Stator core and motor

Abstract

The invention provides a stator core and a motor. The stator core comprises an external yoke iron core (1) and an internal yoke iron core (2), wherein the external yoke iron core (1) is provided with an internal hole (3), and the internal yoke iron core (2) is embedded in the internal hole (3) of the external yoke iron core (1). The length and width of the internal yoke iron core (2) are not equal, and a main winding duct is formed between the width direction of the internal yoke iron core (2) and the external yoke iron core (1). The stator core provided by the invention can reduce the consumption of enamelled wires, and saves the cost.

Description

technical field [0001] The invention relates to the technical field of motor equipment, in particular to a stator core and a motor. Background technique [0002] At present, there is an increasing demand for high-speed and low-power fan motors in the market, while traditional motors are mostly full-circle multi-slot structures, with complicated processing procedures and high costs. In addition, since the high-speed fan requires the motor speed to be above 2000 rpm, the traditional four-stage motor has a synchronous speed of 1500 rpm, so it cannot meet its high speed requirement, and a two-stage structure must be used. The existing iron core has 16 slots, which is suitable for four-level motors. If the second-level wiring is carried out on this iron core, large and small circles or other wiring methods must be used. The use of enameled wires such as copper wires is relatively heavy, resulting in increased costs. Contents of the invention [0003] In view of this, the objec...

Problems solved by technology

[0002] At present, the demand for high-speed and low-power fan motors in the market is increasing, while traditional motors are mostly full-circle multi-slot structures, with complicated processing procedures and high costs

In addition, because the high-speed fan requires the motor speed to be above 2000 rpm, the traditional four-stage motor has a synchronous speed of 1500 rpm, so it cannot meet its high speed requirements, and a secondary structure must be used

The existing iron core has 16 slots, which is suitable for four-stage motors. If two-level wiring is carried out on this iron core, large and small circles or other wiring methods are required. The weight of enameled wires such as copper wires is relatively large, resulting in increased costs.
