Fig. 1-5 Torque–current characteristics for various shaft heights
The individual characteristics of the individual 1FT5/6 and 1FK6 motor series
are combined to form ”typical shaft height ranges”. The lefthand characteristic
can be considered as the “best case” and the righthand as “worst case”.

Important
The constants are not valid (motor losses!) when calculating the neces-
sary rated– and accelerating currents.
Further, the steady–state load and the friction torques must be included
in the calculation.
Value of the induced motor voltage at a speed of 1000 RPM. The phase–to–
phase motor terminal voltage is specified.
