Embodiment Construction

[0056] The present invention is related to the stator structure of the vehicle-mounted drive motor. It strengthens the structural strength of the stator core assembly 300 made of laminated original electric steel plates, and uses soft magnetic powder for the motor core to improve the bonding force with the casing. (SMC) iron core 310, 50 replaces the stator plate 320 generally made of stainless steel, and plays the role of the stator plate. The soft magnetic powder (SMC) stator plate is consistent or similar to the iron core with optimized electromagnetic characteristics, and the height of the motor Consistently, the structure of the present invention can improve motor performance by increasing the effective core height in relation to motor performance.

[0057] Figure 5 It is an exploded view of a general motor. The motor 200 is pressed into the stator assembly 220 on the casing 210. The rotor assembly composed of the rotor core 230 and the rotor shaft 240 is supported by th...

Abstract

The present invention relates to a stator assembly of a driving motor for a vehicle including a core (321); stator plates (322) attached to both sides of the core; an insulator inserted into the core and the stator plate; and a coil surrounding the core. The core (321) is made of a plurality of laminated electrical steel plate. The stator plate (322) is made of soft magnetic composites (SMC).

Description

technical field [0001] The present invention relates to a stator assembly of an onboard drive motor, in particular to a stator assembly having a stator disc made of soft magnetic powder (SMC). Background technique [0002] From the electromagnetic point of view, the structure of the motor is a functional part, such as figure 1 As shown, it is composed of an iron core 110 , a coil 120 and an insulator 130 . [0003] The coil 120 forms a circuit and acts as a source of magnetomotive force. The iron core 110 forms a channel for the magnetomotive force (magnetic flux). Here, it is recommended to use a material with low reluctance that can make the magnetic flux flow quickly. [0004] In addition, the insulator 130 is located between the coil and the iron core 110 for electrical insulation, ensuring that the current from the power source only flows in the coil, and the iron core or the motor structure will not leak, thereby improving the performance of the motor and preventing e...
