Product Description:
The B-102-A-94-B9-025 is a permanent-magnet AC servo motor built by Kollmorgen and supplied within the Kollmorgen Goldline B and BH Motors series. The unit serves as a rotary actuator in industrial automation, where, when paired with a matched drive, it produces repeatable motion for indexing tables, pick-and-place axes, and metering pumps. Its compact frame and metric mounting pattern allow straightforward integration into machine frames.
Under continuous load, the motor draws 2.4 Arms and develops 0.84 N-m of stall torque, indicating the steady current and holding torque that can be maintained without thermal saturation. When driven up to its nominal speed of 7500 RPM, the shaft can deliver smooth power suited to high-speed positioning tasks. The coil generates 20.9 VRMS/kRPM of back electromotive force, a value the drive uses to regulate field-oriented control and guard against overvoltage conditions. The three-phase winding presents 30.0 mH of inductance, working with a direct-current resistance of 6.80 ohms to shape current rise time and copper losses. Four internal poles create the required synchronous field, and the standard metric mount simplifies alignment with gearheads or direct-drive couplings.
For short acceleration bursts, the amplifier may supply 7.2 Arms, allowing the rotor to reach a peak output of 2.41 N-m without demagnetization. Thermal modeling is based on a continuous rating of 0.54 kW and a housing-to-ambient thermal resistance of 1.30 C/W, so enclosure airflow or heatsinking can be sized to keep winding temperatures within insulation limits. The design accepts up to 250 VRMS line voltage, matching standard mid-bus servo drives. Position feedback is provided by a frameless resolver, giving angle information while tolerating electrical noise. There is no front shaft seal and no rear shaft extension, reducing drag and axial length for compact machines.
