The direct axis refers to the axis in a synchronous machine where the magnetic field is aligned with the rotor’s magnetic field. In terms of a rotating magnetic field, it is the direction in which the rotor produces maximum torque. In the context of electrical engineering, it is crucial for analyzing and controlling synchronous generators and motors, particularly in the dq (direct-quadrature) transformation used for simplifying the analysis of AC machines. The direct axis contrasts with the quadrature axis, which is perpendicular to it.
