The design, construction and testing of a permanent magnet machine which has both axial and radial magnets and is the drive motor for an electric bicycle are discussed. The armature of a machine with multiple axes of magnetization must be capable of carrying alternating flux in all three-coordinate directions. Bonded iron powder has isotropic properties and its use for the core makes the motor possible. The result is that a very large magnet surface area is possible within the machine envelope, leading to high specific output per unit volume or weight.
