Product Description:

The AKMH62H-ACKNCA1K is a hygienic stainless-steel washdown motor in the AKMH Stainless Servomotors series from Kollmorgen. It uses the AKMH6 frame size and conforms to DIN 748 / DIN 6885 T1 with an IM B5 flange mount. The IEC flange measures 186 mm in diameter with a 130 mm pilot, and a 32 mm closed-keyway shaft passes through a sealed output. Housing roughness stays below 0.8 µm, the flange uses an FDA-approved O-ring, and the 1.4404 (316L) housing resists caustic cleaning media. The motor has a 1 meter body length, rotor stack length code 2, mineral-filled PTFE stator insulation, and a pre-assembled cable for direct connection to an AKD drive.

During steady operation, the motor delivers a 10.6 N·m continuous stall torque while drawing 5.32 Arms. Its torque constant of 2.03 N·m/Arms links phase current to shaft output, and the 142 Vrms/kRPM back-EMF value must be considered with a 640 VDC bus. Winding inductance of 25.4 mH supports stable current regulation, and the Smart Feedback Device encoder supplies 11-bit resolution for commutation and feedback. This combination suits motion systems that need controlled torque response and encoder-based position tracking in wet processing environments.

Resistive losses are influenced by a phase resistance of 3.32 Ω, and the rotor inertia of 0.00169 kg·m² supports quick acceleration and deceleration. The motor carries an IP69K protection class, allowing operation under high-pressure washdown conditions while the stainless housing and sealed flange help protect internal parts. It is supplied without a holding brake, so standstill holding depends on the servo system rather than a mechanical brake. Overall mass is 19.6 kg, which keeps the unit substantial enough for rigid mounting without making the assembly unusually large for its frame. The IM B5 mounting format also supports straightforward integration into equipment that uses standard flange geometry.
