Lamb's design activities were monitored by VDMA member company Gansow and Co. GmbH, Bergkamen, Germany, a German manufacturer of professional floor scrubbers and sweepers. Gansow also evaluated the interface of the vacuum motor to the machine and provided its evaluation to the VDMA group. May. With close cooperation between European and North American manufacturers, these designs are expected to soon appear worldwide in Europe, Asia, and The Americas. For cord-operated appliances, the gains translate into reduced motor size, which saves size, weight, and material cost. The improved fan system in the AWS series was achieved through a fan and diffusion system design that previously was not cost effective.
Improved materials allow new shapes to be incorporated on an economical basis.
Better manufacturing processes have facilitated many of the mechanical changes in the fan-system configurations. Manufacturing process improvements coupled with new materials also enhance the bearing alignment, permitting higher operating speeds without vibration and without sacrificing bearing life. All of the above is supported by a better commutation system that allows for higher operating speeds.
