The time‐stepping finite element method for the analysis of the electromagnetic and electromechanic transients in the control motor with the drag‐cup rotor has been presented. The magnetic field is assumed to be two dimensional and the coil ends in stator winding have been treated as concentrated resistance and inductance elements. The mathematical model of the considered phenomena consists of: (a) field equations, (b) equations which define the scheme of stator winding connection, and (d) equation of motion of the rotor. The equations of this model have been solved simultaneously. The special attention has been paid to the accuracy of the electromagnetic torque calculation. The influence of the nodal density on the results has been investigated.
