Net conveyor motor common cause of the problem, the use of the extensive network of belt conveyor is very wide, will also appear in the use of some of the problems, and now for your detailed description of the motor problems. Mesh belt conveyor is mainly composed of stainless steel mesh belt, drive chain, motors, sprockets and related accessories, of which the motor is more easily damaged, electrical heating, overheating is a common problem, here we list 21 reasons for motor heat. 1, 2 at room temperature is too high, poor heat dissipation 3, 4 overload, overvoltage, undervoltage or voltage unbalance 5, frequent starts and stops or frequent reversing 6, phase 7, blocking the fan inlet and outlet bad or 8, bearing in oil 9 Mechanical stuck stall 10 Excessive load inertia is too long start-up time 11, 12 inter-turn short circuit, internal wiring of new motor 13 is wrong, wrong wiring star delta 14, delta or even a buck from the start load restart a long time or not functioning properly due to failure to convert 15 of 16 motor damp, squirrel-cage induction motor broken rotor bars 17, wound rotor induction motor winding resistance unbalance disconnected or 18, the rotor sweep chamber 19, power harmonics is too large, for example, near a large rectifier equipment, high-frequency equipment, 20, several repairs of motor core flux decreases 21, some poor motor winding process Ning County grand network chain Manufacturing Co., Ltd.
