Problems solved by technology

[0002] At present, most of the production methods of the drive motor salient pole rotors used in electric vehicles adopt an integrated structure, such as the existing technology, patent name: brushless electromagnetic and permanent magnet hybrid voltage stabilizing power generation device for electric vehicle range extender, patent number: ZL201610306601.4 discloses the following technical scheme, which consists of a front end cover, a rear end cover, a hybrid rotor, a stator, and an electronic voltage regulator controller. In the arc-shaped slot, the electric excitation winding is wound on the T-shaped salient pole. The motor rotor with such an integrated structure limits the wire diameter and the number of winding turns of the excitation winding. It is difficult to wind the coil, the processing technology is complicated, and the cost of the motor is reduced. High, and the magnetic pole is provided by a single magnetic steel magnetic field, the performance of the motor is not stable enough

Abstract

The invention provides a method for producing a radially forked segmented salient pole rotor for a driving motor, which belongs to the technical field of automobile motors and electrical appliances. The production method of radial fork-in segmented salient pole rotor for drive motor includes the production steps of yoke rotor core and T-shaped rotor core. The yoke rotor core adopts salient pole tooth groove structure, which has high mechanical strength and reliability. Strong; the salient pole rotor is radially forked into the segmented T-shaped rotor core, and the electric excitation winding is not limited by the limited space between adjacent pole pieces. The off-line winding is easy to machine operation, convenient and fast. Winding in the same direction, high production efficiency; using three parallel magnetic fields, the total reluctance of the magnetic circuit is small, and the magnetic force line of electric excitation passes through the silicon steel sheet, so the iron loss is small.

Description

technical field [0001] The invention provides a method for producing a radially forked segmented salient pole rotor for a driving motor, which belongs to the technical field of automobile motors and electrical appliances. Background technique [0002] At present, most of the production methods of the driving motor salient pole rotors used in electric vehicles adopt an integrated structure, such as the existing technology, patent name: brushless electromagnetic and permanent magnet hybrid voltage stabilizing power generation device for electric vehicle range extender, patent number: ZL201610306601.4 discloses the following technical scheme, which consists of a front end cover, a rear end cover, a hybrid rotor, a stator, and an electronic voltage regulator controller. The tile permanent magnet steel is installed on the T-shaped salient pole of the rotor core In the arc-shaped slot, the electric excitation winding is wound on the T-shaped salient pole. The motor rotor with this...
