Abstract
A hygienic drive system for a belt conveyor. The drive system has a stator rigidly mounted in a housing having an outer bearing surface that is continuous with the outer surface of mounting supports and avoids hard-to-clean nooks. A rotor assembly formed by drive wheels rotatably mounted on the outer surface of the housing or by a magnetic belt wrapped around a portion of the outer surface is rotated by a rotating magnetic wave produced by the stator. The stator and rotor can form an induction motor or a synchronous motor.
