The Switch, a leading supplier of permanent magnet (PM) machines for marine applications, has launched the PMM850M PM machine, a compact, high-efficiency solution designed to help shipowners lower fuel consumption, reduce emissions and decrease operating costs. Deliveries are scheduled to begin in 2027.

Key advantages for customers:

Reduced fuel consumption thanks to high electrical efficiency.

Lower CO₂ and NOx emissions, supporting compliance with environmental regulations.

Minimal maintenance requirements due to the brushless design and simplified cooling system.

High reliability supported by a proven PM technology platform with more than 5 million operating hours and no failures causing vessel downtime.

Compact footprint, enabling greater flexibility in vessel layout and installation.

Quieter operation and compliance with increasingly strict airborne and underwater radiated noise regulations thanks to the absence of external cooling fans.

Filling a strategic market gap

Designed for shaft generator and propulsion applications, the PMM850M targets vessels operating in the 500 kW to 1.5 MW power range, filling a gap at the lower end of The Switch’s PM machine portfolio.

The launch addresses a growing market need for a smaller and more cost-efficient machine for vessels where even the PMM1000M may be too large to install.

“We often see that space in the engine room is extremely limited, especially in vessels with narrow hull designs. Our goal was to develop a compact,…
