In this paper, we proposed a novel motor called speed-increasing type Vernier motor (SIVM). The proposed motor has a feature that the rotor rotates faster than the rotating magnetic field by setting the number of rotor salient poles smaller than the number of winding poles. In addition, we proposed an analytical method for this motor using an imaginary salient rotor and a coordinate system synchronized with the imaginary rotor. By utilizing the proposed analysis method, we demonstrate that vector control of the speed-increasing type Vernier motor is possible in the same manner as that of a general synchronous motor. Furthermore, the tests conducted on a prototype machine demonstrate the following two findings: First, the rotor of the proposed SIVM rotates 2 times faster than the rotating magnetic field, as per the principle. Second, the results of the static torque test closely align with the torque calculated from the theoretical equation.
