Product Description:

The AKM22G-EFB2C-01 is a brushless AC servo motor manufactured by Kollmorgen and supplied within the AKM Synchronous Servo Motors series. It serves as a compact rotary actuator for positioning, speed, and torque control on automated machinery such as pick-and-place heads, indexing tables, and packaging axes. When connected to a compatible servo drive, the motor supports closed-loop operation with fast response and stable motion control. Its compact format also suits machines where moving mass must stay low and repeatable motion is required through frequent start-stop cycles.

The motor has a frame dimension of 58 mm, giving it a small cross-section for tight machine frames. Within that housing, rotor length index 2 pairs with winding designation G, giving the motor electrical characteristics suited to compatible AKD drives. A normally engaged 24 V holding brake is fitted to lock the shaft during power-off events and help prevent drift on vertical or load-bearing axes. Power and feedback cabling are routed through two SpeedTec-ready connectors, and the keyed twist interface helps speed installation while minimizing wiring errors. This arrangement also helps keep cable exits organized where clearance around the motor body is limited.

Position data are delivered through the proprietary SFD feedback system. This encoder outputs 4 lines of digital signal and reports absolute position within one mechanical revolution. Its single-turn inductive sensing avoids batteries and reduces sensitivity to magnetic fields. The encoder is listed as Size 10/15/21 in this configuration, and the front bearing region is supplied with a shaft seal. Integrated feedback also helps the paired drive establish rotor position quickly at startup and maintain stable commutation at low speed. That sealing helps the motor operate in light washdown or oil-mist areas without requiring separate external sealing hardware.
