Abstract
A peristaltic feed pump, driven by a shaded pole motor, is provided to feed sticky, thixotropic fluids such as soaps, detergents, rinse additives, etc., to a dishwasher, chemical reactor, and the like. The shaded pole motor comprises a constant torque, A.C. portion and a D.C. electromagnetic brake portion. The net effect of the motor enables the fluid to be fed to the dishwasher by the pump within reasonable limits of linearity.
