The synchronous motor of the ball mill is a horizontal three-phase salient-pole synchronous motor. The installation method of the motor is horizontal installation. The outer casing of the motor has a circular structure, the protection grade is IP20, and the cooling mode is open ventilation cooling. The stator of the ball mill synchronous motor is made of public cooling and rolling non-oriented silicon steel sheets, which are laminated after being punched. The frame is a structurally strengthened steel plate welded structure that effectively avoids the effects of natural frequencies. The stator winding wires of this series of synchronous motors are made of F-grade self-adhesive double-glass-coated iodized film wrapped with flat copper wire. All joints and connections of the stator windings are made of silver brazing (copper wire) or argon arc welding (aluminum wire). The stator windings of this series of motors adopt star connection method, and 6 line ends are drawn out. The main lead ends are marked U1, V1, W1, and the neutral point leading end marks U2, V2, W2. The end of the stator coil is fastened with a polyester sleeve, and is tightly integrated with the end hoop and the support member (insulating member). It has reliable insulation performance and strong anti-vibration and moisture resistance. And through the overall VPI dipping process, the temperature rise of the motor is reduced, and the performance index and operational reliability of the motor and insulation are improved. After the VPI, the coil and the iron core are integrated, the bonding is firm, the mechanical strength of the whole winding is obviously enhanced, and the motor is greatly improved in moisture resistance, water resistance and environmental pollution resistance. Product Name: High Voltage Ball Mill Synchronous Motor Rated voltage: 6000V/6600V/10000V/11000V Capacity range: 350 kW ~ 5000kW Rated frequency: 50Hz, 60HZ Cooling method: IC01 Quota: S1 Synchronous speed: 150-187.5r/min Insulation class: B Temperature rise level: B Connection: Y Protection level: IP00/IP21 Power factor: 0.9 (leading) Excitation mode: static thyristor (other excitation methods can also be made) Altitude: no more than 1000m This large-scale high-voltage synchronous motor is suitable for use in environments where the ambient air temperature does not exceed 40 ° C and there is no serious dust, the minimum ambient air temperature is -15 ° C, and there is no corrosive and explosive gas in the air (which can also be made into a damp heat or high-altitude motor).
