摘要： A controller for a reluctance type synchronous motor. When field current control depends solely on a rotor speed, large power consumption and heat generation of a motor may be caused. Also, when a field current is small, torque consumption becomes small, resulting in a prolonged acceleration time. To address the above problems, there is provided a section for generating a field current command SIFC using a field current compensation coefficient SKF having been obtained based on a torque command STC. With this arrangement, a large field current SIFC flows when a torque is needed, and a small field current SIFC flows when torque is not needed. There is also provided a section for generating an armature current command SIAC using armature current command compensation SKA having been obtained based on a field current command SIFC. With this arrangement, variation of a torque constant due to variation of a field current is converted into an armature current command SIAC based on a field current command SIFC.

摘要： In an armature current limit value calculator section, limitation is applied to a pre-limitation torque command ST in correspondence with a presently detected speed SPD, to calculate a torque command STC. Meanwhile, in a field current calculator section 12, a pre-correction field current command value SF is decreased in correspondence with the detected speed SPD when the speed is large. In addition, a coefficient K.tau. which increases when the torque command is large is calculated on the basis of the pre-limitation torque command ST at this time. Further, a field current command is calculated from an equation SFC=K.tau.*SF. A current command calculator section 3 prepares a current command on the basis of the torque command STC and the field current command SFC supplied, and drives an electric motor 5 via a current control section 4.

摘要： A reluctance type synchronous motor comprises: a stator with a plurality of slots placed at an even pitch angle wherein stored inside each slot is a stator winding for creating stator magnetic poles with a predetermined phase alternating current being supplied thereto. A rotor sustained by a shaft and changing magnetic reluctance in its circumferential direction by inclusion inside of a plurality of magnetic isolating portions creates desired magnetic poles. At least one of the central angles between magnetic poles created at the rotor is shifted from the other central angles so that torque ripples during rotation can be reduced.

摘要： A synchronous motor 100 includes a rotor 20 having a permanent magnet 26 on the surface of or inside the rotor, a stator 10 made of a soft magnetic material and having tooth members T1 to T18 and slots S1 to S18, and element coils 11, 12 wound around each of the tooth members T1 to T18 as concentrated windings and arranged in multiple layers along the extending direction of the tooth members T1 to T18. The element coils 11, 12 are provided three coils each for each phase in a circumferential direction to form rotating direction windings 101 to 206 for each phase. For each phase, the rotating direction windings 101 to 206 are displaced from each other by one slot in the rotating direction between adjacent layers. As a result, torque ripples are reduced in motors using concentrated windings.
