Title:
DOUBLE-ROTOR DYNAMOELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2018082600
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To restrain reduction in torque due to a coupling hole provided in the stator, in a double-rotor dynamoelectric machine.SOLUTION: A double-rotor dynamoelectric machine 10 includes as a stator 20, a stator core 22 having a center yoke 24, outer peripheral side teeth 26, and inner peripheral side teeth 28, an outer peripheral side coil 42 and an inner peripheral side coil 44. Furthermore, an outer rotor 50 and an inner rotor 60 are arranged, respectively, on the outer peripheral side and inner peripheral side of the stator 20. Fixing means 68 for fixing the stator 20 to an external attachment part by engaging with a fastening hole 70 is also provided. The outer peripheral side coil 42 and the inner peripheral side coil 44 are in-phase, and the insertion direction of the winding into an outer peripheral side slot 30 and the inner peripheral side slot 32 are same. The fastening hole 70 is provided on the outside of the width region in the center yoke 24, when the width of the outer peripheral side teeth 26, and the width of the inner peripheral side teeth 28 are extended.SELECTED DRAWING: Figure 1
