Description
Technical field
The present invention relates to a kind of motor, particularly a kind of tractor that is widely used in the automation fields such as water, air valve class uses with the synchronous machine of inhaling the iron function.
Background technology
the tractor that washing machine uses, should have straight line traction washing machine member, keep driving component, the function of action is so stage by stage replied in traction, tractor in the market and synchronous machine probably have two kinds, a kind of by one group of reduction gear component of synchronous machine drives, after making the driving component in-position, make the motor outage by the contactor form, stop operating, electromagnet keeps the energising adhesive, keep traction, the washing machine job step finishes, be that tractor all cuts off the power supply, effect by self restoring force of washing machine member is replied tractor, it is characterized in that electromagnet of tractor indoor design combines with switching circuit, brake one and be arranged on the carrier gear that plays the control startup in reduction gear component and reply.when beginning traction synchronous machine and electromagnet simultaneously electric, carrier gear is controlled in the electromagnet adhesive, reduction gear component is by motor-driven, behind the traction in-position, by switching circuit, with the motor deenergization, inhale iron and continue energising maintenance adhesive, whole gear assembly stops operating, because electromagnet braking carrier gear can't reverse, driving component is in keeps traction state, after the washing machine job step is completed, washing machine cuts off the power supply tractor, electromagnet is dead electricity simultaneously, electromagnet is by self extension spring reply, no longer brake carrier gear, replied by the member driven gear assembly reversing that is pulled of washing machine this moment, get back to initial state.This tractor is due to the electromagnet assembly of setting up, and the switching circuit part makes cost higher, has also increased difficulty for quality management.
another kind of tractor and synchronous motor structure, that control carrier gear principle with electromagnet drives one group of gear when changing into by one group of reduction gearing of synchronous machine drives again, the magnet steel that driving is provided with rotates, rotate the principle of copper ring or aluminium ring by cutting magnetic field, on copper ring or aluminium ring, gear is set, gear is the startup effect and overturning processed of the similar hook-shaped control carrier gear of one of radial drive again, after it is characterized in that tractor washing machine member in-position, lower separation device on one is set in gear assembly, by behind last gear or draw bar in-position the time, stirring this separator makes reduction gear component stop traction, the motor rotation of always working, another group gear makes magnet steel cut magnetic field with copper ring or aluminium ring cutting always, all the time control carrier gear, after the washing machine job step is completed, the tractor outage, stop operating after the synchronous machine dead electricity, one group of gear assembly of controlling carrier gear of its driving is replied under the effect of extension spring voluntarily, driving component drives the reversing of traction reduction gearing and replys.The shortcoming of this kind tractor is complex structure, replace electromagnet magnet ring, copper band, extension spring partly that the proportion relation of a power very rambunctious is arranged, and quality is extremely unstable, because manufacture difficulty is high, increased the cost of human cost and equipment aspect, so be equally also the cost that has increased product.
