Note
Motor unit MTR-DCI-62-...-G22 can generate torque peaks
of up to 37 Nm at a peak current of 20 A in the start-up
phase.
• Make sure by calculating the dynamic loading that
the maximum safe shaft output torque for the gear is
not exceeded even in the start-up phase (e.g. by reduc-
ing the load).
Use the thread on the front of the gear (see Fig. 2/2) when
mounting the MTR-DCI to a mechanical drive fixture (machine
frame).
• In order to minimise the shaft offset: position the axis with
the aid of the centring diameter (D1 or D3, see Tab. 2/1)
relative to the rotary axis of the mechanism to be driven.
• Fasten the motor unit with 4 screws and tighten the
4 screws with the specified tightening torque.
Motor unit type MTR-DCI-32 has a total of 6 threads for
different motor mounting variants (axial, parallel). In each
case, only 4 screws must be used.
