Description

Technical Field

[0001] This utility model relates to the field of automotive motor technology, specifically to a water-cooled dual-source integrated motor. Background Technology

[0002] Currently, a dual-source motor for steering systems in new energy vehicles is available on the market. Its principle involves a single motor stator containing two sets of windings: a high-voltage winding and a low-voltage winding. The high-voltage winding is connected to the vehicle's power battery, while the low-voltage winding is connected to the low-voltage battery. When the vehicle's high-voltage system malfunctions and cannot provide power steering, the low-voltage power supply is activated to provide short-term emergency power steering. However, this type of integrated permanent magnet motor currently faces the following unresolved technical problems: 1. Large size and high cost; 2. Poor heat dissipation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water-cooled dual-source integrated motor, which has a simple structure, small size, low manufacturing cost and good heat dissipation effect.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A water-cooled dual-source integrated motor includes a middle housing, a front cover, and a rear cover. The front cover and the rear cover are respectively fixed to the front and rear ends of the middle housing. A low-voltage controller is fixed to the outer end of the rear cover. Water channels are distributed along the annular shape of the middle housing. Grooves are also distributed between adjacent water channels on the left and right sides of the middle housing along the annular shape. A spliced ​​stator is installed inside the middle housing. The spliced ​​stator is composed of at least two spliced ​​stator assemblies that are interlocked and locked together along the annular shape. The spliced ​​stator assembly includes a frame and a stator core integrally molded with the frame. Low-voltage windings and high-voltage windings are also wound on the frame.

[0006] A further technical solution is that the low-voltage controller is also equipped with a low-voltage winding input terminal and a high-voltage winding input terminal, the ports of which are used to connect to the vehicle.

[0007] A further technical solution is that the rear cover is also provided with through holes, through which the lead wires of the low-voltage winding and the high-voltage winding on the splicing stator assembly pass and enter the low-voltage controller. The lead wires of the low-voltage winding are connected to the low-voltage controller, while the lead wires of the high-voltage winding are connected to the input terminal of the high-voltage winding.

[0008] A further technical solution is that a partition is distributed on the frame, between the low-voltage winding and the high-voltage winding, to separate the low-voltage winding and the high-voltage winding.

[0009] A further technical solution is that the frame is also provided with protrusions and slots on the outer end of the frame. The protrusions and slots on adjacent frames are spliced ​​together along the ring to form a spliced ​​stator as shown in Figure 2.

[0010] The beneficial effects of this utility model are:

[0011] This utility model discloses a water-cooled dual-source integrated motor. The middle housing has water channels distributed in a ring, and the water channels are interconnected, which can effectively dissipate heat from the motor and improve the heat dissipation effect. At the same time, the spliced ​​stator is composed of at least two spliced ​​stator components that are interlocked and locked together in a ring. High and low voltage windings are wound on the spliced ​​stator components. The stator core and frame adopt an integrated injection molding structure, which can reduce the overall stator volume and reduce production costs. Attached Figure Description
