  • Purpose The purpose of this paper is to simulate a pseudo direct drive (PDD) by using permanent magnet arrays.

    Design/methodology/approach A 2D finite element model of the PDD was built. The static magnetic torque on air-gaps was obtained by Coulomb’s virtual work method using Ansys Maxwell software. To simulate the relative movement between input rotor and output rotor, two movement bands were applied.

    Findings The PDD’s torque relation was proved. The PDD simulated presents low cogging torque.

    Practical implications The manufacturing steps and materials applied in a construction of a coaxial magnetic gear, PDD’s main component, are presented.

    Originality/value The value of this paper is to present the numerical techniques applied to simulate a PDD and the manufacturing steps and materials applied in a construction of a coaxial magnetic gear.
