The invention provides an electric engine, a control method, a related device, a
motor controller and an aircraft, and relates to the technical field of aircrafts. The electric engine comprises a power motor, a heat dissipation
system and a control module, a cavity is formed in the power motor, the control module is integrated in the cavity, the space occupied by the electric engine is reduced, and therefore the size of the aircraft is reduced; the control module comprises at least three integrated driving modules, part of the driving modules are electrically connected with the power motor so as to control the power motor, part of the driving modules are electrically connected with a variable
pitch motor of the
propeller so as to control the variable
pitch motor, and part of the driving modules are electrically connected with a heat dissipation motor in the heat dissipation
system so as to control the heat dissipation motor. The performance and efficiency of the electric engine are improved through unified integrated control over the power motor, the heat dissipation motor and the variable
pitch motor. And through a unified control architecture, the
system design is simplified, the development and maintenance cost is reduced, and the
maintainability of the electric engine is improved.
