Embodiment Construction

[0026] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.

[0027] A motor controller and a packaging method thereof, comprising a housing 100; openings are provided on both sides of the housing 100, the two openings are respectively closed by a cover plate 130 and a water-cooling cover plate 160, and the opposite ends of the housing 100 are respectively installed There are low-voltage connectors 230 and high-voltage connectors 270. The low-voltage connectors 230 transmit low-voltage signals to the control circuit board 170. The high-voltage connectors 270 transmit the motor bus current and phase currents to the current sensor 250. The current sensor 250 will The collected current signal is transmitted to the control circuit board 170 , and the control circuit board 170 is also connected to the drive circuit board 180 . A circulating water channel is arranged in the water-cooling cover plat...

Abstract

The invention provides a motor controller and a package method thereof. The motor controller comprises a shell; openings are formed at two surfaces of the shell, and two openings are closed by using acover plate and a water-cooling cover plate; a low-voltage connector and a high-voltage connector are arranged on two opposite ends of the shell. The internal volume of the controller is compact, allspace is sufficiently utilized, and the power density of the controller is improved; since the heating of the whole controller is mainly from an IGBT module, a water channel is formed local region ofa location for mounting the IGBT module at the bottom of a controller box, on the one hand, the space of the water channel is saved, on the other hand, the heat produced in the controller can be effectively taken away, and the controller temperature is reduced. The controller radiating box structure is located in a driving system, the test shows that the structure space is extremely compact, theweight is light, and the radiating effect is good.

Description

technical field [0001] The invention relates to a motor controller and a packaging method thereof. Background technique [0002] As one of the core components of electric vehicles and hybrid vehicles, the drive motor and driver are the key to the realization of various working modes of the vehicle and directly affect the performance of the vehicle, such as vehicle fuel consumption indicators, emission indicators, power, economy and stability. Regardless of whether it is a pure electric vehicle or a hybrid vehicle, the powertrain structure is very compact, and the space left for the motor drive system is very small. While reducing the size of the motor and driver, it is also required that the motor and the controller output enough rotation speed. torque, power. [0003] In addition, for the driving motors and drivers of electric vehicles, they are usually high-voltage and high-current signals, so the heat is serious. For the heat dissipation of the driving motor and the dr...
