Insulating framework and motor

Abstract

The invention relates to an insulating framework and a motor using the insulating framework, and the insulating framework comprises a main body annular part and N hollow insulating cylinders which are uniformly arranged in the circumferential direction of the outer side of the main body annular part and extend in the radial direction, one end, far away from the main body annular part, of the hollow insulating cylinder is provided with an end part separation blade protruding out of the peripheral surface of the hollow insulating cylinder, wherein N is an integral multiple of the phase number n of the motor. The motor comprises a stator and an outer rotor which is coaxially arranged with the stator and is located on the outer side of the stator, and the stator is provided with the insulating framework and an iron core sealed in the hollow insulating cylinder. According to the insulation framework, insulation paper is not used in the process, the production process is simplified, meanwhile, the insulation performance of the stator is improved, the height of the stator is reduced, the matched outer rotor is matched, the height of the motor is reduced, the volume power is improved, and the actual installation requirement is met.

Description

Technical field [0001] The present invention relates to the field of motor technology, and more particularly to an insulating skeleton and a motor having the insulating skeleton. Background technique [0002] The power unit of the motor as the rotating member is widely used in the field of various types of household appliances. On the pumping hood, the indoor fumes are driven out of the room by permanent magnet synchronous inverter motor, and the electrical miniaturization is compressed by the electrical installation. Space, for this purpose, it is necessary to develop a small size high-power motor product. [0003] The existing motor products are all magnetic fields that have changed from the coil on the core, thereby driving the rotor rotation. In order to avoid the core to lead to energy loss, heat increase brings potential safety risks, which generally achieves insulation on the core between the iron core and the coil, so that the winding process complicates, the winding proc...

AI Technical Summary

Problems solved by technology

In order to avoid potential safety risks caused by energy loss and increased heat generation caused by the iron core, insulating paper is usually laid between the iron core and the coil to insulate the iron core during production, which complicates the winding process. During the winding process, The insulating paper may be folded, shifted, and the insulation effect is reduced, and the wrong use method may cause the insulation of the insulating paper to fail. Both of the above two points will bring potential safety risks
