直流电机火花很大与什么原因有关?

有换向火花发生的原因是多种多样的,必须在很多的因素中,找到主要原因,方能排出毛病,改善换向。查看换向恶化原因的办法。一般称换向条件正常化查看和调整,是直流电机换向事端处理中常用的办法,其原理如下。
There are many reasons for the occurrence of reversing sparks. We must find out the main reasons among many factors in order to eliminate the faults and improve the reversing. Look at the causes of reversal deterioration. Normalization of commutation condition is a common method in DC motor commutation processing. Its principle is as follows.
一台直流电机在刚投入运转或过去运转中,换向一直是正常的,而在以后的运转过程中,逐步变坏或俄然恶化,说明电机在换向恶化前,其滑动接触、电机结构和电机各部件工作情况是正常的。
The commutation of a DC motor is always normal when it has just been put into operation or in the past, but it deteriorates gradually or abruptly in the subsequent operation, which indicates that the sliding contact, motor structure and the working conditions of the motor components are normal before the commutation deteriorates.
在电机运转过程中,某些部件的工作状况发生了改动,或周围环境发生变化,从而破坏了滑动接触,改动了正常的换向状况,而导致换向的恶化。假如对这些影响电机换向的因素进行全面查看和调整,使其能康复本来的正常状况,则换向即能康复正常。

In the process of motor operation, the working condition of some parts has changed, or the surrounding environment has changed, which destroys the sliding contact, changes the normal commutation condition, and leads to the deterioration of commutation. If these factors affecting motor commutation are comprehensively checked and adjusted to enable it to recover its normal condition, then commutation can recover its normal condition.
换向正常化查看是直流电机寻觅换向事端原因和排除毛病的常用办法,它包含如下主要项目:
Commutation normalization checking is a common method for DC motor to find out the cause of commutation and to eliminate its faults. It includes the following main items:
1.换向器片间电阻丈量
1. Measurement of the resistance between commutators
2.换向器摆度丈量
2. Measurement of commutator swing
3.电刷中性面的查看
3. Viewing the Neutral Surface of Brush
4.极距、刷剧和气隙的查看与调整
4. Viewing and Adjusting Pole Distance, Drawing Drama and Air Gap
5.电刷和刷握工作性能查看
5. Viewing the working performance of brushes and brush grips
