Technical data
1FK7 G2 synchronous motors
130 Operating Instructions, 05/2021, A5E50907562B AA
Mounting position
Spatial arrangement of a motor after it has been mounted
Maximum permissible speed (mechanical) nmax.
The maximum mechanically permissible speed is nmax mech. It is defined by the centrifugal
forces and frictional forces in the bearing.
Maximum output torque of the gearbox M2Dyn
Maximum permissible output torque of the geared motor that may be output for a short
period of time
NDE
Non-drive end = Non-drive end of the motor
Number of poles 2p
Number of magnetic north and south poles on the rotor. p is the number of pole pairs.
Static torque M0
Thermal limit torque at motor standstill corresponding to utilization according to 100 K or
60 K. M
0 is always higher than rated torque MN.
Stall current I0
Motor phase current to generate the particular stall torque (M0 = kT • I0). Specification of the
RMS value of a sinusoidal current.
Transmission ratio i
Designates the value of a physical variable divided by another value of the same physical
variable.
Winding resistance RStr at 20° C winding temperature
The resistance of a phase at a winding temperature of 20° C is specified. The winding is in a
star connection.
