High-Speed Synchronous Motor
170TD50Y80
Ultra-high-speed 80 kW permanent magnet synchronous motor. 50,000 r/min with P4/P2 ceramic hybrid bearings and advanced dual cooling for extreme-performance industrial drive applications.
170TD50Y80 High-Speed Synchronous Motor
The 170TD50Y80 is a state-of-the-art ultra-high-speed permanent magnet synchronous motor designed for the most demanding high-speed industrial drive applications. Delivering 80 kW of continuous power at an exceptional 50,000 r/min, this motor represents the pinnacle of high-speed electric motor technology. The permanent magnet synchronous design provides superior efficiency, excellent power density, and precise speed control compared to asynchronous alternatives.
P4/P2 ceramic hybrid angular contact ball bearings with silicon nitride (Si3N4) rolling elements are essential for reliable operation at 50,000 r/min, minimizing centrifugal forces and heat generation. An advanced dual cooling system integrates a high-capacity water jacket for the motor stator with a precision oil-air lubrication and cooling circuit for the bearings. This combination ensures stable thermal conditions during continuous high-speed, high-power operation. Housed in a 170mm diameter frame and weighing approximately 280 kg, the 170TD50Y80 is engineered for integration into high-speed electrospindle drive systems, advanced test rigs, turbo-machinery, and specialized industrial equipment where extreme speed and power density are primary requirements. Every motor is dynamically balanced to G0.4 grade and undergoes comprehensive run-out testing before shipment.
