Title:
DYNAMO-ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/064376
Kind Code:
A1
Abstract:
Provided is a dynamo-electric machine in which vibration occurring during driving can be suppressed and which can be made compact. This dynamo-electric machine is provided with: a rotor 1; a stator 2 having a stator core 21 provided outside the rotor in the radial direction of the rotor 1; a motor frame 3 which has a cylinder section 31 provided outside the stator core 21 in the radial direction and to which the stator 2 is affixed; and an intermediate member 4 provided to the outer peripheral surface, in the radial direction, of the stator core 21 while being press fitted in the inner peripheral surface, in the radial direction, of the cylinder section 31. The rigidity per unit length of the intermediate member 4 is higher than the rigidity per unit length of the cylinder section 31.
