Claim 0:
1. An axial flux propulsion system for an outboard electric boat comprising:
a control system which includes a communication system and a throttle that together direct the operation of boat subsystems;
an electrical power distribution system for storing and distributing electrical power, the electrical power distribution system including at least one battery;
a transmission system for transmitting torque, the transmission system including at least a transmission shaft, a drive shaft/leg shaft, and a propeller;
a traction system for generating torque, the traction system including a first axial flux electric traction motor/generator positioned adjacent to a second axial flux electric traction motor/generator;
the first traction motor/generator being positioned nearest the drive shaft/leg shaft;
a mounting system for supporting components of the propulsion system, the mounting system including transom mount bracket,
wherein the first and second motor/generator are coupled to the drive shaft/leg shaft which itself is coupled to the propeller;
wherein the control system directs the electrical power distribution system to increase, decrease, or suspend electrical power (including at least current, voltage, frequency, or phase) to the traction system, in response to signals from the throttle and communication system;
wherein the motor/generators can operate in unison or independent of each other as directed by the control system;
a fluid management system, the fluid management system further including:
a leg cooling subsystem including at least one leg inlet port, at least one fluid flow path, at least one intake circuit pump (705), at least one motor cooling heat exchanger, at least one motor cooling circulating pump, at least one motor cooling reservoir, and at least one leg outlet port, and
a battery cooling subsystem including at least one boat inlet port, at least one intake circuit pump, at least one battery cooling heat exchanger, and at least one battery cooling circulating pump, at least one battery cooling reservoir, at least one boat outlet port;
wherein the boat subsystems include at least the mounting system, the traction system, the transmission system, the electrical power distribution system.
