REINFORCED PERMANENT MAGNET SYNCHRONOUS MOTOR ROTOR FOR STARTING ON LINE

摘要

Disclosed in the present invention is a reinforced permanent magnet synchronous motor rotor for line-start, comprising: standard laminations, conductive bars, magnetic bars, and reinforced laminations; said reinforced laminations being located between standard laminations; the magnetic bars are embedded in the standard laminations and separated by the reinforced laminations, and said conductive bars run through the standard laminations and reinforced laminations overlying one other. Comparing the structures of the reinforced permanent magnet synchronous motor rotor for line-start provided by the present invention and the permanent magnet motor rotor in the prior art, the mechanical strength of the motor rotor is increased effectively and the service life of the motor rotor is lengthened by adding reinforced laminations, under the precondition that motor efficiency is not sacrificed.
