Product Description:
The AKM33H-ANM2R-00 is a brushless synchronous servo motor engineered by Kollmorgen within the AKM Synchronous Servo Motors series. As a rotary actuation element, it converts drive current into precise torque and speed for positioning tasks in packaging, robotics, and general automation cells. The unit pairs with compatible Kollmorgen servo drives and is sized for medium-power axes where compact dimensions and rapid response are priorities. This arrangement supports point-to-point moves, coordinated indexing, and steady speed control without requiring a large motor frame. Its standard customization level and smooth shaft allow straightforward mechanical integration, while the IEC flange with accuracy grade N mates to common gearheads or machine plates.
In continuous operation, the motor delivers a stall torque of 2.88 N-m while drawing 5.62 Arms. At 240 VAC, it reaches a rated speed of 5500 rpm and supplies 2.27 N-m of torque, and under light load the shaft can accelerate to 6330 rpm before voltage limits are reached. The H winding has a DC resistance of 1.96 Ω and an inductance of 4.1 mH, which influences current rise and servo bandwidth. Thermal buildup is moderated by a 20-minute time constant, and the housing has an IP54 rating that resists dust ingress and water spray. The motor is suited to duty cycles that combine sustained running with short bursts of acceleration.
During rapid indexing, the motor can tolerate 22.5 Arms and produce a peak stall torque of 10.2 N-m. Rotor inertia is 0.000085 kg-m², which supports quick reversals with limited overshoot on dynamic axes. The electromagnetic design yields a torque constant of 0.51 N-m/Arms and a back-EMF constant of 33.4 Vrms/kRPM, which helps the drive regulate current and speed. A factory-installed 24 V holding brake secures vertical loads when power is removed, and position feedback is supplied by a single-turn, 2-pole inductive resolver through dual Molex connectors. The 70 mm frame, rotor length index 3, smooth shaft, and IEC flange support straightforward mounting.
