Embodiment Construction
[0045] According to the specific experiments and combined Figure 4 , the present invention will be further described.
[0046] The experimental prototype uses a 12 / 8-pole three-phase switched reluctance motor with a rated power of 4kW and a rated speed of 2200rpm.
[0047] Microcontroller 1 uses single-chip microcomputer STM32F103RBT6, and C1, C2, and C3 use voltage-type Hall current sensors, which can transmit three-phase current signals to the single-chip microcomputer. The single-chip microcomputer converts the analog signal into a digital signal through the A / D conversion module for internal program processing. The position detection unit is composed of the rotor position measurement tooth plate, three slot-type Hall switch devices and corresponding circuits. The MCU obtains the state of the three Hall switches through the input capture interrupt, so as to determine the current position of the rotor.
[0048] The control program adopts the control strategy of the prese...
