Description
Technical field
The compound rectifier excitation structure of the double salient-pole electric machine that the present invention relates to belongs to the excitation winding of double salient-pole electric machine and the pattern that is connected of armature winding.
Technical background
Professor Lipo of Wisconsin-Madison university waits has increased permanent magnet excitation on the basis of switched reluctance machines, proposed doubly salient permanent magnet motor.This motor belongs to a kind of variable reluctance motor, its stator, and rotor is salient-pole structure, is formed by silicon steel plate packing, and is simple in structure, do not have winding on the rotor, and reliability is high, in addition, also has the power density advantages of higher.
Electric excitation biconvex electrode electric machine (" brushless DC electric generator with dual salient poles ", Chinese invention patent: June 9 1999 applying date, Granted publication CN1099155C) replaces permanent magnet with electric excitation winding, makes the excitation field of motor to regulate.Do generator when work, do not need rotor-position sensor, and excitation winding only needs the single tube converter to supply power, regulate excitation winding electric current adjustable output voltage, but demagnetization during fault has high reliability features.When making motor, can realize wide speed adjusting performance.
For the exciting current that makes the electric excitation dual protrusion pole generator littler; Can adopt the scheme of composite excitation; Like block form double-convex pole hybrid excitation motor (double-convex pole hybrid excitation motor, Chinese invention patent: November 19 2003 applying date, Granted publication CN100361373C), radial magnet steel double salient-pole mixed excitation electric machine (radial magnet steel double salient-pole mixed excitation electric machine; Chinese invention patent: August 23 2006 applying date; Granted publication CN100424967C), radial magnet steel double salient-pole mixed excitation electric machine (radial magnet steel double salient-pole mixed excitation electric machine, Chinese invention patent: August 23 2006 applying date, Granted publication CN100438280C).
The present invention tries hard to seek a kind ofly add the littler new double salient-pole electric machine structure of controlled exciting current, and makes generator obtain harder external characteristic.
Summary of the invention
The object of the present invention is to provide a kind of new excitation topological structure of the little double salient-pole electric machine of exciting power that adds.
The series excitation structure of the double salient-pole electric machine that the present invention includes, its formation are that the part of double salient-pole electric machine or whole excitation winding are connected in the armature DC loop, make exciting current identical with the change direction of armature supply.When this topology was used for generator, the exciting power that need add was little, external characteristic is hard, and in some occasions that permanent magnet excitation is arranged even can add under the situation of excitation in cancellation, the variation of output voltage is very little when making load change.In addition, because the excitation winding of series connection is equivalent to filter inductance, the output capacitance that makes generator need reduces.When this topology was used for motor, along with the increase of armature supply, exciting current also increased, and made the mechanical characteristic hardening of motor.
The shunt excitation structure of the double salient-pole electric machine that the present invention includes; Its formation is that the part of double salient-pole electric machine or whole excitation winding are connected in parallel in the armature DC loop; When this topology is used for generator; Because the powered that the excitation winding of shunt excitation part is sent by armature winding, the exciting power that need add is little.When this topology was used for motor, the excitation winding of shunt excitation part was by the power supply of armature power supply, and this voltage remains unchanged usually.
The present invention can be applied to electric excitation biconvex electrode, mixed excitation biconvex pole motor T etc. to have on the double salient-pole electric machine of excitation winding.
