Abstract

The invention relates to a brushless double closed-loop switched reluctance motor controller with a position sensor, applicable to rail-free electric traffic tools and rail-bound electric traffic tools. A digital logic circuit and a micro control unit (MCU) are integrated in a chip of a system-on-chip, and the hardware circuit of a digital part is designed into software so as to achieve the purpose of simplifying a digital hardware circuit. Separated IGBT power electronic power devices are adopted, various complex electric drive loads are designed in a personalized way, and under-voltage, over-current, overheating and short-circuit protection circuits are designed in a tailored way from an overall perspective of the switched reluctance motor controller. Counter electromotive force produced by a switched reluctance motor (SRM) in operation is better converted by a bootstrap circuit into energy for motor operation, so that the performance of the switched reluctance motor controller is improved from the aspects of safety and stability.

Description

Technical field

[0001] The technical invention relates to a brushless double closed-loop switched reluctance motor (SRM) control system with a position sensor for a trackless electric vehicle and a tracked electric vehicle. Among them, trackless electric vehicles include electric vehicles, electric cars, electric buses, etc.; tracked electric vehicles include subways, high-speed rails, and bullet trains. Background technique

[0002] Under the pressure of environmental pollution, green transportation has become the main theme of people's travel, travel, transportation and other tools. In order to adapt to this change in the living environment, electric transportation has become an ideal choice for people. Because the switched reluctance motor (SRM) has a simple and sturdy structure, easy maintenance, large torque and low current at start-up and low speed, wide range of high-speed constant power, and strong fault tolerance, and the rotor of the switched reluctance motor (SRM)...
