For a single-phase motor, connect one probe to ground and measure the resistance of the motor’s starting, running, and common windings. The resistance should be infinite or close to infinite. If there is no resistance or the resistance is very low, it indicates that the motor is faulty. Then measure the resistance of the three … Read more
Many electricians habitually use a shake meter to measure the condition of motors in their daily work. This is undoubtedly a common and relatively safe testing method. Today, I will share how to use a multimeter to measure the condition of a motor, so that if a shake meter is not available, you can still … Read more

To check if the water pump motor coil is burned out using a multimeter, you need to measurethe continuity between the coil windings,short circuit conditions, andinsulation resistance. First, determine whether the motor is a three-phase or single-phase motor. The resistance values of the three-phase motor windings are the same, while the resistance values of the … Read more

Click on the blue text to follow me! The motor is the most common driving power device in our production and daily life. For example, common toys, fans, water pumps, etc., all have motors. Apart from those that are obviously burnt out, sometimes the motor’s exterior does not show visible damage. How can we determine … Read more
