Turbine-electric transmission enters a turbine, where it expands down to the exhaust pressure, producing a shaft work output in the process. The exhaust is fed into the power turbine used to power an output shaft for whatever desired application. The power turbine is also connected to the electric generator, which converts mechanical energy into electrical energy. The electric generator driven by the power turbine charges the battery needed in order to drive the motor that supplies compressed air into the combustor. During cruise speed the electric motor does not have to be functioning, only the gas turbine engine is required to continue
Mabuchi Motor is the number of rotations per minute of the motor shaft when voltage is applied between the terminals with no load to the motor. No-load current is the current discharged when voltage is applied between the terminals with no load to the motor. Stall torque is when the motor rotation stalls upon increasing the load to the rotating motor, while stall current is when the motor rotation stalls upon increasing the load to the rotating motor. The physics formula E = M (electrical energy input equals mechanical energy output) demonstrates the conservation of energy principle at work in a Mabuchi
