Hoyer Electric Motor TYPE2E2-280S-4 – 75/90 kW, 400/690V

The Hoyer Motors TYPE2E2-280S-4 Electric Motor is a premium industrial motor designed for high-demand mechanical drive systems. With a power output of 75 kW at 50 Hz and 90 kW at 60 Hz, this motor operates on a dual-voltage configuration of 400/690V, making it highly adaptable for global installations.

It delivers a rotational speed of 1475 RPM at 50 Hz and 1770 RPM at 60 Hz, optimized for efficient performance in industrial and mechanical applications. The power factor of 0.9 reflects strong electrical efficiency and load handling.

While the mounting type is not explicitly stated, it is likely foot-mounted (B3), and the cooling system is assumed to be TEFC (Totally Enclosed Fan-Cooled) for optimal heat dissipation and operational protection. The motor is expected to have an IP55 ingress protection rating, suitable for dusty and damp environments, and an insulation class of F, supporting higher temperature tolerances.
