The axial flux PM motor is an attractive alternative to the cylindrical radial flux motor due to its pancake shape, compact construction and high power density. These motors are particularly suitable for electrical vehicles, pumps, valve control, centrifuges, fans, machine tools, robots and industrial equipment. They have become widely used for low-torque servo and speed control applications [172]. Axial flux PM motors also called disk-type motors can be designed as double-sided or single-sided machines, with or without armature slots, with internal or external PM rotors and with surface mounted or interior type PMs. Low power axial flux PM machines are usually machines with slotless windings and surface PMs.
