In prior art, the advantage of brush direct current motor is that structure is simple, control system is simple, cost is lower, its shortcoming mainly contain following some:
1), commutator and carbon brush need often to change, and subsequent maintenance cost is higher;
2), noise and spark can be produced in running, the larger noise of carbon brush abrasion degree and spark also larger, affect treadmill comfortableness and fail safe;
3), brush direct current motor torque performance is poor, it is little to exert oneself, and machine system power density is low;
4), allow permissible velocity low, be not suitable for high speed treadmill;
5), brush direct current motor system easy overcurrent damage controller and motor when running into greater impact load, sometimes also can hold tripping operation by activated user sky, have a strong impact on the reliability of product.
In addition, the advantage of AC induction motor is brushless electric machine, and maintenance and repair simple economy and structure are simple, and design convenient for production, its shortcoming is:
1), operational efficiency is low, and run and need to provide larger exciting current, produce unnecessary electric energy loss, the electric energy of loss is converted to heat, affects electric system life-span and ambient temperature.
2), detent torque is little, and starting current is very large.It is large that band carries torque ripple when starting, and easily causes shake.
3), machine volume is large, is unfavorable for the miniaturized and design of treadmill machine system.
4), easily produce electric leakage, affect client's personal safety, have a strong impact on treadmill system electrical security.
5), allow the speed of service low, harmonic wave is large, is not suitable for high speed treadmill.
The comprehensively pluses and minuses of these two kinds of motors above-mentioned, should develop with a kind of motor being more suitable for treadmill and running.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the utility model pin be for technical problem to be solved provide a kind of volume little, lightweight, exert oneself large, efficiency is high, harmonic wave is low, vibration resistance, noise are low, the life-span is long, the treadmill permagnetic synchronous motor of easy-maintaining and maintenance.
The technical solution of the utility model is a kind of treadmill permagnetic synchronous motor, comprise support, rotor, stator winding, stator core, and radiator fan, described rotor is wound around stator winding outward, the centre position overcoat of described stator winding has stator to turn core, described stator turns core peripheral hardware organic block, described rotor comprises rotor core, rotor fan, rotating shaft, bearing, permanent magnet and NULL, described rotor core is cylinder, described rotating shaft is through the center of iron core, upper bottom surface and the bottom surface circumferential position of described iron core are respectively equipped with equally distributed rotor fan, in the upper bottom surface position of iron core, groove is provided with between described rotor fan and rotating shaft, permanent magnet is provided with in described groove, described permanent magnet is connected with rotating shaft by NULL, described NULL contacts with cylindrical upper bottom surface and is placed in rotating shaft, described bearing is placed in rotating shaft, be positioned at the upper bottom surface side of described NULL, described radiator fan is placed on shaft end position, be positioned at the bottom surface side of iron core, described rotor is connected with described support by bearing, this kind of brushless shop motor, system maintenance cost is low, detent torque is large, starting current is little, impact to electrical network when can improve the load capacity of treadmill system and reduce heavy load, in addition, the operational efficiency height very of this motor, 85%-90% can be reached, reduce costs.
As optimization, described support side is provided with louvre, described radiator fan is relative with louvre, this design can effectively help motor operationally to dispel the heat timely, can effectively reduce operation noise, make noise keep stable, can not increase in time and increase, be conducive to the comfortableness improving treadmill motion.
The utility model compared with prior art, has the following advantages and positive effect: this machine adopts brushless electric machine, and noise is little, and the operational efficiency of motor up to 85% ~ 90%, can significantly reduce production cost.This kind of motor is simple, and volume is little, facilitates the Miniaturization Design of treadmill, provides more design space.Due to non-carbonate, efficiency is high, system heating low, reach about 4 times of common electric machine the useful life of motor.Greatly reduce the maintenance cost of treadmill.
