Note
Motor unit MTR-DCI-62...-G22 can generate 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 permitted shaft output torque of the gear is
not exceeded in the start-up phase (e.g. by reducing the
load).
Use the thread on the front of the gear (see Fig. 2/2) for
mounting the MTR-DCI to a mechanical drive device (machine
frame).
•
In order to minimize 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 MTR-DCI-32 has 6 threads for different mounting
variants (axial, parallel); 4 screws must be used here.
