Product Description:
The BH-824S-G-G1 is a brushless servo motor produced by Kollmorgen for the Kollmorgen Goldline B and BH Motors series. Within automated machinery, this motor converts electrical power from a matched drive into controlled rotary motion for positioning axes, feed screws, or tensioning spindles. Its compact frame and integrated thermal protection reduce additional hardware, allowing OEMs to place the unit directly on metric mechanical interfaces without separate sensors or switches.
The bus connection is rated at 565/680 VDC, matching drives that operate from rectified three-phase mains and enabling high peak torque with limited current rise. Rotor position is reported through a frameless resolver, providing absolute angle data that tolerates electrical noise. The motor has a frame size of 82 mm, which corresponds to the stator housing diameter, while the low-inertia rotor helps the servo track rapid acceleration commands with reduced overshoot. Power conductors enter through a terminal box, permitting hard-wired field connections and straightforward strain relief. Metric foot and flange patterns support accurate alignment on European machinery, and a rotor stack length code of 4 identifies the active iron length selected for this model. The G-type winding pairs with the listed voltage class so that continuous torque is obtained without excessive copper loss.
The mechanical output exits at the rear of the shaft, which simplifies tandem coupling layouts or encoder mounting in confined cabinets. Overtemperature protection is provided by a built-in thermostat that closes at 132 °C ±5 °C and opens at 170 °C ±5 °C. Its 4 A, 120 VAC rating allows direct insertion in a drive-enable circuit. When used on 480 VAC supply systems, the motor’s insulation coordinates with the bus rating to maintain dielectric margins.
