Product Description:

The AKMH62L-ACKNCA1K belongs to the AKMH Stainless Servomotors series from Kollmorgen. As a hygienic stainless-steel washdown motor, it is intended for conveyor, filling, and portioning axes that must tolerate high-pressure cleaning while maintaining precise rotary positioning. Its IEC flange mounting and closed keyway shaft let it couple directly to load equipment, and the Smart Feedback Device interface links rotor position data to an AKD drive through a pre-assembled cable.

The motor can reach a top speed of 6000 rpm, giving machinery the headroom to follow rapid production cycles. During transient loading, it produces up to 27.8 Nm of peak torque while drawing a peak current of 36.0 Arms; this pairing helps determine inverter sizing for acceleration events. At a stabilized winding temperature of 100 °C, the continuous stall capability is 10.5 Nm, so it can hold product flow steadily without overheating. A torque constant of 0.94 Nm/Arms links commanded current to generated torque, which helps with closed-loop tuning. With 5.4 mH of phase inductance and 0.71 Ω of resistance, the electrical time constant balances fast response with controlled ripple, and an 11-bit feedback resolution supports fine velocity trimming.

Environmental features match clean-in-place requirements. The housing is machined from 1.4404 (316L) Stainless Steel and sealed to IP69K, allowing direct contact with caustic foaming agents and high-temperature water jets. An FDA-approved O-ring secures the 186 mm flange, and the shaft interface is protected by an IP69K seal on the 32 mm diameter. The embedded Smart Feedback Device (SFD3) carries both position data and motor nameplate data over a single pair, eliminating separate encoder cables. Surface roughness is held below 0.8 µm to discourage bacterial retention, and the 130 mm pilot diameter centers the frame in DIN 748 and DIN 6885 T1 compliant mounts.
