AKMThe AKM servomotors can be driven by all Danaher Motion servo amplifiers. Seven flange sizes and a large number of winding options with optional feedback systems provide maximum flexibility for machine design.

A special production process facilitates the delivery of different frame lengths, winding versions, fixing methods (IEC-NEMA-JIS), various feedback systems and connection methods, all in the shortest possible time.

The motors are mat black (powder coated).

The winding temperature is monitored and signalled by a PTC temperature sensor in the stator winding.

Compared with servomotors from other manufacturers, AKM motors have a considerably higher power output for a given frame size. The motors have low inertia rotors for high dynamic performance and they exhibit very low cogging.

 

Feedback

The standard versions of these motors are fitted with 2-pole hollow-shaft resolvers. They can alternatively be fitted with additional feedback systems:

bullet

Smart Feedback Device (SFD, the intelligent Danaher Motion feedback system)

bullet

high-resolution EnDat encoder (in preparation)

bullet

Comcoder (incremental encoders with commutation track)

Retrofitting is not possible. The length of the motor varies according to the type of feedback.

Technical Data

Nominal values at 40°C ambient temperature and 100 K temperature rise in the windings motor mounted to a reference mounting plate. Modern motors with compact designs may exhibit high surface temperatures, requiring a de-rating from the nominal values in some applications.
