Problems solved by technology

[0002] Electric vehicles are gradually popularized due to their advantages of energy saving and environmental protection. However, the current drive motors use high-energy-consuming three-phase asynchronous motors and permanent magnet synchronous motors with iron cores. Silicon steel sheets with high magnetic permeability are laminated to form iron cores. , the existence of the iron core leads to problems such as large volume, heavy weight, large loss, large vibration and noise, and high cost.

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the present invention will be further described, as figure 1 The shown permanent magnet coreless motor for electric vehicles is characterized in that: two outer rotor discs (1), one motor middle rotor disc (3), two stator armatures (7), two stator armatures Pivot plate (4), permanent magnet (2) and bearing (6), shaft (5) and motor housing (8), the motor rotor consists of two outer rotor discs (1) and one middle rotor disc (3).

[0018] The motor casing (8) and the three rotor disks are all made of aluminum alloy, and the permanent magnet (2) is fixed on the rotor aluminum disk by bonding and steel wire welding. Since the motor rotor It is also a part of the motor casing (8), which is used as the hub of the automobile motor, thus avoiding the eddy current loss caused by the mutual movement of the permanent magnet (2) and the motor casing (8), and the shaft (5) is fixed on the motor through the bearing (6) On the rotor, the...

Abstract

The invention provides a permanent magnet non-iron-core outer rotor motor used for an electric vehicle. The permanent magnet non-iron-core outer rotor motor used for the electric vehicle includes twoouter side rotor disks, a motor intermediate rotor disk, two stator armatures, two stator armature disks, a permanent magnet, a bearing, a shaft and a motor shell. A motor rotor consists of the two outer side rotor disks and one intermediate rotor disk. The motor shell and three rotor disks are made of aluminum alloy. An iron core structure of the rotor and a stator is removed, which greatly reduces weight of the motor. The stator and the rotor adopt a non-iron-core structure and are connected in series to ensure performance of the motor. The non-iron-core motor is made without a silicon steelsheet, and the rotor is directly used as a hub of the electric vehicle, which greatly reduces the weight of the motor, and improves efficiency of the motor, and simultaneously motor vibration, noisesand cost are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a permanent magnet ironless motor for electric vehicles. Background technique [0002] Electric vehicles are gradually popularized due to their advantages of energy saving and environmental protection. However, the current drive motors use high-energy-consuming three-phase asynchronous motors and permanent magnet synchronous motors with iron cores. Silicon steel sheets with high magnetic permeability are laminated to form iron cores. However, the existence of the iron core leads to problems such as large volume, heavy weight, large loss, large vibration and noise, and high cost. Contents of the invention [0003] According to the deficiencies in the prior art, the present invention provides a permanent magnet ironless motor for electric vehicles. The rotor and stator of the motor adopt the structure of removing the iron core, so that the mass of the motor is greatly r...
