Electric Propulsion Motor

Electric Propulsion Motor

 

Features

The Mega-Guard Electric Propulsion Motor (EPM) is a highly efficient permanent magnet motor for ship's propulsion. The Electric Propulsion Motor is able to directly drive the propeller shaft or can be used in parallel  with a combustion engine. Electric propulsion is applied in case of requirements regarding zero emission,  better manoeuvrability and/or
less fuel consumption for vessels with large difference in sailing profile. Silent running is another application of electric propulsion in combination with Mega-Guard Electric Energy Storage. The Electric Propulsion Motor is controlled by other Mega-Guard products: High Power Inverter, Propulsion Control System, Energy Management System and/or the DC bus Generator. Various sizes of Mega-Guard EPM are available to suit all applications for full electric, serial hybrid or parallel hybrid propulsion.  

 

Full electric propulsion

The full electric propulsion uses the Mega-Guard Electric Propulsion Motor to drive the propeller shaft. Electric power is coming from the Mega-Guard Electric Energy Storage and charging is done through shore power. The AC grid for hotel load is generated from the Electric Energy Storage as well.

 

Serial hybrid propulsion

The serial hybrid uses the the Mega-Guard Electric Propulsion Motor as well to drive the propeller shaft. Electric power is coming from either the Electric Energy Storage or the DC bus Generator. Charging of the battery bank is done through the DC bus Generator or by shore charging.

 

Parallel hybrid propulsion

The parallel hybrid  propulsion system use a combustion engine and an Electric Propulsion Motor to drive the propeller shaft. The combustion engine and the electric motor are mounted in parallel in one of following ways:

  • Electric Propulsion Motor is mounted in-line with shaft
  • Electric Propulsion Motor is mounted on the gearbox via a PTI/PTO connection
  • Electric Propulsion Motor is mounted between gearbox and combustion engine

The Electric Propulsion Motor also works as generator for battery charging in case combustion engine is running.
