Embodiment Construction

[0071] The present invention is described in detail below in conjunction with accompanying drawing:

[0072] figure 1 It is a schematic structural diagram of the outer rotor stator double-winding AC motor system with cage barrier assembly of the present invention. The system mainly includes a stator 1, an outer rotor 2, and a bidirectional inverter 3, wherein three-phase symmetrical power windings 5 ​​and 2q of 2p poles are placed on the stator 1 The three-phase symmetrical control winding 6, the number of poles of the power winding 5 and the number of poles of the control winding 6 can also be interchanged, but they all satisfy 2p-2q≥4, which can realize the maximum electromagnetic coupling of two sets of stator windings with different pole numbers . The power winding 5 is connected to the grid 4, the control winding 6 is connected to one end of the bidirectional inverter 3, and the other end of the bidirectional inverter 3 is connected to the grid. The control winding 6 is...

Abstract

The invention relates to a cage barrier spliced outer rotor stator double-winding alternating current motor. The motor is characterized in that an outer rotor is arranged outside a stator, a three-phase symmetry power winding and a control winding are arranged in slots on the surface of the outer side of the stator, and the same cage outer rotor modules are connected with a sleeve through outside positioning slots and spliced in a circumferential direction to form the outer rotor with salient pole types; the inner surface of each cage barrier outer rotor module is provided with radial trapezoid-shaped slots which have multiple different step slot widths, and short circuit cage bars are arranged in the slots; after the adjacent rotor modules are spliced, common trapezoid-shaped slots are formed on connection parts and have multiple different step slot widths along a radial direction, gaps of the bottoms of the slots reach the inner surface of the sleeve, and common cage bars are arranged in the slots; and the invention aims to provide the novel cage barrier combined outer rotor stator double-feed alternating current motor which is convenient to process and manufacture, ensures that the coupling capacity of two windings of the stator is optimized, and has the high power density and the excellent steady state and dynamic performance.

Description

Technical field: [0001] The invention relates to an AC motor, in particular to a cage-barrier-assembled outer-rotor-stator double-winding AC motor and a control method thereof. The motor can be operated as a motor or as a generator. Background technique: [0002] Cage assembly outer rotor stator The stator of the double-winding AC motor includes three-phase symmetrical power windings with 2p poles and three-phase symmetrical control windings with 2q poles (or three-phase symmetrical power windings with 2q poles and three-phase symmetrical control windings with 2p poles ), and satisfy 2p-2q≥4, the coupling between two sets of windings is by p r =p+q is implemented with a specially designed rotor for the poles, so the rotor structure of this type of motor will have an important impact on the steady-state performance, dynamic characteristics and power density of the motor. The rotor structures that can be used for this type of motor mainly include two types: wound type and re...
