The invention discloses a special motor in the wind power field, comprising a winding stator, a chute provided with the winding stator and insulated into two layers and a notch provided with the winding stator and insulated into three layers, wherein as for the bilayer chute, the outer layer is insulating paper which is made of a tri-layer composite material formed by adhering a pure longitudinal polyester non-woven cloth and a polyester film by resins and has the thickness of 0.21mm; and the inner layer is an electrically insulated thin film with the thickness of 0.15mm. As for the tri-layer notch, the outermost layer is insulating layer which is made of a tri-layer composite material formed by adhering a pure longitudinal polyester non-woven cloth and a polyester film by resins and has the thickness of 0.21mm; the interlayer is part of the insulated outer layer of the chute exposed out of the notch, is made of a tri-layer composite material formed by adhering a pure longitudinal polyester non-woven cloth and a polyester film by resins and has the thickness of 0.21mm; and the inner layer is an electrically insulated thin film with the thickness of 0.15mm, which is a part of the insulated inner layer of the chute exposed out of the notch. The special motor in the wind power field has greatly improved insulating strength, and completely satisfies the requirements of high reliability and long service life and the requirements of a special supply power on motors.
Description
technical field [0001] The invention relates to a high-insulation-strength, high-performance motor specially designed for the wind power field and designed for the characteristics of the wind power field. Background technique [0002] The existing winding stator slot insulation and slot insulation of the motor in the wind power field adopts double layers. The first layer is composed of pure longitudinal polyester non-woven fabric and polyester film, and is bonded with F-grade resin. Three-layer composite material F grade 0.21mm thick insulating paper; the second layer is made of: F grade 0.15mm thick electrical insulation film. The problem with adopting such a structure is that since the motor power supply in the wind power field is powered by an inverter (not an ideal sine wave power source generated by a generator), there are often phenomena such as motor winding insulation breakdown, inter-turn short circuit, and bearing necrosis.
