Embodiment Construction

[0023] Turning now to the drawings, Figure 1 is a cross-sectional view of a first embodiment of the present invention. As can be seen in this figure, the disc motor assembly generally indicated by the numeral 10 includes a disc rotor assembly 20 and a stator assembly 30. The disc rotor assembly includes a central disc member 21, which is mounted on a mounting shaft 40 through a standard low-friction bearing 22. The shaft 40 is fixed on the frame (not shown) of the vehicle and serves as a mounting support for the disc motor assembly 10. For example, the axle 40 may include the axle head of an automobile. A plurality of permanent magnets 25i are fixed on the two opposite surfaces of the disc 21. The disc member 21 is made of non-magnetic material, such as Delrin (polyoxymethylene resin), nylon, aluminum or any other harder non-magnetic material. One of various known techniques can be used to fix the permanent magnet 25i on both sides of the disc member 21, such as bonding with a cur...

Abstract

The invention relates to a multi-phase alternative-current vehicle motor, which comprises one or more disc rotors and relative stators, wherein each rotor has one disc and several permanent magnets arranged in one or several circle tracks of rotor; each stator has relative polar sheets and windings along the mounting plate in relative circle track; the disc is rotationally mounted on supporters; and the stator is fixed on supporter.

Description

Technical field [0001] The invention relates to a multi-phase AC motor for driving a vehicle. The present invention particularly relates to a multi-phase AC vehicle drive motor with compact design and improved torque. Background technique [0002] Multiphase AC vehicle drive motors are known, and they are used to drive many different types of vehicles, such as bicycles, motorcycles, automobiles, and small trucks. A typical motor design has a rotor and a stator. The rotor is fixedly connected to the wheel of the vehicle so as to rotate together with the wheel. The rotor is also provided with a plurality of permanent magnets, which are installed around the circumference of the rotor in a predetermined magnetic direction. The stator is fixedly installed on the frame and has a plurality of electromagnets, which are distributed close to the permanent magnets of the rotor. The coil of the electromagnet is connected to a multi-phase AC drive circuit, which is usually three-phase or Y-sh...
