Abstract

The invention discloses an efficient-heat radiation and low-pulsation switched reluctance motor, which comprises a frame housing, a stator, a rotor, a front end cover and a rear end cover, wherein the rear part of the rear end cover is provided with a fan; a fan housing is arranged outside the fan; the stator comprises a stator iron core and a plurality of stator windings, an aluminum profile insulation sheet is embedded between adjacent two stator windings, and two ends of each aluminum profile insulation sheet are respectively connected onto the frame housing; a coolant flow hole from one end to the other end is arranged in each aluminum profile insulation sheet, the coolant flow holes in all aluminum profile insulation sheets are communicated via flow guide pipelines arranged at two ends, and the flow guide pipelines are also communicated with a heat radiation device outside the frame housing. The aluminum profile insulation sheet plays a role of reinforcing the winding coil, the stator coil and the stator can be combined more tightly, the heat radiation effects are better, the pulsation and the noise of the motor are reduced, and as the flow guide pipelines are also communicated with the heat radiation device outside the frame housing, heat inside the motor can be timely taken out.

Description

technical field [0001] The invention relates to a switched reluctance motor, in particular to a high-efficiency heat dissipation and low-pulse switched reluctance motor. Background technique [0002] Switched Reluctance Drive (SRD) is the latest generation of stepless speed regulation system developed after frequency conversion speed regulation system and brushless DC motor speed regulation system. It is a combination of modern microelectronics technology, digital technology, power electronics technology, infrared Optoelectronic technology and modern electromagnetic theory, design and production technology are integrated high-tech of light, machine and electricity. It has the advantages of both DC and AC speed control systems in the speed control system. Economically developed countries such as Britain and the United States started research on the speed control system of switched reluctance motors earlier, and have achieved remarkable results. The product power levels range...
