Servo motors deliver more power for their size

Compared with everyday servomotors from other manufacturers the supplier says that these motors pack considerably higher power output for a given frame size.

Compared with everyday servomotors from other manufacturers the AKM motors pack considerably higher power output for a given frame size.

They also have low inertia rotors for high dynamic performance and exhibit extremely low cogging.

Now available from Micromech these new motors manufactured by Danaher are to be their flagship range throughout the world.

They can be supplied in seven flange sizes, standstill torque's from 0.18 to 53Nm, with a large number of winding options together with optional feedback systems that provide maximum flexibility for machine design.

A variety of options usually means long deliveries, this is not the case with the AKM motors.

Due to a special production process the delivery of different frame lengths, winding versions, flange types (IEC-NEMA-JIS), various feedback systems and connection methods, can all be achieved in much shorter lead times.

The standard versions of these motors are fitted with 2-pole hollow-shaft resolvers or can alternatively be fitted with additional feedback systems: * Smart Feedback Device (SFD, the intelligent Danaher Motion feedback system).

* High-resolution EnDat encoder.

* Comcoder (incremental encoders with commutation track).

The AKM motor case has an integrated front end bell which improves rigidity, strength, ensures motor alignment tolerances and means no seams to leak on the front mount interface.

The whole stator winding is potted and for safety the winding temperature is monitored and signaled by a PTC temperature sensor in the stator winding, vibration class ISO G6.3, insulation material is class F as per DIN 57530 and rated at 480V mains voltage (230V for AKM1x).

Hard wearing they have a powder coat body, the standard motor protection is class IP 40 and they are UR recognised as well as CE approved.

Useful for installation the mounting sockets for feedback and power connections can be swiveled.

Options include a holding brake (AKM2 - 7) and a viton shaft seal to give an IP 65 rating.

The AKM motor range sets a new standard in servomotors that are smaller, yet powerful and low priced.
