Problems solved by technology

In order to prevent the winding wire from touching the rotor 4, the flying wire of the winding wire needs to be kept very long, that is, the end of the coil is long, and this part produces a large loss, which affects the effect of the motor

Embodiment Construction

[0022] The rotor, the stator and the winding structure of the induction motor of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0023] Such as image 3 As shown, the rotor, stator and winding structure of the induction motor include an inner rotor 4, a stator 17 is arranged outside the inner rotor 4, and an outer rotor 13 is arranged outside the stator 17, wherein the inner periphery of the stator 17 and the outer There are winding slots 14 on the periphery, and the winding wires only pass through the winding slots 14 between the inner and outer periphery of the stator 17 to form the main winding group 20 and the secondary winding group 21 . This winding structure avoids increasing the length of long flying wires in order to prevent the winding wires from touching the rotor, and reduces the waste of copper wires. Moreover, this winding structure forms two independent magnetic circuits, which minimizes the w...

Abstract

This invention discloses a rotor, a stator and a winding structure of an induction-motor including an inner rotor, a stator set at the outside of the inner rotor and an outer rotor set at the outside of the stator, among which, the internal and external peripheries of the stator are opened with winding slots and the winding is formed by passing through the slots between the peripheries, a tooth part cast with Al is formed on the inner rotor and through holes cast with Al are formed on the outer rotor, both of the rotors rotate to a same direction and are connected to a same cylinder when the compressor is a cylinder.

Description

technical field [0001] The present invention relates to an induction motor. In particular, it relates to a rotor, a stator and a winding structure of an induction motor with less magnetic flux loss and good load capacity. Background technique [0002] figure 1 It is a cross-sectional schematic diagram of the internal structure of the hermetic compressor. Such as figure 1 As shown, the upper case 1t and the lower case 1b constitute the closed case 1 . The inside of the closed casing 1 is provided with a frame 2 . A motor stator 3 is fixed on the frame 2 . The frame 2 is supported inside the closed case 1 by springs 2S. [0003] A shaft 5 runs through the center of the frame 2 . A motor rotor 4 is integrally formed on the shaft 5 . The rotor 4 rotates together with the shaft 5 by electromagnetic interaction with the stator 3 . [0004] On the upper end of the crankshaft 5, an eccentric member 5b is formed eccentrically with respect to the rotation center of the cranks...
