Abstract
A novel rotor damping structure for four-pole solid magnetic pole synchronous motors is structurally characterized in that damping rings are in the shape of a knife, one end of each damping ring 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 the 16 damping rings and the pole shoes form a damping winding through a specific connection mode. The starting performance of motors can be improved while the effective material utilization rate of motors is increased. The novel rotor damping structure of the invention is especially applicable to the field of large high-speed motors.
Description
Technical field
The present invention relates to a kind of novel four pole solid magnetic pole synchronous electric motor rotor damping structures, particularly can be used in the damping structure on four pole solid magnetic pole synchronous machines.
Background technology
According to electric machine theory, while the effective stock utilization as far as possible improving motor, improve the starting performance of motor, most effectual way increases damping structure on rotor.Because four pole solid magnetic pole synchronous machine rotating speeds are high, rotor structure is special, makes to increase damping ring difficulty larger.At present, the rotor structure of the existing four pole solid magnetic pole synchronous machine many employings undamped rings of domestic electric machine industry, starting performance is poor, and effective stock utilization is low.
Summary of the invention
For improving four pole solid magnetic pole synchronous motor starting performances, improve effective stock utilization of motor, the invention provides a kind of novel four pole solid magnetic pole synchronous electric motor rotor damping structures, this structure not only can be safe and reliable be used on high-revolving four pole solid magnetic pole synchronous machines, and the low operation of cost is simple, more importantly can improve motor starting performance, improve effective stock utilization of motor.
The technical solution adopted for the present invention to solve the technical problems is: the copper damping ring of design knife-edge, each pole installs 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, to damping ring end that rotor yoke overlaps mutually be fitted in and yoke portion holes jointly, be fixed on rotor yoke with high-strength bolt, when electric motor starting, induced current flows through pole shoe, damping ring, adjacent damping ring, next pole shoe, and circulating with this is finally closed into damping circuit.Tight problem is electrically connected, cushioning one deck silver pad between damping ring and electrical machinery pole shoe end for solving between damping ring; And carry out silver soldering at damping ring and pole shoe and yoke contact site, make damping ring safe and reliable in rotor high-speed rotation.
The invention has the beneficial effects as follows, propose four pole solid magnetic pole synchronous machines and increase a kind of solution of damping rings and technique simple possible, improve motor starting performance, make high-power four pole solid magnetic pole motor across-the-line startings when user load inertia is larger, improve effective stock utilization of motor.
