Planetary Gearbox
Series SP+
5.2.1.3 Integration
1FT602 and 1FT613 naturally-cooled motors can be supplied ex factory (SIEMENS) com-
plete with flange-mounted planetary gearbox.
The gearboxes assigned to the individual motors and gear ratios i available for these motor/
gearbox combinations are listed in the selection table. When making a selection, the maxi-
mum permissible input speed of the gearbox must be observed (this is the same as the maxi-
mum motor speed).
The motor/gearbox combinations listed in the selection tables are mainly intended for cyclic
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.
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.).
1FT6 synchronous motors should be selected as follows:
• With plain motor shaft end
• Radial eccentricity tolerance N
• Vibration severity grade N
• IP65 degree of protection (for 1FT602: IP64)
