Synchronous motors.
Hide thumbs


1FK702☐ to 1FK710☐ synchronous motors are available ex factory (SIEMENS) complete
with flange-mounted planetary gear.
The gearboxes assigned to the individual motors and gear ratios
motor/gearbox combinations are listed in the selection 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 must be designed with keyless motor shaft end, degree of
protection IP65 and anthracite paint finish for mounting onto the gearbox.
