The invention relates to a
traction motor for a
hybrid power motor
train unit, in particular to a permanent
magnet generator for a
hybrid power motor
train unit. The permanent
magnet generator for the
hybrid power motor
train unit comprises a
machine base and an end cover, wherein a
stator assembly and a rotor
assembly are arranged in the
machine base, the
stator assembly is provided with a
stator coil, the rotor assembly is provided with a rotary shaft, a rotor iron core, a permanent
magnet baffle, a permanent magnet baffle pressing ring and a permanent magnet, a front inner sealing ring and a rear inner sealing ring are arranged at the two ends of the rotary shaft respectively, a punched piece of the rotor iron core is a permanent magnet structure which is provided with a thick magnetic steel tank and is of a V-shaped radial
magnetic structure, the
machine base is a cast-aluminum machine base and is of a structure formed by
casting two rows of spiral
copper pipes in parallel, the permanent magnet baffle pressing ring is of a cast-aluminum structure, and magnetic steel assembling and disassembling holes are evenly formed in the pressing ring. According to the motor, under the same size condition, the sectional area of the permanent magnet is increased, the
power density and demagnetization resistance of the motor are improved, fluctuation of output
voltage is reduced, the weight of the motor can be effectively reduced, and the margin of temperature rise of the motor is increased; meanwhile, the
self weight can be reduced through the cast-aluminum pressing ring, assembly of the motor can be guaranteed, design cost is reduced, operation reliability is improved, and the service life is prolonged.
