Embodiment Construction
[0016] The structure of the present invention will be explained in detail below in conjunction with the accompanying drawings.
[0017] Such as figure 1 As shown, a switched reluctance motor controller provided by the present invention includes a control circuit module, a power conversion module, and a drive current module connected in sequence, wherein the output end of the power conversion module is also connected to a position detection pulse module; The switched reluctance motor controller also includes a non-power output phase current detection module and a rotational speed / rotation acceleration calculation module, and a position estimation module is connected between the non-power output phase current detection module and the control circuit module. During the use of the switched reluctance motor controller, it only needs to be installed on the electric bicycle (connected between the vehicle controller and the switched reluctance motor), that is, the control circuit modu...

The invention discloses a switched reluctance motor controller and a control method of the switched reluctance motor controller. The switched reluctance motor control method includes the first step of receiving an instruction, the second step of converting power, the third step of outputting drive current to a switched reluctance motor, the fourth step of sending position detection pulse to the switched reluctance motor, the fifth step of detecting non-power output phase current from the switched reluctance motor, the sixth step of estimating the position of a rotor of the switched reluctance motor, the seventh step of sending the position information of the rotor of the motor to a control circuit module of the switched reluctance motor, the eighth step of calculating the rotation speed and the accelerated rotation speed of the switched reluctance motor and the ninth step of sending information of the rotation speed and the accelerated rotation speed of the switched reluctance motor to a vehicle controller. The switched reluctance motor controller and the control method of the switched reluctance motor controller have the advantages that the switched reluctance motor can be controlled effectively, the motor is simple in structure and high in economical efficiency and reliability, and vehicle control is optimized.
Description
technical field [0001] The invention relates to the technical field of controllers, in particular to a switched reluctance motor controller and a control method thereof. Background technique [0002] With the rapid development of modern cities in my country, the scale of cities continues to expand, the level of urbanization increases rapidly, and the construction of new countryside accelerates. The disposable income of urban and rural residents is increasing, and the radius of people's activities is extending. The existence of public transportation cannot solve the last mile. However, the increasingly congested roads have restricted the growth of the number of cars. Although fuel motorcycles have the advantages of being convenient to use as a means of transportation, [0003] However, with the increase in the number of fuel motorcycles in cities, the problems of environmental pollution, fuel consumption and energy have become increasingly prominent. The development of fuel mo...
