Before have become one of the research hotspot in International Power field, in aviation, ship, hybrid vehicle, high speed grinding machine, accumulated energy flywheel
And there is vast potential for future development in distributed generation system.
High-speed high frequency motor design difficulty compared with common electric machine is larger, and high-speed electric expreess locomotive rotating speed is up to tens thousand of turns per minute very
To ten tens of thousands of turns, for peripheral speed up to 200m/s or more, under the circumference of the high-speed rotation, stator core loss is very big for motor, empty
The friction of gas and rotor surface can bring prodigious loss, for high-speed permanent magnet motor, rotor permanent magnet to motor
Eddy-current loss it is very big, however the heat dissipation of the rotor of motor is difficult, the temperature of rotor can be caused to rise excessively high, and permanent magnet is in temperature
Irreversible demagnetization can occur in the case of spending height, cause to seriously endanger to motor, therefore the loss for reducing rotor becomes
One of the key problem of high-speed permanent magnet motor design.For high-speed permanent magnet motor, rotor strength problem is more prominent, because
Permanent magnet cannot bear the tensile stress of high speed rotation generation and must take safeguard measure to permanent magnet.
Compared with internal rotor high-speed electric expreess locomotive, the diameter of external rotor electric machine is big, the centrifugal force bigger to be born of high speed rotation, together
When rotor directly with other structures coordinate, need to bear certain pressure loading, therefore put forward higher requirements rotor strength.
