Masson Innovative Propulsion has started to develop and commercialize a new range
dedicated to the specificities of electrical propulsion: the “E” products. Advantages of this
configuration are countless: the weight is reduced, the gearbox less expensive, and the
maintenance is made easier as there is no clutch to take care. Less parts, less costs and
increased lifetime. For these products, we advise to use a frequency converter to prevent
overtorque.
The E-range is a new type of gearbox, but it is heavily based on the standard design reverse
gear, resulting in a very high parts commonality and proven reliability. The EM540 was fitted on
several inland waterways vessels and electrically driven pusher tug, notably with a Danfoss PMmotor rated at 700 kW @1800 rpm :
