Product Description:

The MH-827-A-43 servo motor is produced by Kollmorgen within the M Goldline Servo Motors series. This three-phase device drives precision axes in packaging lines, material-handling gantries, and other automated stations where accurate speed regulation is needed. A frameless resolver supplies rotor position so the controller can commutate the stator windings, and the power leads terminate in a sealed terminal box for straightforward cabinet wiring.

The motor is designed to run on a line supply of 480 VAC. Under continuous duty it draws 20 A RMS/phase and converts that current into 93.5 N·m of steady torque, producing a mechanical output of 11.4 kW. A top speed of 1500 RPM lets the drive match high-inertia loads without pushing the magnetic circuit beyond its intended speed range. The 0.215 m bolt circle and 14 mm mounting holes fit standard IEC flanges, while the Interconnectron SEFA12AMREN000 connector carries resolver signals back to the drive. Because rotor inertia is only 0.0888 kg·m², acceleration times stay low, helping indexing tables reach setpoints quickly. The motor is shipped without a shaft seal, so installations that face coolant spray or oil mist must protect the nose end externally.

For intermittent moves the machine can demand up to 162.8 N·m of peak torque, which requires a momentary winding current of 40 A RMS/phase. That overload capacity covers start-ups, quick reversals, and short shock loads without exceeding thermal limits. Total housing length is 648.7 mm, leaving room for the terminal box while still fitting inside compact drive modules. The frameless resolver and the Interconnectron plug provide a dedicated feedback connection to the drive, and the absence of a shaft seal lowers friction at the motor nose. Bolt circle and hole dimensions help keep mounting alignment consistent during installation.
