Product Description:

The AKMH53H-CNKNCA3K is a servo motor manufactured by Kollmorgen for the AKM Synchronous Servo Motors series. It is an AKM synchronous servo motor for washdown production lines where rapid, accurate torque delivery is needed. When paired with a digital drive, the motor delivers tightly regulated motion that supports indexing, sealing, and coordinated multi-axis tasks in food, beverage, and pharmaceutical equipment. It is suited for axes that must start and stop frequently while maintaining repeatable positioning.

At a winding temperature of 100 °C, the motor maintains a continuous stall torque of 9.45 Nm, and each ampere of phase current produces 1.62 Nm/Arms through its torque constant, allowing the controller to predict load response accurately. Internal copper resistance from line to line is 2.1 ohms, which influences thermal dissipation and current loop tuning. A rotor inertia of 9.12 kg-cm² balances acceleration demands with stability, and the rotor length index is 5. Rated speed reaches 6000 rpm, and single-turn SFD3 feedback supplies 24-bit resolution with ±8 arc-min accuracy. The feedback system also supports accurate position tracking during start-stop operation. The motor is supplied with a 3 m hybrid power and feedback cable to simplify cabinet wiring.

The stainless housing has an IP69K protection rating, permitting high-pressure sanitation without extra enclosures. Installation follows an IEC 130 face mount pattern; the bolt circle is 130 mm, the pilot diameter is 110 mm, and a keyed shaft measuring 24 mm in diameter and 50.0 mm in length transfers torque to couplings. The total length from the flange to the rear connector is 249.4 mm, so the motor can fit compact frames while still allowing radial cable exit. The radial cable exit can help when space behind the motor is limited by guards or machine framing. The keyway helps prevent slip under load, and the face mount helps keep axial runout within tolerance.
