BECKHOFF AM2000 - Manual (Page 11)

I.6 Options
-09- Special flanges and shafts are possible, we invite inquiries.
-J-
Radial shaft-sealing rings:
A radial shaft-sealing ring can be supplied at extra charge to seal against oil mist
and oil spray. This increases the protection rating of the shaft bushing to IP65. The
sealing ring is not suitable for dry running. When a holding brake is built in, the
motor length increases by option -J- for 10mm.
-V- Vertical mounting sockets for resolver and power connections.
-C- Cable exit with PG-glands.
-K- Mounting flange for Stöber bevel gear
-2K- Special varnish with 2-component enamel.
-426- Encoder adaptor for ROD426/ROQ425 with coupling and eccentric washers.
I.7 Selection criteria
The three-phase servomotors are designed to operate with AX2000 servoamplifiers.
Together, both units form a closed speed or torque control loop.
The most important selection criteria are:
—
Standstill torque M
0
[Nm]
— Rated speed n
n
[min
-1
]
— Moment of inertia of motor and load J [kgcm²]
— Effective torque (calculated) M
rms
[Nm]
When calculating the motors and servoamplifiers which are required, take account of the
static load and the dynamic load (acceleration/braking). Collected formulae and examples
of the calculations are available from our applications department.
