一、引言东方红型内燃机车上的风泵电机,换向器隔片烧伤是该型电机运行中的惯性故障。这是由于该型电机的定额工况为连续,而实际为断续工况,电机处于频繁的冲击负载下工作,使换向极磁路产生涡流,换向极磁通滞后于电枢电流,因而引起换向恶化,发生换向器隔片烧伤。这种换向磁通的滞后,一般可采用如下改蒋措施: I. INTRODUCTION The wind pump motor and the commutator diaphragm burn on the Dongfang Red Locomotive are the inertial faults of this type of motor. This is because the rated working condition of this type of motor is continuous, but actually it is intermittent working condition, the motor works under frequent impact load, making the commutation pole magnetic circuit produce eddy current, the commutating pole flux lags behind the armature current, Thus causing the commutation to deteriorate, commutator septum burn occurred. The hysteresis of the commutation flux can generally be used to change the following measures Jiang:
