Title:
ELECTRIC VEHICLE, WHEEL AND SWITCHED RELUCTANCE MOTOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/015064
Kind Code:
A1
Abstract:
Provided are an electric vehicle, a wheel and a switched reluctance motor thereof, the switched reluctance motor (10) comprising a stator (11), a switch drive circuit (21) and an inductance sensor (38). Wherein the stator is axially provided in segmentes with at least three stator assemblies (111, 112, 113). Each of the stator assemblies comprises a plurality of stator teeth (131, 132, 133) periodically disposed in a circumferential direction of the stator and spaced apart from each other by stator slots (134, 135, 136) and windings wound around the stator teeth. The stator teeth of at least three stator assemblies are sequentially shifted by a predetermined angle in a circumferential direction of the stator. The windings in each stator assembly are in-phase windings, and the switch drive circuit is connected to the DC power supply and the windings of at least three stator components. An inductive sensor is coupled to the switch drive circuit for detecting an inductance value of the windings of each stator assembly. The switch drive circuit controls the DC power source to sequentially apply a drive current to the windings in a driving period corresponding to the at least three stator components according to the inductance value. The switched reluctance motor can avoid setting multiple position sensors and reduce costs.
