Thorque™ is a unique Permanent Magnet (PM) propulsion motor with integrated pitch and thrust mechanism for Controllable Pitch Propeller (CPP) applications. It is the most efficient motor for converting electric power into propulsion power – noiselessly.
Thorque™ is available in single screw and twin screw configurations. It is also available in fixed pitch configurations.
The main features of Brunvoll Thorque™ add up to a unique and powerful package with
- High efficiency
- High torque from zero rpm
- Compact design
- Reduced emissions
- Robust construction
Main Propellers & Propeller Nozzles
All Brunvoll Controllable Pitch (CP) and Fixed Pitch Propeller (FP) configurations are individually designed for each particular ship. Their tailor-made blade design ensures optimum propeller efficiency with lowest possible vibration and noise levels.
Brunvoll HE nozzles are specifically designed to increase the thrust from the propeller in bollard pull conditions. They deliver up to 30% higher thrust at low speed compared to an open propeller.
All Brunvoll gearboxes are customised for the specific vessel. All materials used in the gearboxes are carefully selected to ensure the right conditions of the product.
- The gear housing is made from high quality cast iron to achieve a rigid and stiff design.
- Plain white metal bearings for pinion and bull gear shafts ensure extremely good reliability.
- The gearwheels are of the highest quality and designed with large safety margins.
- Hydraulic-operated multi-plate clutches for optimum and smooth operation of the entire propulsion system.
Control, Alarm & Monitoring Systems
Brunvoll designs and produces complete control systems for optimal operational reliability, lifespan and cost efficiency.
Brunvoll control systems are designed to suit most vessel types, from fast ferries and yachts to fishing boats, cargo vessels and offshore supply vessels. Brunvoll's innovative products and system solutions incorporate the latest microprocessor and PLC technology developed based upon Brunvoll's extensive experience.
