Description
The propeller is driven directly or together with a diesel engine, the motor works in the zone of higher efficiency with lower emissions, and full torque is available from the lowest speeds, which improves maneuverability compared with a purely diesel drive. The motors are used as propulsion motors in fully electric and battery systems and as traction machines in hybrids. In the Marine Solutions 2026 brochure the standard DST2 135–560 range has a power of 2–875 kW. The characteristics match the industrial series, from DST2-135 (2.7–60 kW, up to 1500 rpm) to DST2-400 (92–530 kW at 100–300 rpm, 8800–18 600 N·m rated and up to 31 600 N·m maximum torque). In a parallel hybrid the total plant power is 455–1470 kW (618–1998 hp).
How to choose
Lloyd's Register classification is held by frame sizes 315 and 400, and DNV or Bureau Veritas approvals are arranged for a specific project. Cooling is by water or oil, degree of protection IP54. Wing mount supports have feet along the housing diameter for fixing to the ship's framing. For factory equipment without marine classification take the industrial DST2 135–560 version.

FAQ
What power do the DST2 marine motors have?
2–530 kW in standard version according to the website, 2–875 kW according to the brochure. For individual projects up to 3 MW and up to 6 MW are declared.
Which propulsion schemes are they intended for?
For parallel hybrid, diesel-electric and fully electric (battery) systems, where the propeller is driven directly or together with a diesel engine.
Which frame sizes have ship register classification?
Frame sizes 315 and 400 are certified by Lloyd's Register. DNV and Bureau Veritas are agreed separately for a project.
What is the maximum torque?
Up to 31 600 N·m for DST2-400; the rated torque of this frame size is 8800–18 600 N·m.
What are wing mount supports for?
The feet are located diametrically on the outer diameter of the housing, and this is how the motor is fixed to the ship's framing.
