Flat motors

The maxon motor range of brushless DC motors with integrated electronics features established drives EC 20 flat, EC 32 flat and EC 45 flat, but now they have in-built speed controllers, yet are almost the same size. The motors available as standard are the 2- and 5-wire versions, with an operating range of 2-50 W. The drives are suitable for use where there is minimal installation space, when long service life and constant speed are required at the same time as simple control operations.

The EC 20 flat, EC 32 flat and EC 45 flat motors with integrated electronics also reduce the user’s need for control input to the absolute minimum. Current commutation is integrated in the motor through Hall sensors, a 1-quadrant speed controller and numerous protection functions. Motors are available as 2- and 5-wire versions. In the 2-wire version, speed acts proportionately to the applied operating voltage of 10-28. In the simplest case, the drive is powered directly by the battery. The 5-wire version offers additional functionality and a wider operating range with set value input, enable and speed monitor. Current limitation, under and over-voltage switch-off plus temperature monitoring are implemented as standard in all models.
