One of the best ways to judge the DC geared motor

1. Connect the positive and negative poles, and when the hands are tightened, there will be great resistance, clarifying the normal circuit. Otherwise there are internal break points;

2. Rotate the motor by hand. If there is significant resistance, feel that there is a short circuit inside the motor. (The change is steady and normal);

3, when the power is changed, investigate the reversal spark, no spark is best, there are sparks of the stars are outstanding, sparks are connected into the poor, there is a ring of fire can not be used; (the number of life will be shortened sharply)

4. When the DC high-power motor is operated until the temperature rises and remains stable, the multimeter is used to measure the resistance of the winding. Usually zero to several ohms;

5, after the operation to the temperature and stability, the motor surface temperature should not exceed 80 degrees Celsius. If you exceed this value, clarify that the temperature rise of the motor does not pass;

6, plus additional voltage, measuring speed, and marked speed error should not exceed 10;

7, plus 1.2 times the extra voltage, run for 2 minutes, investigate whether there is abnormality;

8, DC high-power motor with a multimeter to measure the voltage between the commutator, if there is no between the two slices of the same voltage between the rules, clarify the winding is normal.


I hope that the above energy can help you and help you choose a good quality DC Gear Motor!
