The invention discloses a sectional type switch
reluctance motor, belonging to the field of
magnetic circuit components. The sectional type switch
reluctance motor comprises a main shaft, at least two sections of stators, at least two sections of rotors and magnetic isolating plates arranged on the main shaft, wherein each section of the stators and each section of the rotors are respectively provided with magnetic isolating plates, and each section of the stators and each section of the rotors are uniformly distributed around 360 degrees in the axial direction respectively.
Stator poles of each phase of each section of the stators are respectively connected in series and are connected with a one-way guide circuit; the one-way guide circuit comprises four
rectifier diodes,
energy storage capacitors, main control
thyristor switches and guide
thyristor switches which are connected in series two by two; series circuits of each
stator pole are mutually connected in parallel; one ends of the series circuits are respectively connected with the main control
thyristor switches and guide thyristor switches; and the middles of two series circuits of the
rectifier diodes are respectively connected with two output ends of the alternative current. By utilizing the sectional type switch
reluctance motor, output torque pulse can be effectively reduced, and by guiding the induced current among the sections, the
energy consumption efficiency of a
system is improved, the
impact of the induced current to the components is reduced, and the service life of the
system is prolonged.
