Abstract
The utility model relates to a speed-adjustable oscillating motor, which has the technical proposal that end rings and guide strips on the rotors of the normal oscillating motor are made of lead brass. Since the resistivity of the lead brass is high, the rotors can not become too hot to damage the motor when the voltage is changed, and thereby, oscillation amplitude and exciting forces of the oscillating motor can be changed without shutting down the machine. The adjustment range of the device can reach 1: 10, and the rated power of the motor can be reduced as well. The utility model can normally save power by 17-40%.
Description
Speed governing vibrating motor of the present invention relates to a kind of stepless speed regulation exciting source of vibrating mechanical equipment.
A kind of vibrating motor was arranged in the past, and the size adjustment of its amplitude, exciting force is reaching by the angle of adjusting between the movable and fixed eccentric block in axle two ends after the shutdown.As not shutting down the change motor speed, one comes vibrating motor change stator voltage rotation speed change little, and fluctuation of service; Two reductions along with the vibrating motor rotating speed cause the corresponding increase of rotor power supply, cause it overheated and damage vibrating motor.
The present invention is intended to provide a kind of new vibrating motor, and it can infinitely variable speeds under non-stop-machine situation, can be in stable operation under the low speed, and unlikely again rotor is overheated, damages vibrating motor.
Task of the present invention is achieved in that to be made epitrochanterian end ring of vibrating motor and sliver with ledrite, like this, because the resistivity of ledrite is very high, be added in the different voltages on the stator winding after, rotor just can be in stable operation under the different rotating speeds and the unlikely cause thermal damage motor of crossing.Thereby reach automatic stepless and adjust required exciting force and amplitude.Speed adjustable range can reach 1:10, and this has just reduced the rated power of vibrating motor, than general vibrating motor economize on electricity 17-40%.
Accompanying drawing 1 is speed governing vibrating motor structural representation.
Further specify one embodiment of the present of invention in conjunction with the accompanying drawings.
End ring 3 and sliver 4 on the rotor 1 are all made with ledrite.After speed governing vibrating motor energized, press specification signal by speed setting controller and regulate rotating speed, promptly be that the voltage on the stator 2 changes, can not cause rotor overheated yet, thereby reach needed exciting force and amplitude.
Claims (1)
1, a kind of speed governing vibrating motor, it comprises casing, rotor 1, stator 2, it is characterized in that: the end ring 3 on the rotor 1 is made with sliver 4 usefulness ledrites.
