The paper deals with a synchronous motor control design. The field oriented control is assumed and it is suited for synchronous motor with permanent magnets. Current and voltage limitations are taken into account therefore a field weakening is used for reach high speed range with a most possible torque. A whole problem is solved using simulations in PC. Mathematical model of the synchronous motor...
A set of unique equations usable to calculate directly the optimum slip frequency and line voltage of a 3phase squirrel-cage induction machine with respect to maximum efficiency is deduced in this article. An operation in steady state at any requested speed and torque in a wide range is taken into consideration. The proposed calculation is especially useful for independent traction purposes. The requested...
A set of equations usable to calculate directly the optimum slip frequency and line voltage of a 3phase squirrel-cage induction machine with respect to maximum efficiency was deduced in part 1 of this article. An operation in steady state at any requested speed and torque in a wide range is taken into consideration. The requested torque, speed and an extended mathematical model of the machine based...
