Detailed description of the invention
In order to have a clear understanding of technical scheme, its detailed structure be will be set forth in the description that follows.Obviously, the concrete also deficiency of implementing of the embodiment of the present invention is limited to the specific details that those skilled in the art is familiar with.The preferred embodiments of the present invention are described in detail as follows, in addition to these embodiments described in detail, it is also possible to have other embodiments.
Below in conjunction with embodiment, the present invention is described in further details.
A kind of control system based on New energy automobile motor; described control system includes control device, protection device, second switch; described control device electrically connects described second switch; described second switch electrical connection motor; described protection device is arranged on the outside of described second switch, and is provided with lock in described protection device.Described control system includes control device, second switch and protection device；Described control device connects described second switch；Described second switch connects motor；Described second switch is arranged on inside described protection device; to prevent described second switch to be misused; described control system includes the sensor of a detection-sensitive motor rotor position information; receive the signal of described sensor sensing and according to the processor of this signal estimation electrical angle; and generate for controlling the control signal generation module that motor runs according to described electrical angle, described protection device is compared amplifying circuit, preposition by signal
