Basic motor starters, MOVIFIT® basic
Minimum effort – maximum benefit: With the decentralised MOVIFIT® basic motor starter. It is ideally suited as a reversing starter or as a dual-motor starter. For your intralogistics applications.
For efficient materials handling technology: MOVIFIT®basic, the decentralised basic motor starter, available as a reversing starter or as dual-motor starter.
Less is more: Sew Eurodrive has reduced the MOVIFIT® basic to include only the functions and features necessary, and its design means that it is the ideal motor starter for the lower function range. It covers the 4 kW or 2 x 2.2 kW power range.
The motor starter is available as a reversing starter or as a dual-motor starter. The reversing starter enables motor operation in two directions of rotation. Alternatively, you can operate the dual-motor starter with two motors that convey the material flow in one direction independently of one another. In this extremely efficient concept, 2 motors share one MOVIFIT® basic motor starter.
The energy for AC 3 x 400 V is distributed via the FieldPower® terminal from Weidmüller, which is integrated in the unit. Two sensors can be connected to the unit in addition to the drive function when using AS-Interface. These are signaled to the system controller via AS-Interface master without additional costs and the signals can then be processed in the system controller.


  • FieldPower® contact block* for energy distribution with modern and reliable connector technology
  • Simple connection and wiring technology
  • Consistent integration of power distribution components in the housing of the drive unit
  • Consistent use of standard plug connectors for control and motor connection
  • Extremely short assembly and installation times
  • When using AS-Interface, two sensors can, in addition to the drive function, be connected to the unit for direct communication with the system controller (at no additional costs)
