Product Description:
The AKM42G-ASC2R-02 is a synchronous servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. It operates as a compact rotary actuator for closed-loop position or velocity control in industrial automation, delivering precise motion when paired with a compatible servo drive and feedback interface. Coil temperature and torque constants correspond to winding code G, which matches the drive data used for current-loop tuning.
A factory-mounted 24 V holding brake secures the shaft whenever power is removed, preventing uncommanded movement on vertical or load-bearing axes. Power and feedback lines are routed through two SpeedTec-ready connectors, allowing quick, keyed coupling during installation. Rotor position is returned through a resolver, a passive electromagnetic sensor that withstands high temperatures and electrical noise. The square housing has an 84 mm face size, allowing the motor to fit machines designed for this frame class. Mechanical attachment is provided by an IEC flange with accuracy class N, offering alignment tolerances suitable for precision gearheads and couplings without additional shimming.
The resolver uses a two-pole feedback configuration, balancing position resolution with straightforward commutation for medium-speed axes. Its single-turn inductive feedback range reports absolute shaft position across one mechanical revolution without multi-turn tracking hardware. The feedback carrier uses package size 10/15/21 for its physical interface. Rotor length index 2 indicates an extended axial magnetic stack that provides higher continuous torque than the base length while keeping rotor inertia moderate. The special shaft option permits nonstandard diameters, keyways, or hollow features, allowing the motor to connect directly to custom transmission components. This shaft configuration can reduce the need for separate adapters when the driven mechanism requires a specialized mechanical interface.
