1300KW Large Synchronous Motor For Blast Furnace Blower IEC GB

T5000 1300KW Large Scale Synchronous Motor For Blast Furnace Blower

Structure description
Synchronous motors have various structures: in addition to the general double bearing seat structure, there are also full suspension, shaftless, bearing seatless structure, half suspension, single bearing seat structure; movable stator structure; collector ring with protective cover, positive Pressure-ventilated safety structure; round and box-type structures, bearings can withstand biaxial thrust and can run forward and reverse, etc.; self-ventilation cooling, horizontal and vertical installation; thyristor excitation structure with slip ring and brush, There are also brushless excitation structures. Voltage levels are 380V, 3kV, 6kV, 10kV, etc. The motor protection type has various protection types from IP00 to IP54.
The frame, end cover and bottom plate of the synchronous motor are all made of steel plates. Both the stator and the bearing are equipped with temperature measuring elements, which can monitor the temperature of the motor. The rotor adopts salient pole-type magnetic poles. Fans are installed at both ends of the yoke. The cooling air enters from the end caps at both ends, enters the rotor core, and escapes to the air outlet of the machine base through the stator radial ventilation slots. The cooling effect is good. There are also duct, half duct ventilation, air-water cooling and air-air cooling types; bearings include end cover sliding bearings, seat sliding bearings (pressure oil circulation cooling), and end cover rolling bearings (grease lubrication, etc.).

Model Description
T-------Synchronous motor
TK-------Synchronous motor for air compressor
TL------Vertical Synchronous Motor
TKK-----synchronous motor with air-air cooler

This series of motors is of horizontal structure, which has the characteristics of high efficiency, large out-of-step torque, low vibration, and convenient installation and maintenance. The stator is generally an integral structure, which is impregnated with F-class VPI solvent-free paint under vacuum pressure, so that the stator has good insulation performance and reliable mechanical performance, and can withstand the impact of electromagnetic force during startup. The rotor is of salient pole structure, the magnetic pole iron core is made of high-quality cold-rolled steel plates, and the full damping structure is adopted, so that the motor has good starting performance and damping ability.
