After the motor arrived at the factory, the city's motor technician immediately disassembled the motor and inspected it. At the same time, the technician was assigned to the user's unit to view it. The test data showed that the DC resistance, insulation resistance, and rotor winding voltage drop were all within the normal range.
In line with the purpose of being responsible to the customer, Shiyi Motor held a special meeting. Based on the inspection results, relevant information provided by the user and past related repair experience, it was preliminarily judged that the rotor winding may have over-current and trip due to soldering or desoldering. With the consent of the customer, the rotor of the motor was further dismantled and found to be de-welded at various locations. By agreeing with the customer, the solution for the rotor to replace the windings was determined.
The customer expressed his appreciation for the serious and responsible attitude of the city's motor, accurate judgment and superb motor repair technology.
Recently, Zhonghai Industrial City No.1 Motor Co., Ltd. undertook a large-scale repair project of 8400-4/1500 8400KW 10KV synchronous motor. The motor is the main equipment for a steel mill in Shandong Province. It trips several times during operation, and the trip time interval is shortened. The customer can't find the reason.
