Integration
1FK702 to 1FK710 synchronous motors are supplied ex factor (SIEMENS) complete with
planetary gearbox mounted through a flange.
The gearboxes assigned to the individual motors as well as the gearbox ratios, available for
these motor-gearbox combinations are listed in the Selection and ordering data table. When
making a selection, the maximum permissible input speed of the gearbox must be observed
(this is the same as the maximum motor speed).
The motor/gearbox combinations listed in the selection tables are mainly intended for cycle
operation S3 - 60 % (ON time
≤
60 % and
≤
20 min). Reduced maximum motor speeds and
output torques apply for use in S1 continuous duty (ON time > 60 % or > 20 min).
The gearbox temperature may not exceed 90 °C and the maximum permissible input speed is
limited from a time perspective.
It must be ensured that the geared motors have adequate cooling through convection. The
gearbox must be able to dissipate sufficient heat through its flange.
Generally, planetary gearboxes can be used for ambient temperatures of between 0 ° and
40 °C. Temperatures down to -15 °C can be handled when special measures are applied
(mechanical design measures, appropriate selection of lubricants etc.).
1FK7 synchronous motors to be implemented as follows for mounting to a gearbox:
•
with plain motor shaft end
•
Radial eccentricity tolerance N
•
Degree of protection IP64
•
Anthracite paint finish
