Typical useful speed defined by the manufacturer. Depending on the
particular application, other useful speeds are possible (see speed-torque
curve).
Continuous torque that can be output at the rated speed in operating
mode S1.
Phase current of the motor at the rated speed and load with rated torque,
specified as root-mean-square value.
