Abstract: A method and device for controlling the torque of a brushless DC motor used in an electric motorcycle, in which a single current loop is employed to obtain a feedback current by a current detector from a DC bus which simplifies the construction of the circuit scheme. The device of this invention operates by two input signals; one of them is a torque command signal to generate a positive torque of the motor, and the other is brake command signal to generate a negative torque of the motor so as to operate a control brake command and to store the energy generated during a braking operation into a battery of the motorcycle, as well as to stop the rotation of the brushless DC motor within 120.degree. of its electrical angle of reversed rotation.
