For some DC motors after overhaul, we need to check the polarity of the winding and the correctness of the connection; Check the correctness of the connection between the main pole and the commutator pole windings; Check the correctness of the connection between series and shunt windings (or between each shunt windings); Here is a small series with Senli motor to understand the next.

When measuring and measuring the insulation resistance of the winding to the housing and between the windings, in addition to measuring the insulation resistance of each winding to the housing and between each other, the insulation resistance of the armature winding between the wire hoop and the commutator, between the commutator tight ring and the commutator plate, and between the brush holder and the housing (the brush should be lifted at this time) is also measured.
The insulation resistance value should not be lower than the value calculated in the following formula, that isR=UN/(1000+PN/100), in the formulaR- Insulation resistance (MΩ);UN- Motor rated voltage (V);PN- Motor rated power (KW);
The DC resistance of the winding is measured by a double-arm bridge. The measurement should be carried out three times, the arithmetic average value is taken, and the ambient temperature is measured with a thermometer;
inDc motorIn the case of correct wiring of each winding, in order to ensure good operation performance, the brush must be placed on the geometric neutral line position; If the winding is replaced, the commutator is repaired, or there is doubt about the insulation of the winding, the winding and the commutator are subjected to voltage test against the housing, and the voltage test is carried out between the windings;
The general maintenance of the DC motor can not be carried out load test.

Long axis torque motor products, suitable for winding and winding scenarios, can be customized for different industry scenarios, to meet the requirements of use. This product produced by Senli has the characteristics of reasonable structure, high efficiency, good characteristics and long service life.
Shengzhou Senli Motor19Old motor manufacturers, with a number of their own motor production lines, from the shell, shaft, rotor, stator are independent production, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports. From the shaft machining to the whole machine assembly are completed independently. Truly realize factory direct sales.
Senli motor products are used180°High temperature resistance all copper coil material, torque motor products can be used with different rotors (ordinary rotors/Steel rotor), rotor of different motor characteristics are different, we from the shell, shaft, rotor, stator are produced by the independent, all products are the use of professional product quality supervision and testing equipment full inspection factory, can provide testing reports.
