Background technology
At present, directly drive the turntable that permanent magnet torque motor mainly is confined to machining center, following machining center is wished to collect car, is milled, mill, laser processing etc. are one.By the workbench that permanent magnet torque motor directly drives, not only be used for calibration and location, and can be used as main shaft and carry out turning processing.Require the Large-power High-Speed running when Vehicle Processing, speed of gyration requires the thousands of commentaries on classics of per minute; Mill to add and require the powerful milling of large torque low speed, high acceleration man-hour again, torque reaches thousands of ox rice, and speed of gyration per minute tens changes, even lower.
The excitation field of permanent magnet synchronous motor is provided by permanent magnet, under the certain condition of inverter power, want to realize high torque density, must guarantee higher air-gap field intensity, if but it is just impossible to adopt weak magnetic mode to improve rotating speed of motor on a large scale, because be subjected to the restriction of inverter power.Therefore the conventional structure permanent magnet torque motor is difficult to realize simultaneously wide speed regulating range and big torque.
Summary of the invention
The invention provides the compound main shaft permanent magnet synchronous torque of the turnning and milling motor of a kind of big torque, wide speed regulating range, change air-gap field by the magnetic conductance that changes epitrochanterian magnetic conduction bridge, thereby realize big torque and wide speed regulating range.
For achieving the above object, the present invention is by the following technical solutions:
The compound main shaft permanent magnet synchronous torque of the controlled turnning and milling of a kind of magnetic conductance motor comprises stator core installed inside rotor core, mounts permanent magnet between rotor core and stator core; The stator slot that is arranged on the rotor core is placed three phase windings, it is characterized in that: embed in the rotor core after the controlled coil of magnetic conductance is installed on the magnetic conduction bridge, perhaps directly generate the magnetic conduction bridge in the punching of rotor core, twine the controlled coil of magnetic conductance then on the magnetic conduction bridge.
Stator core 1 is overrided to form by silicon steel sheet.
Rotor core 3 is overrided to form by silicon steel sheet.
The magnetic conduction bridge is bar shaped.
Rotor core employing face dress formula or plug in construction.
Control the rotor core magnetic conductance by the controlled coil current of control magnetic conductance, and then the control air-gap field, realize wide-range-timing.
Concrete advantage of the present invention is as follows:
1) it is very little to offer the power of the controlled coil of magnetic conductance, the magnetic conductance of magnetic conduction bridge on the change rotor that very little power just can be bigger, and then change air-gap field, and control is simple, and speed adjustable range is very wide.
2) sense of current of the controlled coil of change magnetic conductance can increase magnetic and degaussing, and then changes air-gap field, adjusts torque and rotating speed.
