Product Description:

The BH-828-E-43-B3E1 is an AC synchronous servo motor produced by Kollmorgen within the Kollmorgen Goldline B and BH Motors series. This brushless unit integrates into closed-loop motion systems where precise torque delivery and speed regulation are required for axes on packaging lines, machine tools, or material-handling stations. By converting electrical power into controlled rotation, the motor forms the primary mechanical actuator in high-performance automation cells.

The motor can deliver a continuous shaft torque of 89.5 N-m, sustained without overheating when the drive supplies 39.1 ARMS of phase current. At that operating point, the rotor can maintain 3200 rpm, allowing direct coupling to gearboxes or belt drives that need moderate to high speed. Its continuous stall torque of 122.8 N-m provides the holding force available at zero speed for vertical axes or clamping stations. A line supply of 480 VAC energizes the three-phase stator windings; this voltage class matches common industrial mains and simplifies cabinet design. The winding inductance of 8.05 mH moderates current rise time, so current controllers in the drive achieve smooth torque production and limit bus harmonics.

For short acceleration bursts the electromagnetic system supports 183 N-m of peak output, and that reserve can be accessed when the amplifier sources up to 80 ARMS. A peak stall rating of 230.5 N-m is available for instantaneous load changes when the shaft is stationary. Acceleration dynamics are also influenced by the rotor’s reflected mass; an inertia of 0.0168 kg-m² lets the axis change speed rapidly while still providing stable velocity control. The housing spans 685.4 mm from flange to rear cover, providing space for the integral stator, a brake coil that accepts 24 VDC, and a terminal-box style power connection. Encoder mounting provisions are included, mating plugs are not supplied, and the design omits a front shaft seal, so external guards may be needed in fluid-rich environments.
