particularity of the structure of the shaded pole motor, combined with the actual situation of the production process, the electromagnetic design and structural design of the motor are optimized, so that the final cost performance of the motor can be improved, the consumables are reduced, and social resources are saved. At the same time, it reduces the cost of the motor, enhances its competitiveness among similar products, and brings certain economic benefits.

      The structure of the ordinary shaded pole motor, the motor is a salient pole structure, using concentrated windings, short-circuit windings are welded on one side of the convex magnetic poles, usually called short-circuit rings. By reducing the short-circuit ring stator end face, the number of motor coil turns remains unchanged. However, the length of each turn is shortened, which reduces the coil resistance, and the copper loss of the motor is slightly reduced. The length of the short-circuit ring is shortened, which increases the current of the short-circuit winding and the temperature rise of the motor. The performance remains basically unchanged, and there is a slight advantage.
