Problems solved by technology
The existing drive motor controller is generally composed of a casing and a control circuit board installed in the casing, an IPM drive module, a driving circuit board, an electrolytic capacitor, a current sensor and a non-inductive filter capacitor. The direct current of the drive circuit board and IPM drive module causes electromagnetic interference to the low-voltage signal circuit of the control circuit board, seriously affecting the normal operation of the drive motor controller

Embodiment Construction
[0011] Such as figure 1 shown. The drive motor controller structure of the present invention includes a casing 1, an IPM drive module 2, a drive circuit board 3, an electrolytic capacitor 4, a current sensor 5, a control circuit board 6, a non-inductive filter capacitor 7, a shielding iron plate 8, and a waterproof fan 9. The interior of the shell 1 is divided into three layers: the drive circuit board 3 is welded on the IPM drive module 2 and fixed on the lower layer, which is used to convert the 154V DC high voltage through the IPM drive module 2 into a three-phase AC output according to a certain sequence; the middle layer is a shielded iron Board 8 is used to shield the interference of the lower high voltage on the upper low voltage signal, and support the upper device; the upper layer is the control circuit board 6, which is used to collect low voltage signals such as motor temperature, Hall position signal and controller current, temperature, etc., which are processed by...

The invention relates to a driving motor controller, which belongs to the technical field of new energy automobile electronic control, and mainly solves the problem that normal work of the driving motor controller is seriously influenced by electromagnetic interference of direct current voltage of a driving circuit board and an IPM driving module to a low-voltage signal circuit of a control circuit board due to the fact that the shell of the existing driving motor controller is not provided with a shielding iron plate. The driving motor controller is mainly characterized by comprising a shell, and a control circuit board, an IPM driving module, a driving circuit board, an electrolysis capacitor, a current capacitor and a non-inductive filtering capacitor which are arranged in the shell, and also comprises a shielding iron plate arranged in the middle in the shell, the driving circuit board is welded on the IPM driving module and is fixed in the shell under the shielding iron plate, and the control circuit board is fixed in the shell above the shielding iron plate. The driving motor controller has the characteristic of improving the accuracy and the output efficiency, and is mainly applied to pure electric driving motors.
Description
technical field [0001] The invention belongs to the technical field of electronic control of new energy vehicles. Specifically relates to a pure electric drive motor controller. technical background [0002] Traditional automobiles rely on the engine to burn gasoline, diesel and other fuels in the cylinder to generate power to drive the vehicle. However, in recent decades, with the increasing impact of automobile exhaust emissions on environmental pollution and climate change, and the increasing oil resources Countries are paying more and more attention to the development of new energy vehicles. In 2010, the State Council clearly listed new energy vehicles as one of the seven strategic emerging industries proposed by the country, and advocated and encouraged the production and manufacture of new energy hybrid and pure electric vehicles. . As one of the three core components of new energy electric vehicles, the design and development of the drive motor controller plays a vi...
