Abstract: An automatically variable torque and speed motor for electrical tricycles is disclosed, and the motor rotor assembly of which comprises fixed rotors and rotary rotors arranged adjacently in turn along the axis of the motor shaft. Staggered pole pieces on the surfaces of the fixed rotor and the rotary rotor form a staggered angle ? along the circumference. The support of the rotary rotor comprises a revolving support ring and two fixed side discs which are respectively arranged on the two sides of the revolving support ring. An elastic compression part is arranged in the inner cavity of the revolving support ring along the revolving direction. The elastic compression part has one end arranged at the inner circle of the revolving support ring and the other end arranged on the side wall, facing the inner cavity of the revolving support ring, of one of the fixed side discs. The present invention can adjust the speed and torque according to the load situations of the whole electrical tricycle.
