In daily electrical maintenance or motor inspection work, determining the condition of a three-phase motor is a crucial skill. The multimeter, known as the “magic tool” for electrical maintenance, plays a significant role in this process. So, which setting should we use on the multimeter to assess the condition of a three-phase motor? Hello everyone, … Read more
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

1. Choose the appropriate megger: If the rated operating voltage of the motor being tested is 380 volts, we can choose a 500V megger. 2. Place the megger flat, perform a short circuit test by connecting the two probes together; if the pointer approaches 0, it indicates good condition. 3. Next, separate the two probes, … 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

1. Choose the appropriate megger: If the rated operating voltage of the motor being tested is 380 volts, then we can select a 500V megger. 2. Place the megger flat, perform a short circuit test by shorting the two probes, and if the pointer approaches 0 while cranking the handle, it indicates good condition. 3. … Read more
