6000KW Large Synchronous Motor

TDG 6000KW Large Scale Synchronous Motor For Blust Blower Steel Plant

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.

Technical data of TDG series high-power synchronous motor (6kV)

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. When the load inertia is unable to meet the technical requirements of the electric motor asynchronous starting, you must use frequencyconverted starting and matching the corresponding private digital excitation devices.

When motor adopts frequency-converted starting method, motor starting time must not be greater than 150 seconds
