                               due to some improper rotor design of 1la4312-2an30-z 250kw 3kv siemens motors made in germany, problems usually occur to this type of motors. the magnetic flux density of the tooth is too high, and the temperature rise of the tooth part and the rotor core is too high. the rotor and the stator rub because of the rotor thermal expansion. our company used the original motor case, redesigned and reproduced the rotor and the stator, then improved the motor performance. in the test by the power plant, temperature rise in operation reduced by 20k, and the current reduced by 5a.
