200KW rare-earth permanent magnet generator

Abstract

The invention discloses a 200KW rare-earth permanent magnet generator, which comprises a stator, a rotor core, a magnetic shoe, a front end cover and a rear end cover, wherein rare-earth neodymium iron boron is adopted by the magnetic shoe as a magnetic source body; the stator comprises a plurality of stator punching plates; a round hoe matched with the rotor core is formed in the middle part of each stator punching plate; cramp grooves are formed in the edge part of each stator punching plate; 36 coil slots are evenly distributed in each stator punching plate on an outer ring of each round hole; the coil slots are T-shaped; the notch widths of the coil slots are 6mm; a T-shaped coil tooth is formed between the adjacent coil slots; and the minimum vertical distance between the adjacent coil slots is 9mm. The generator optimizes armature reflection and reduces the motor demagnetization effect; the generator has relatively small size, relatively light weight and relatively high stability, simultaneously has ultra-strong continuous overload capacity (greater than 20%); the rated power of the unit is 200KW; the maximum load power is 230KW; the time of duration is 4 hours; and the 200KW rare-earth permanent magnet generator does not need to maintain basically and can be used in a severe environment for a long period of time.

Description

technical field [0001] The invention relates to a generator, in particular to a 200KW rare earth permanent magnet generator. Background technique [0002] The stator of the generator is composed of three parts: the stator core, the stator winding and the frame. The stator core is composed of overlapping punched sheets of high magnetic permeability material. The structure of the punching plate directly affects the efficiency, life, performance and assembly production efficiency of the generator. [0003] However, the 200KW high-power rare-earth permanent magnet generator in the prior art often has high armature reflection due to the stator structure problem, which reduces the power generation efficiency of the motor. Contents of the invention [0004] The purpose of the present invention is to provide a 200KW rare earth permanent magnet generator capable of optimizing the armature reflection of the generator and reducing the demagnetization effect of the generator.
