Abstract

The invention relates to a novel damping ring structure for a synchronous six-stage solid stator. The novel damping ring structure for the synchronous six-stage solid stator is structurally characterized in that a damping ring is in simple connection with the end portion of a pole shoe; the damping ring is simple in structure; obvious and reliable radial displacement limiting effects of the damping ring are obtained. Therefore, the damping ring can avoid being thrown away during the high-speed operating process of a motor rotor and accordingly is particularly applicable to the field of large high-speed motors.

Description

technical field [0001] This patent relates to a novel damping ring structure of a synchronous six-stage solid rotor, especially a damping ring structure in which the ends of the pole shoes are connected to the damping ring, and the damping rings between adjacent magnetic poles are connected to each other. Background technique [0002] For the existing synchronous six-stage solid rotor motors in the domestic motor industry, if it is necessary to increase the pull-in torque of the motor while improving the effective material utilization rate of the motor as much as possible, it is necessary to add a damping ring to the solid rotor of the motor. The conventional damping ring structure is difficult to connect tightly with the end of the pole shoe of the motor, and it is easy to discharge with the end of the pole shoe under the action of the rotor voltage when the motor is started, and the conventional damping ring structure is easy to be thrown out during the high-speed rotati...
