What causes the motor to trip during startup?
2024/1/4
Electric motors are essential components in many devices and have a wide range of applications. At the same time, motors can also encounter many problems that trouble users in their normal applications. Among them, the problem of tripping during motor startup is relatively common. Today, the editor will provide an answer to the problem of tripping during motor startup. Let's analyze the reasons for this phenomenon and find solutions based on the factors, In this way, when the motor trips, everyone can solve the problem well, reduce losses, and solve the problem in a timely manner. Let's take a look at the relevant knowledge together.
2. If the insulation of the motor is qualified, it may be due to a lack of phase in the power supply, imbalanced power supply voltage (significant difference), broken wires or poor contact in the motor or motor wires, etc., which need to be investigated and resolved one by one.
3. Check if the motor is leaking electricity. In the absence of an instrument, simply insulate the motor from the ground, connect a live wire to the winding, and use a digital test pen to test the casing for voltage and leakage. Short circuit between turns will not trip the leakage switch, but will only cause three-phase current imbalance. Short circuit between phases can cause the leakage switch to trip.
The above is the possibility of motor tripping. It is easy to find the problem and solve it based on the above reasons. Of course, if you encounter any difficulties, you can contact our manufacturer and call our hotline to help you solve the problem.
