Synchronous Servomotors AKM
These new servomotors can be driven by all Kollmorgen 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, flange standards (IEC-NEMA-JIS), various feedback systems and connection methods.
Power output and dynamics
Compared with everyday 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:
- Smart Feedback Device (SFD, the intelligent Kollmorgen feedback system)
- High-resolution EnDat (optical or inductive), BISS encoder,
- Comcoder (incremental commutating encoder).
Holding Brake
The motors can be supplied with a built-in holding brake as an option.
Safety
The winding temperature is monitored and signalled by a PTC temperature sensor in the stator winding.
