Advanced Marine Electric Propulsion 24v 2kW - $2500 - call to order

This direct drive brushless DC motor specifically designed to replace inboard ICEs in sailboats up to 32 feet. With an internal controller, the motor unit is sealed to 10' of temporary submersion, yet vented to dry air to maintain atmospheric pressure within the motor housing, relieving seal pressure and eliminating grease migration. The 1" keyed stainless steel shaft extends eight inches from the motor rear face to accommodate hull curvature. The shaft exits five inches up from the bottom of the motor housing, and in the center of the 9.375" width. The motor housing is 13.75" tall, 3.25" thick, and weighs 30 lbs. Mounting is achieved via four 1/2 x 13tpi tapped heli-coiled blind holes, arranged symmetrically about the drive shaft on the sides of the housing. Simple mountings can be fabricated from 2"x2" aluminum angle, or with 1/4" aluminum plates secured to both the motor and engine stringers. Wiring does not require a relay or any external battery switch. Battery leads are designed to be connected directly to the main battery. A second string can be combined with the primary string using a two position switch. Logic power is controlled by a remote switch, and consumes a mere 40mA on standby (50mA with an LED power indicator). When the logic power is off, there is no measurable battery drain. There are no exposed terminals, no additional connectors, and no external wires between the motor and the controller. With a no-load speed of 1000rpm, the motor achieves peak output at 875rpm, making the use of large efficient propellers possible. Although an aggressive prop will provide peak performance, the motor torque range is broad and efficient, making nearly any prop functional without modifying the boat.Hull speed can require 2.5kW per ton of displacement, while 70% of hull speed requires just 500w per ton (credit to the Danes for the numbers).
