> Mark II C with external Kelly KBL 301 motor controller on heat sink with powered fan. 24v-48v 3kw-5kw output at 800-1,500rpm. More details... |

The AMeP Mark II C motor is designed to replace small internal combustion engines in sailboats up to 35 feet and 15,000lbs displacement. Designed with a sealed external controller, the motor is fully enclosed in a sealed aluminum housing. The housing is the same structural housing as the Mark II B. Additional space provisions will need to be made for the external controller module. The motor unit contains a brushless, permanent magnet variable speed motor in a watertight housing, operating at low speed and high torque to be coupled directly to an existing prop shaft. Auxiliary engines using a direct drive transmission have proven to work well with the direct drive electric motor. Auxiliary engines with reducing transmissions will require prop re-pitching to achieve the best result. Included external components required for operation consist of a 5k Ohm waterproof potentiometer for speed and direction selection, and a sealed switch for controller logic power. Additional meters can display current, voltage and temperature conditions, but are not included, and are not required for routine installations. The Mark II C motor weighs 54 pounds, including sealed controller module. All motor/controller wiring is included, as well as sufficient wire for most helm installations. Customer supplied items required for installation include one or two rigid two-piece shaft coupling, battery cables to the controller module, batteries and a charging system. The controller current limit and speed can be adjusted after installation. This can reduce prop cavitation at low speed, and limit current draw at high speed (ensuring economical battery discharge). |

Mark II B with internal motor controller. Running at 24v |
|
Designed as a drop in replacement for the Atomic 4, Universal diesel, Yanmar 1GM and similar engines. Rated at 2kw at 24 volts, at up to 80 amps with motor controller built into the dry-vented aluminum case. Included external components required for operation include a 5k Ohm waterproof potentiometer and two waterproof switches for controller logic, power and forward / reverse direction. The motor unit is a combination of a motor and a controller housed in the same enclosure. This eliminates external connections from the motor to the controller, allowing for the complete unit to be sealed against liquid intrusion. A small vent, constructed with a Teflon membrane, allows dry air to slowly enter and exit the motor housing to equalize atmospheric pressure against the shaft and wire seals. The vent is rated for 4.3 psi of direct water pressure, about ten feet of submersion. The motor will not suffer adverse effects if operated partially submersed, splashed, or washed. The motor enclosure is not rated for extended submerged operation.
Maintenance of the motor is not required. Remove salt deposits from the case with running water to allow for proper cooling. The motor does not require any routine service. The thrust bearing can be replaced by removing the front cover screws and cover. Bearing life is predicted in excess of 10,000 hours mean time between failures. Replacement is simple, but highly unlikely. Replacement 3205 bearings are available from most alternator shops, AMeP , and the internet. |
