Some practical techniques in motor winding repair
A 6 kV, 1000 kW high-voltage motor experienced a rotor winding to ground fault. Due to urgent production demands, there was little time to spare. After professional personnel identified the faulty coil, it was directly bypassed and removed. The motor continued operating for six months before ...Read more -
Inspection, testing and testing of motor products – Factory test
For rigid parts such as the base and end cover, as long as their shape and position tolerances and dimensions meet the requirements, problems are unlikely to occur after the entire machine is assembled. However, for other components, some quality issues may occur to varying degrees, such as damag...Read more -
Why do variable frequency motors require an independent fan?
In industrial frequency conversion speed control systems, installing an independent cooling fan for the frequency-controlled motor is a key measure to ensure stable equipment operation and extend the motor’s service life. The core objective is to address the industry-wide challenge of insuf...Read more -
Different temperature measuring devices operate on different principles for protecting motors.
The motor temperature monitoring device is a crucial overheat protection system for motors, primarily providing protection by directly measuring the motor’s body temperature. It compensates for the limitations of traditional current-based protection, which cannot detect hidden overheating i...Read more -
Vertical motor
A vertical motor is one whose axis of output shaft is perpendicular to the chassis or the transmission mechanism. Its prominent feature is that the mounting holes are centered on the output shaft and are evenly distributed around it. The vertical motor is vertically arranged on the driven mach...Read more -
Design and Operation | Prevention and Control of Shaft Current in Motor Bearings
For motor shaft current electro-erosion faults, in addition to relying on specialized mitigation equipment such as grounding rings, insulated bearings, and filtering devices, it is even more critical to establish a long-term prevention and control system from two dimensions: initial structural d...Read more -
