The invention discloses a multi-shaft aircraft supplied with powder by a direct-current power supply, in particular a parallel speed adjusting method of a direct current motor of a multi-shaft aircraft; the multi-shaft aircraft is characterized by comprising an aircraft body, multiple electric rotor wings, a flight state computer control system, a remote controller and a direct-current power supply; and the direct-current power supply is leaded from external through a power transmission line. All driving direct-current motors are grouped pairwise, so that stator windings of the motors are serially connected to form branches; all the branches are connected with the power supply in a serial connection or parallel connection manner; the stator windings of all the motors or one parts of the stator windings are connected with a multifunctional module in parallel; the multifunctional module comprises a flight control circuit, a direct-current voltage drop circuit, a rechargeable battery, a power utilization load and a false load; and the states of all the motors are controlled and changed through changing the state of the multifunctional module. The invention provides a speed adjustment/operation control scheme suitable for a multi-shaft rotor wing aircraft, needs no complex algorithm, only needs one switch between the motors and the power supply, and is high in reliability; and a little of electric energy consumed by state control also can be efficiently used.
