  • Electric motor
    Patent number: 6909215
    Abstract: An electric motor comprising a shaft 300 on which is mounted n motor modules (where n is an integer). Each motor module consists of two generally disc-shaped rotors 302 having a coil 304 sandwiched between them. Each rotor/coil module is separated from the adjacent module by an insulative spacer element 306 and a PTFE disc 308 which is mounted on the shaft 300 concentrically with the rotors 302 and the coil 304. The axis about which each coil 304 is wound is substantially in line with the axis of rotation of the respective rotors 302.
