ENERGY SAVING FLAT LINEAR INDUCTION MOTOR IN THE DRIVE OF MILLSTONE MILL
A flat linear induction motor (FLIM) in the millstone mill (MM) drive is considered. The variants of technical solutions of MM with FLIM are offered. It is concluded that the use of the FLIM in the drive of the MM allows not only to smoothly adjust the velocity and torque of the millstones, but also to prevent the sticking of flour in the working area of the millstones due to the presence of edge effects in motor. The mathematical model of the drive is composed with the possibility of solving by analytical methods. The mathematical model has a solution in the Matlab object-visual modeling environment. It has been established that the force of viscous friction exerts the greatest resistance force on the grinding process. The dry friction force with a small millstone diameter (0.2 m) does not have a significant effect on the rotation frequency of the mill.
