What Are The Types Of Micromotor Stator Core Slots?

Stators, rotors, and other components make up the majority of micromotors. The stator windings are mounted on the stator core, which is a component of the aluminum shell motor's magnetic circuit. What different stator core slot types are there then? I'll give you a little introduction now.

1. Semi-open slot: Usually used for large and medium-sized low-voltage motors; can incorporate formed windings. When a winding is said to be "formed," it can first be insulated before being inserted into a slot.

2. Semi-closed slot: This design is typically employed in small, low-voltage motors because it has a greater efficiency and power factor but more challenging wiring and winding insulation requirements.

3. Open slot: The insulation method is practical, and it is utilized for inserting and positioning forming windings. Most often, high-voltage motors employ it.

In terms of structure, the stator core of an aluminum shell motor is typically punched and laminated with a sheet of silicon steel that is 0.35 to 0.5 mm thick and has an insulating layer on the surface. Slots are punched in the inner circle of the stator in a uniform pattern to embed the stator windings.
