Description
Technical field
The utility model is related to magneto fields, are specially a kind of hybrid novel permanent magnetic synchronous motor rotor structure.
Background technology
Traditional permanent-magnetic synchronous motor rotor structure is different according to the position of permanent magnet, is broadly divided into face paste formula and built-in
Formula.Face paste formula magneto action response is fast, but power density is low, and interior permanent magnet machines torque is big, and overload capacity is strong, but leaks
Magnetic protrudes.In addition, the approximate rectangular ripple of traditional Air-gap Flux Density in Permanent Magnet Machines so that empty load of motor counter potential waveform distorts,
The fluctuation of motor cogging torque is larger；Therefore, it is necessary to be further improved in the structure of rotor, using face paste formula and built-in
Formula permanent magnet mixed magnetic circuit to improve the superiority of motor, makes it that can be widely used in mining, metallurgy and high-precision control etc.
Field.
Utility model content
The utility model aim is to provide a kind of hybrid novel permanent magnetic synchronous motor rotor structure, to solve traditional permanent magnetism
The technical problems such as motor flux density is uneven, and leakage field protrudes, and cogging torque is big, make motor performance more excellent.
