SRMImproved Radial Force Reduction Switched Reluctance Motor

摘要

The present invention relates to an improved radial force reduction SRM, and more particularly, to an "improved radial force reduction SRM" for reducing vibration and noise by improving the shape of a rotating magnetic pole to reduce radial force. it's about The improved radial force reduction SRM according to an embodiment of the present invention includes a stator surrounded by a winding having a plurality of stator poles, and a rotor accommodated inside the stator and having a plurality of rotating poles facing outward. The rotational magnetic pole has a hollow hole portion formed therein in the longitudinal direction, and the hole portion corresponds to 40 to 60% of the length in the longitudinal direction and is equally divided in the longitudinal direction. The second hole is formed to reduce the radial force. In addition, the first and second hole portions are arranged to be spaced apart from each other by a predetermined distance in the longitudinal direction, and the hole portions are spaced apart from each other by the predetermined distance at both ends in the longitudinal direction. In addition, the diameter of the hole portion is less than 1/2 of the rotor width. In addition, the stator has six stator poles, and the rotor has four rotating poles. Alternatively, the stator has 12 stator poles, and the rotor has 8 rotation poles.
