Purpose: The purpose of the paper is to introduce a novel design topology for an electric motor, which has essentially none of the normal sources of magnetic alternating force. Design/methodology/approach: Two-dimensional (2D) and three-dimensional (3D) finite element methods are used to analyze the electromagnetic performance of the proposed machine. 3D integral equations are used to calculate the scalar potentials. Detailed manufacturing process and the results of the testing are presented. Findings The new design will eliminate core vibrations, slot passing frequency vibrations and torque pulsations. The motor also has the property that the external magnetic field is controllable and tunable after the construction. Social implications This approach increases the motor efficiency. Originality/value: The proposed machine has low field and vibration, so it can be used where low exterior fields are required.
