Problems solved by technology

The connection process leads to serious current loss and slow signal response
The motor casing needs to be provided with a connection hole. When the electric vehicle is wading through water, the connection hole is easy to seep into the motor, which is a safety hazard.
The existing controller is installed inside the protective casing, which has poor heat dissipation effect, shortens the service life of power tubes and other electronic devices, and has low working efficiency

Embodiment 1

[0029] This preferred embodiment provides a motor system. like Figure 1 to Figure 5 As shown, the motor system includes a motor 10 and a controller 20 , and a connector 18 is provided between the motor 10 and the controller 20 . The motor 10 includes two side covers, wherein the first side cover 11 is recessed inward to form a recess 111 . The motor shaft 8 of the motor 10 passes through the recess 111 ; the controller 20 is mounted on the motor shaft 8 and located in the recess 111 .

[0030] The controller 20 is set in the concave portion 111 formed by the recessed side cover of the motor 10, and then connected through the connector 18, which shortens or even cancels the connection line originally connected between the controller 20 and the motor 10, reduces current consumption, and improves The reaction speed of the control signal is improved; the risk of water seepage into the motor 10 from the position of the connection hole is reduced; the space of the whole vehicle i...

Embodiment 2

[0038] This preferred embodiment provides a motor system whose structure is basically the same as that of the first preferred embodiment. The motor system includes a motor and a controller, a connector is provided between the motor and the controller, the motor includes two side covers, wherein the first side cover is recessed inward to form a recess, and the motor shaft of the motor passes through the recess; the controller is installed on on the motor shaft and located in the recess.

[0039] The difference is that a gap can be formed between the controller shell and the outer side wall of the recess, and they can also be close together, which does not affect the invention purpose of shortening or even canceling the connection and reducing the current consumption. The MOSFET and the PCB board can be arranged in parallel or vertically, as long as the internal space of the controller can accommodate the MOSFET. The MOSFET can be placed on the inner wall of the side cover of t...

Embodiment 3

[0041] This preferred embodiment provides an electric vehicle, which is provided with the motor system as described in the first or second preferred embodiment. The setting position of the motor system is not limited, and it can be set on the vehicle frame of the electric vehicle, and can also be set on the driving wheel of the electric vehicle.

Abstract

The invention discloses a motor system and an electric vehicle and belongs to the field of electric vehicles and accessories, wherein the motor system and the electric vehicle are designed to solve the problem that current loss of existing devices is high. The motor system comprises a motor and a controller, a connector is arranged between the motor and the controller, the motor comprises two side covers, the first side cover is concave inwards to form a concave portion, a motor shaft of the motor penetrates through the concave portion, the controller is installed on the motor shaft and is located in the concave portion, the controller comprises a controller shell, and an annular seam is formed between the controller shell and the outer side wall of the concave portion. The electric vehicle is provided with the motor system. According to the motor system, a connection line is shortened or even omitted, current loss is reduced, the reaction speed of control signals is improved, energy is saved, efficiency is high, waterproof performance is good, installation is convenient to achieve and cost is low. The electric vehicle is provided with the motor system, space of the whole vehicle is saved, the integration level is high, the work state is stable, cost is low and assembling efficiency is high.

Description

technical field [0001] The invention relates to a motor system and an electric vehicle provided with the motor system. Background technique [0002] Electric vehicles need to be equipped with a motor and a controller, and the controller is connected to the motor through wires to transmit various signals. [0003] The existing motor and the controller are two independent devices arranged separately, and the connection line is usually relatively long. The connection process leads to serious current loss and slow signal response. A connection hole needs to be provided on the motor housing. When the electric vehicle is wading through water, the connection hole is prone to water seepage into the motor, which is a potential safety hazard. The existing controller is installed inside a protective casing, which has poor heat dissipation effect, shortens the service life of electronic devices such as power tubes, and has low working efficiency. Contents of the invention [0004] ...
