The following table provides an overview of the torques and speeds that can be achieved
with 1FW68 segment motors. The stated torques and maximum torques refer to each
individual stator segment.
Note
Dependency of the torques on the number of stator segments
Torque of entire segment motor = number of stator segments x torque of each stator
segment
Maximum torque of entire segment motor = number of stator segments x maximum
torque of each stator segment
Full complement means that the segment motors are fitted with the largest possible
number of stator segments. The number of stator segments required for the entire
segment motor depends on the torques required for the application. A full complement is
not always required.
The stated speeds are the maximum possible speeds for each diameter. The speeds are
adjusted for the individual requirements.
