Description
Technical field
The present invention relates to a kind of DC brushless motor, refer in particular to a kind of EC double-winding dc. brushless motor.
Background technology
In various servomotor, the performance of DC motor is best, and its volume is little, efficiency is high, it is large to exert oneself, starting torque is large, dynamic property good, control is convenient.Therefore, in high accuracy, high performance servo-control system, be often drive executive component with direct current machine.Brushless DC motor is a kind of novel direct-current motor substituting brush and commutator with electronics reversing switch and position transducer.It is detected by controller, rotor-position and motor body three part forms, and is the married product of electronic technology and motor technology.It is high that it has efficiency, speed-regulating range width, starts rapidly, mechanical property and regulating characteristics good, the life-span is long, easy to maintenance, reliability is high, the features such as noise is low, non-commutation spark and radio interference.But the work of brushless DC motor depends on extraneous control, comprise and rotate forward driving, reversion driving and rotating speed control etc.
, when motor is used for hot environment (more than 30 DEG C), easily there is alternate winding punch-through, cause motor cisco unity malfunction in current EC motor.
Summary of the invention
The object of the invention is to the defect for above-mentioned prior art and deficiency, provide that a kind of winding is resistance to be punctured, the EC double-winding dc. brushless motor of long service life.
For achieving the above object, the present invention adopts following technical scheme:
A kind of EC double-winding dc. brushless motor; comprise bobbin, drive circuit; described drive circuit comprises power supply input, protective circuit, rectification circuit, voltage stabilizing circuit, amplifying circuit, winding and controls the circuits for triggering of technotron of rotating; described bobbin winding portion is provided with barrier wall; bobbin is divided into two parts, and two phase windings are respectively around two ends.After two phase windings separate, double winding EC motor can use in hot environment, and winding not easily punctures.
Further, described bobbin is that polyhexamethylene adipamide is one-body molded.It also can keep stronger strength and stiffness at higher temperature, and viscosity is lower, good fluidity.
Further, described bobbin is the polyhexamethylene adipamide of the glass containing 30%.Polyhexamethylene adipamide shrinkage is comparatively large, between 1% to 2%, after having added glass, can reduce shrinkage, make shrinkage be less than 1%.
Further, described bobbin is a rectangular-shaped skeleton on the whole, and the end at skeleton two ends is provided with barricade and metal wound wire termination.The barricade of the end at skeleton two ends is used for blocking winding, prevents winding to be scattered.
Further, winding protection circuit is provided with between described two windings.By arranging protective circuit between winding, the instantaneous pressure produced during two-phase break-make being discharged, avoiding puncturing damage field effect transistor, avoiding electrical fault.
Further, described winding protection circuit comprises a voltage stabilizing didoe and two backward diodes.Electric current is by discharging the high pressure produced instantaneously through voltage stabilizing didoe after two backward diodes, and holding circuit voltage stabilization, avoids high-voltage breakdown field effect transistor.
Further, two voltage stabilizing didoes are comprised in the circuits for triggering of the technotron of described control rotating.
The invention has the beneficial effects as follows: after (1) two phase winding separates, double winding EC motor can use in hot environment, and winding not easily punctures; (2) being improved by drive circuit, eliminating two phase windings separately only high pressure around producing.
Accompanying drawing explanation
Fig. 1 is bobbin schematic diagram of the present invention;
Fig. 2 is driving circuit principle figure of the present invention;
Fig. 3 is the driving circuit principle figure of prior art.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated.
It is bobbin schematic diagram of the present invention in Fig. 1.By the barrier in the middle of bobbin, make two phase windings separately.Described bobbin is one-body molded with the polyhexamethylene adipamide containing 30% glass, and it also can keep stronger strength and stiffness at higher temperature, and viscosity is lower, good fluidity.
As shown in Figure 2, described drive circuit comprises power supply input, protective circuit, rectification circuit, voltage stabilizing circuit, amplifying circuit, winding and controls the circuits for triggering of technotron of rotating, is provided with winding protection circuit between described two windings.After power supply input circuit; by protective circuit and rectification circuit and voltage stabilizing circuit; after transistor amplifier; by controlling the rotating of the circuits for triggering controlled winding of the technotron of rotating; between two windings, increase winding protection circuit, described winding protection circuit comprises a voltage stabilizing didoe and two backward diodes.Electric current is by discharging the high pressure produced instantaneously through voltage stabilizing didoe after two backward diodes, and holding circuit voltage stabilization, avoids high-voltage breakdown field effect transistor.And a voltage stabilizing didoe is increased in the circuits for triggering of the technotron of original control rotating.
Above-described embodiment only lists the present invention's preferably execution mode, is not used for limiting protection scope of the present invention, as long as the equivalence change done in protection scope of the present invention and modification, all should fall into protection scope of the present invention.
