Title:
ROTARY MOTOR
Document Type and Number:
Japanese Patent JP2014225978
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary motor whose weight is reduced while torque lowering is suppressed.SOLUTION: In a motor 1, a weight is reduced by forming notch parts 9c, 10c at outer peripheral surfaces of a first stator iron core 9 and a second stator iron core 10. Since the notch parts 9c, 10c do not interfere with a flow of a flux generated by a permanent magnet 12 and reduce a leaked magnetic flux at surfaces of the first stator iron core 9 and the second stator iron core 10, torque reduction may be suppressed.
