Product description
2.1.1
General information
The geared motors consist of a three-phase servomotor (1FK7/1FT6) with a flange-
mounted gearbox. The three-phase servomotors are supplied with mounted gearboxes.
Some models are supplied with an additional clutch.
The three-phase servomotor may be combined with all the gears /
motor adapters (clutches) described. The configuration (selection of the combination of
three-phase servomotor and gear/clutch) has to be user-related to achieve this.
Three-phase servomotors (1FK7) are permanent magnet excited, three-phase
synchronous
motors (three-phase servomotors) for operating with motor-controlled indirect a.c.
converters according to the sinusoidal current principle. The motors are intended for
driving and positioning machine tools, production machines, robots and handling
devices.
2.1.2
Gearbox
There are various models and designs of gears.
The gearing down stages reduce the usually high input speed (motor speed) to the
desired lower output speed (motor torque). This multiplies the input torque by the ratio to
the output torque, minus the reduction in the efficiency of the gear unit and with S1
operation.
