Embodiment Construction

[0046] The various embodiments of the present invention can be completely the same in the adjustment mechanism as the adjustment mechanism of the movable brush and the fixed brush adopted in the Chinese Invention 5 of the present inventor. All the embodiments of the present invention mainly state the working principle of the signal generator, without repeating the details of the adjustment mechanism.

[0047] The preferred embodiment of the present invention is a photoelectric SRM using a phototube as a sensor. Among them, there are three different preferred embodiments for different adjustment mechanisms.

[0048] This photoelectric reluctance motor is composed of a motor body and a photoelectric controller. The photoelectric controller is composed of a photoelectric signal generator and a power output unit; the power output unit is composed of a power switch tube group and its trigger control circuit, and the power output unit and The power output part of the traditional SRD is ...

Abstract

The invention provides a non computer-controlled switch magnetic resistance motor, which consists of a motor body and a signal controller, wherein the signal controller consists of a signal generator and a power outputting unit, and the power outputting unit is equal to a power outputting part of the traditional switch magnetic resistance motor. The signal generator consists of a switch board and a sensor board wherein the number of signal open regions on the switch board is equal to the number of poles of rotors, the angle equations of the signal open regions are equal to phase winding conduction angles, and the amount of the non-contact sensors on the sensor board is equal to the phase number of the motor. Three embodiments of the motor provides three processing schemes to the signal open regions and the position of the sensor board from simple to complex, thereby being capable of perfectly reappearing the conduction angle of the traditional switch magnetic resistance motor and the control mode when being communicated on the non computer-controlled switch magnetic resistance motor.

Description

Technical field [0001] The invention relates to a switched reluctance motor based on a non-contact position sensor, particularly a photoelectric switched reluctance motor, belonging to a switched reluctance motor that does not need to be controlled by a computer program. Background technique [0002] The traditional switched reluctance motor (SRM) is operated under the control of a computer program. This SRM is composed of a motor body and a switched reluctance motor controller (SRD). The motor body includes a motor and a rotor position sensor, and the SRD includes a computer controller and a power output device. Usually the rotor position sensor is a grating sensor. The higher the density of the grating, the higher the control accuracy, but the higher the requirement for computer operation speed. [0003] Although there are non-contact position or angle sensors like photoelectric switch elements in traditional SRM, these sensors are rotor position sensors of SRM. SRD requires a...
