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
reducing 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 mounting variants (axial, parallel). In each case only
4 screws should be used.
