The DC motor inter-piece resistance tester is a special equipment for DC motor testing. It can effectively detect whether the commutator segment and the winding are welded well, and whether the windings are open or short-circuited through the detection of the resistance between the armature plates of the DC motor. This instrument uses a high-precision constant current power supply and is the first-choice equipment for the production and maintenance of DC motors.
The test of the resistance between the DC motor sheets is an effective method to detect the balance of the stator coil resistance. There are special provisions for this test in the preventive test regulations for power equipment. The inter-chip resistance tester is composed of a constant current power supply, a voltage detection circuit and a control circuit. The output current can be adjusted, the current is stable, the voltage value is displayed on the dot matrix LCD screen, and the data is directly read, which greatly improves the measurement speed.
