Integration
1FK702⃞ to 1FK710⃞ synchronous motors can be supplied ex works (SIEMENS) complete
with a flange-mounted planetary gearbox.
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 cyclic
operation S3 - 60% (ON period ≤ 60% and ≤ 20 min). Reduced maximum motor speeds and
output torques apply for use in S1 continuous duty (ON period > 60% or > 20 min).
The gearbox temperature may not exceed 90 °C
1FK7 synchronous motors should be designed with keyless motor shaft end/radial
eccentricity tolerance N, degree of protection IP65 and anthracite paint finish for mounting
onto the gearbox.
