Abstract
The utility model relates to a rotor damping structure of a four-pole solid magnetic pole synchronous motor. The structure is characterized in that a damping ring is in the shape of a knife, one end is connected with the end part of a rotor pole shoe through a bolt, the other end is connected with a magnetic yoke through a bolt, and 16 damping rings and the pole shoes form a damping winding through a specific connection mode, thereby being capable of improving the starting performance of the motor while improving the effective material utilization rate of the motor, and being particularly suitable for the field of large motors with a high rotating speed.
Description
Technical field
The utility model relates to a kind of novel four utmost point solid magnetic pole synchronous electric motor rotor damping structures, particularly can be used in the damping structure on four utmost point solid magnetic pole synchronous machines.
Background technology
According to electric machine theory, when improving effective stock utilization of motor, improve the starting performance of motor as far as possible, most effectual way is on rotor, to increase damping structure.Because four utmost point solid magnetic pole synchronous machine rotating speeds are high, rotor structure is special, makes to increase damping ring difficulty larger.At present, existing four utmost point solid magnetic pole synchronous machines of domestic electric machine industry adopt the rotor structure of undamped ring more, and starting performance is poor, and effectively stock utilization is low.
Summary of the invention
For improving four utmost point solid magnetic pole synchronous motor starting performances, improve effective stock utilization of motor, the utility model provides a kind of novel four utmost point solid magnetic pole synchronous electric motor rotor damping structures, this structure not only can be safe and reliable be used on high-revolving four utmost point solid magnetic pole synchronous machines, and the low operation of cost is simple, main is to improve motor starting performance, improves effective stock utilization of motor.
The utility model solves the technical scheme that its technical problem adopts: the copper damping ring of design knife-edge, each utmost point is installed 2, each damping ring one end and pole shoe end face are fixed by high-strength bolt, the other end is fitted in rotor yoke, treat that all damping rings install, by being fitted in damping ring end and the yoke portion that rotor yoke overlaps mutually, jointly hole, be fixed on rotor yoke with high-strength bolt, when electric motor starting, induced current flow through pole shoe, damping ring, adjacent damping ring, next pole shoe, circulate and be finally closed into damping circuit with this.For solving between damping ring, be electrically connected tight problem, cushioning one deck silver pad between damping ring and electrical machinery pole shoe end; And carry out silver soldering at damping ring and pole shoe and yoke contact site, make damping ring safe and reliable in rotor High Rotation Speed process.
The beneficial effects of the utility model are, a kind of solution and the technique simple possible of four utmost point solid magnetic pole synchronous machines increase damping rings have been proposed, improved motor starting performance, make high-power four utmost point solid magnetic pole motor across-the-line startings in the situation that user load inertia is larger, improve effective stock utilization of motor.
