Operating Manual DUM/F6-Servomotors
The servomotors of the DUM/F6 series are 6- or 8-pole perma-
nent-field synchronous motors with a sine-wave induced volt-
age. A new compact coil technique ensures a high power den-
sity of the motors.

Drive end
In DIN EN 60034-7, the two ends of a motor are
defined as follows:
DE:
Drive end of the motor
NDE:
Non-drive end of the motor
When the motor terminals U1, V1, W1 are connect-
ed to a supply voltage L1, L2, L3 (with this same
phase order) the motor rotates clockwise when
viewed facing the D-end.
