Product Description:

The B-106-B-32-B3-098 is a brushless servo motor produced by Kollmorgen as part of the Goldline B and BH Motors series. Designed for closed-loop motion stages, pick-and-place modules, and packaging actuators, the motor delivers programmable rotation that matches commanded position and velocity profiles. In servo systems, continuous feedback allows the controller to correct speed and position errors as load conditions change. By integrating a permanent-magnet rotor with stator windings sized for medium power, it serves as the rotating actuator in automation cells that require precise speed control and quick transient torque.

At a winding temperature of 40 °C, the motor supplies a continuous torque of 2.22 N-m while drawing a steady phase current of 6.0 A RMS. During acceleration or shock loading, it can reach a peak torque of 6.35 N-m supported by a momentary phase current of 18.0 A RMS. Mechanical output stays stable up to the maximum rated speed of 7500 RPM, a limit set by the rotor design and bearing system. When the shaft spins at 1 kRPM, the windings generate 22.5 VRMS of back electromotive force, so the drive must compensate for this counter-voltage. With a line insulation rating of 250 V RMS and a continuous power capability of 1.5 kW, the motor can be coupled to mid-voltage amplifiers without derating.

The motor has a torque constant of 0.37 N-m/A RMS, an inductance of 9.4 mH, and a phase resistance of 1.60 Ohms; together these values set the current loop response needed for fast positioning. These electrical values also affect how quickly current can rise and how smoothly the axis responds to command changes. The rotor inertia of 0.0000765 kg-m² allows quick speed changes without excessive drive energy. A factory-mounted fail-safe brake engages at 24 VDC, draws 0.93 A, and supplies 2.3 N-m of holding torque to secure vertical loads when power is removed. Thermal resistance from winding to ambient is 0.89 °C/W, enabling the housing to dissipate heat generated during sustained duty cycles.
