怎么判断直流微型减速电机的质量?

来源:http://www.jnmcd.com 发布时间:2018-12-19 浏览:
直流微型减速电机质量好坏的判断方法如下:
The judgment methods of the quality of DC miniature deceleration motor are as follows:
1、直流大功率电机运转至温升稳守时,停机用万用表丈量绕组的电阻,通常为零点几到几欧姆;
1. When the DC high-power motor runs to a steady temperature rise, the multimeter is used to measure the resistance of the winding, usually from zero to several ohms.
2、用手旋转电机,假如感受有显着较大的阻力,阐明电机内部有短路点;
2. If the hand-rotated motor has significant resistance, it is clarified that there are short-circuit points inside the motor.
3、将正负极连接起来,用手拧的时分会有很大的阻力,阐明线路正常,不然内部有断路点;
3. Connecting the positive and negative poles together, there will be great resistance when the poles are twisted by hand, so as to clarify that the line is normal or there will be breakpoints inside.
4、通电转变时调查换向火花,没有火花最佳,有星星点点的火花为杰出,火花连成线为差,有环火表象就不能用了;
4. Investigate the reversing spark when the power is switched on, no spark is the best, sparks with stars and dots are outstanding, sparks are connected in a bad way, and ring sparks can not be used.
5、加上额外电压,丈量转速,与标明转速差错不该超越10;
5. Add extra voltage to measure the speed and indicate that the error of speed should not exceed 10.
6、运转至温升安稳后,电机表面温度不要超越80摄氏度,假如超越这个值,阐明电机的温升不过关;
6. After running to a stable temperature rise, the surface temperature of the motor should not exceed 80 degrees Celsius. If exceeding this value, the temperature rise of the motor can not be cleared.
7、加上1.2倍的额外电压,运转2分钟,调查有无反常。
7. Add 1.2 times the extra voltage and run for 2 minutes. Investigate if there is any abnormality.
