[0004] In the current switched reluctance motor, it is necessary to provide continuous and stable working current to the coil to realize the stable operation of the motor, but inside the motor, the current working power supply circuit lacks the function of feedback detection, so when the output voltage fluctuates At this time, the fast and effective adjustment cannot be performed very well, thereby reducing the stability of the motor's work; not only that, but in the process of motor rotation, the speed of the motor needs to be monitored in real time, but in the existing speed detection circuit, In order to detect and collect multiple information, multiple detection circuits are required, which greatly increases the production cost of the motor and reduces its practical value

Abstract
The invention relates to a switched reluctance motor used for a new energy automobile. The switched reluctance motor comprises a rotor, a stator and three driving mechanisms. A driving assembly comprises a center control unit. The center control unit comprises a working power supply module and a rotation speed measurement module. The working power supply module comprises a working power supply circuit. The rotation speed measurement module comprises a rotation speed measurement circuit. According to the invention, in the working power supply circuit, the constant voltage is kept on a fourth resistor form the output to a feedback passage of inverted input of an operation amplifier, so the power supply circuit is allowed to output stable working current, stable and reliable driving can be performed on parts of elements in the motor, and the working reliability of the motor is improved. In addition, in the rotation speed measurement circuit, the type of an integrated circuit is LM339 and is a voltage comparator chip, and four independent voltage comparators are installed therein, so measurement of multiple paths of signals can be achieved, cost of signal measurement is reduced and market competitiveness of the motor is improved.
Description
technical field [0001] The invention relates to the field of switched reluctance motors, in particular to a switched reluctance motor used in new energy vehicles. Background technique [0002] Switched reluctance motor is a new type of speed regulation motor. The speed regulation system has the advantages of both DC and AC speed regulation systems. It is the latest generation of stepless speed regulation system following the frequency conversion speed regulation system and brushless DC motor speed regulation system. It has simple and firm structure, wide speed regulation range, excellent speed regulation performance, high efficiency in the whole speed regulation range, and high system reliability. It mainly consists of four parts: switched reluctance motor, power converter, controller and position detector. The controller contains the power converter and control circuit, while the rotor position detector is installed at one end of the motor. [0003] Nowadays, the applicat...
