Specific embodiments
This routine refrigeration compressor adopts the magneto magnetic resistance switch speed-adjustable motor as drive unit.Concrete structure is as follows:
Casing 14 is cylindrical pressure vessels made from the A3 steel plate, and compressor pump 2 is equipped with in cylindrical casing inner chamber bottom, and compressor pump is in transmission connection with the main shaft 7 that is contained in the motor on its top, and is connected with the gas-liquid separator 12 of outside.
Motor 1 is a three-phase permanent formula magnetic resistance switch speed-adjustable motor, referring to Fig. 2, its stator 3 usefulness ordinary silicon steel discs are overrided to form, be provided with 6 interior salient poles, the driving winding 5 of enameled cable coiled all is housed on the salient pole, and connection is that A-A ', B-B ', C-C ' symmetry connects, serial or parallel connection, and the high energy product permanent magnet of two linear demagnetization curves made from rare-earth Nd-Fe-B permanent magnetic material is housed in the stator, two permanent magnets 4 are separated by on stator, and 180 degree are symmetrical to be installed
The purpose that permanent magnet 4 is installed is: from the viewpoint of transformation of energy, conventional switched reluctance motor only can obtain the utilization ratio of half, because the direction of electromagnetic torque is by the variance ratio decision of winding inductance with corner, irrelevant with electric current, so when the inductance rising stage passes to electric current, produce the positive direction actuation torque; When passing to electric current, the inductance decrement phase produces retarding torque, like this in a switch periods of staor winding, have only half period to obtain utilizing at most, for avoiding producing retarding torque in inductance decline district, the pass angle of rupture of winding current is had to morely in advance in the maximum induction position, half period all is underutilized, produced the low problem of change of current problem and relative material utilization ratio thus, this example is set up a magnetic field with pre-the giving birth to of permanent-magnet material in motor stator, by control staor winding current direction, make the magnetic field of permanent magnet generation and the magnetic field interaction that winding current produces, just can be implemented in inductance decline district and also can produce forward torque, thereby improve the performance of magneto switched reluctance motor greatly
