Extra-low-voltage motors provide solution for machine modules

As KOLLMORGEN has transferred, energy efficiency, durability, power density and overload capability, customers will gain the benefits of permanent-field servo motors to the extra low voltage world. The new AKM DC servo motor low voltage with its 48V design was originally intended as a customer-specific solution for special areas of use.

Kollmorgen - a specialist in servo-drive technology and motion control will now offer this as a standard add-on to the AKM series, and thus as a new series product. There are many potential uses for 48VDC servo motor low voltage. The same applies to two new variants with a 24V power supply.

Size 3 AKM low voltage servo motors of 48V provides up to 300W of power at a current of 6A - sufficient, for example, for accurate drive tasks in packaging machines or for dynamic movement in autonomous transport systems.

Because the axes can briefly provide a peak current of up to 15A, the breakaway torques predominant on start-up are easily overcome, which, at the end of the day, prevents permanent over dimensioning of the drive technology. The static torque is 1.25Nm with an impulse torque of 4.1Nm. Further variants of KOLLMORGEN AKM low voltage DC servo motor include two 48V motors with less power, and two drives with windings tailored to 24V.

Thanks to its compact form, the extra low voltage servo-axis can be very easily retrofitted in existing installations and additionally allows space-saving surface mounting of machine modules with autonomous intelligence - in the form of a labelling unit, for example.
