Abstract
A band saw in which a continuous, electrically conductive band having cutting teeth along one edge is mounted about spaced apart support pulleys. A linear induction motor drives the band about the pulleys; the motor has a stationary induction field system as the primary driving element of the motor, mounted in operative relation to the band to drive it about the pulleys, and the band itself constitutes the motor armature.
Claims13
A linear motor driven band saw comprising a continuous, electrically conductive band carrying a plurality of cutting teeth along at least one edge,
- a pair of spaced support pulleys about which the band is mounted for continuous motion, and
- a linear induction motor for supplying power to drive the band saw, said motor comprising a stationary induction field system as the primary driving element of the motor, which stationary induction field system is mounted in operative relation to the band to drive it about the pulleys, and the band itself as the secondary driven element of the linear induction motor, said band being driven directly by induction forces established in the stationary induction field system.
