Embodiment Construction

[0016] The switched reluctance generator of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 , 3 , 4, and 5: the switched reluctance generator of the present invention includes a stator 1 with twenty inward stator poles and a rotor 2 with twenty-four outwardly extending rotor poles. There are four large slots 7 on the stator 1, and each large slot 7 is actually formed by removing a stator tooth. The coil sides of the four coils 3, 4, 5, 6 are placed in the large slot 7, and each coil spans five stator teeth. Except for the position of the large slot 7, the tooth pitch of the stator teeth and the rotor teeth are the same, both are 360 / 24 degrees. The stator 1 and the rotor 2 are composed of ferromagnetic materials with good magnetic permeability, which are called stator core and rotor core respectively.

[0018] The electromagnetic torque on the rotor 2 of the switched reluctance generator is de...

Abstract

The invention relates to a switched reluctance generator (SRG), in particular relating to a generator capable of reducing copper dosage and copper loss structure for a motor winding. The SRG comprises winding consisting of a plurality of coils, a stator with a winding, a rotor with no winding, gears and grooves arranged on the stator and the rotor, and the stator is divided into big grooves and small grooves. Coil edges are arranged in the big groove and each coil spans over a plurality of stator gears. The switched reluctance generator is characterized in that four big grooves (7) are provided. Two or a multiple of two small grooves (8) are arranged between the big grooves (7). A first coil (3), a second coil (4), a third coil (5) and a fourth coil (6) are respectively arranged inside each big groove (7). Compared with the prior art, the invention has simple structure, reduces copper dosage, lowers system loss and improves efficiency on the condition that the generator has unchanged efficiency. The invention is suitable for a wind driven generator, and especially has a better effect in low speed operation.

Description

technical field [0001] The invention relates to a switched reluctance generator, in particular to a generator with a structure for reducing copper consumption and copper loss of motor windings. Background technique [0002] A switched reluctance generator (SR generator) is a device that converts mechanical energy into electrical energy. The device controls the connection mode of the winding and the energy storage device through an electronic switch, thereby controlling the flow direction of electrical energy between the motor and the energy storage device. , when operating as a generator, the device is first connected to the energy storage device, through which the winding has current flowing, and then changes the path of the current, and the device recovers more energy from the subsequent phase winding than the previous applied energy. The advantage of this SR generator is that its output is in the form of a current source, so it can charge the energy storage device at low ...
