TDG 7800KW Large Scale Synchronous Motor For Blust Blower Steel Plant
TDG series high-power synchronous motor is the special products matched with steel plants sintering fan, can be used to power huge moment of inertia of the mechanical load, such as blast furnace blower and air turbine compressor.
Motor speed is 1000r/min. Products with a reasonable structure, high efficiency, loss of torque, driving large inertia mechanical load and vibration of small, convenient installation and maintenance, and other notable features.
Technical requirements of the electric motor, without specific technical agreement, the rest are in line with the national standard GB755 of the fixed and rotating machinery performance and standards of the International Electrotechnical Commission IEC.
Electrical parts mechanical dimensions, tolerances are in accordance with standard GB1800-1804 and international standards committees ISO standards.
Asynchronous starting: when the starting mode is used, it must be voltage-reduced starting. When starting, make sure that the motor Terminal voltage between 0.6~0.7 times the rated voltage. Motor must match dedicated to the excitation devices, ensure the equipment investment and shunt excitation current strongly excited when at least 1.8 times the rated current of a multiple times.
Frequency-converted starting: when electric power is greater than 7000kW, the recommended frequency-converted starting and matching the corresponding private digital excitation devices.
Motor cooling methods for IC91W or IC81W, motor with air-water cooler, the installation type is IM7311 or IM1001, enclosure protection class IP44.Motor rotor for salient form, pole for the whole steel structure, high strength alloy steel bolt for pole and polar to ensure good contact and
can withstand mechanical stress generated during high-speed runs.
