An electric motor-in-wheel includes an armature formed of a stack of silicon steel plates and a winding wound round the stack of silicon steel plates and received within the motor casing, a flat type commutator mounted within the armature in the center and connected thereto in a flush manner so that the width and the space of motor can be reduced and the torque of motor is sufficient without the need for a planetgear assembly. A programmable control circuit connected to the armature by electric wires which are inserted through a wire hole on the wheel axle, the programmable control circuit detects the rotation speed of the outer shell of the motor so as to automatically control the motor to work or cut off power supply from the motor according to a predetermined speed range.
