Project Profiles

This is a 500W propulsion setup for paddle board. We have thoroughly tested 750 and 500w systems and they really work well. Very fun and reliable.  Battery is small and attached to the back of the board with a bungee. The remote has cruise control so you set the power and go.

We installed an electric drive system in this 30’ Catalina sailboat. It features a 2:1 reduction unit powered by a 10KW drive system with a Sevcon controller and Motenergy AC brushless motor. The LiFePo4 batteries are charged through a 500W/48V solar charging system. As a backup, there is a 2500W Elcon charger for shore power charging.

Marine EPU (Electric Propulsion Unit)


Templar Electric Boats from Kelowna BC had installed and tested several, off the shelf (and very expensive), marine drive systems. The performance and reliability were not adequate for the vessel. EAS Power was contracted to help solve this problem. After exploring available options the decision was made to build a custom solution. The Axial Flux motor from Slovenia was chosen. The major advantage of using the Axial Flux motor is that it is extremely powerful for its size and weight. Emrax motors are also used in small aircraft & race cars and are designed to directly drive a propeller. This simple layout means less moving parts and no transmission or reduction to service or break. The system was completed and tested by EAS Power and then installed in the Templar cruiser. The system is amazingly efficient, powerful and smooth with the matched high thrust propeller.
