Operating Instructions, 05/2018, A5E44881183B AA
Mounting position
Spatial arrangement of a motor after it has been mounted
Maximum permissible speed (mechanical) n
max
.
The maximum mechanically permissible speed is n
max mech
. It is defined by the centrifugal
forces and frictional forces in the bearing.
Maximum output torque of the gearbox M
2Dyn
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 M
0
Thermal limit torque at motor standstill corresponding to utilization according to 100 K or
60 K. M
0
is always higher than rated torque M
N
.
Stall current I
0
Motor phase current to generate the particular stall torque (M
0
= k
T
• I
0
). 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 R
Str
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.
