Recently introduced by Micromech the AKM has 7 flange sizes and a large number of winding options with optional feedback systems provide maximum flexibility for machine design but due to a special production method they are produced in the shortest possible time. The clever process even facilitates the delivery of different frame lengths, winding versions, fixing methods (IEC-NEMA-JIS), various feedback systems and connection methods without increasing lead-times.

The mat black (powder coated) motors come in 7 standard flange sizes of 40 to 188mm (j6 fit, accuracy as per DIN 42955, tolerance class N) although on request various flange/pitch circle versions are available. The AKM has over 70 torque sizes ranging from 0.18 to 52.5Nm

For feedback the standard versions of these motors are fitted with 2-pole hollow-shaft resolvers or they can alternatively be fitted with additional feedback systems. There is either the SFD (Smart Feedback Device) an intelligent Danaher Motion feedback system, a high resolution EnDat encoder or a built-in Comcoder, which is an incremental encoder with commutation track. Retrofitting of these devices is not possible as the length of the motor varies according to the type of feedback. For safety the winding temperature is monitored and a signal sent by a PTC temperature sensor in the stator winding.

The motors insulation material is class F as per DIN 57530 therefore the range is rated at 480V mains voltage and 230V for the smallest motor.
The protection of a shaft seal is an option making the motors IP65 while the vibration is class N (DIN ISO 2373) and the shaft is machined to DIN 748, has a threaded hole and can be with or without a fitted keyway. A holding brake is available on most frame sizes.

Usefully the mounting sockets for feedback and power connections can be swivelled to suit.
