Product Description:

The B-102-A-32 is a brushless servo motor produced by Kollmorgen and supplied within the Kollmorgen Goldline B and BH Motors series. It is engineered to convert electrical energy from a matched drive into controlled rotary motion for positioning or velocity loops in automated equipment such as pick-and-place heads, web handling rollers, and indexing tables. Its brushless construction supports smooth response in repetitive motion applications.

This motor draws a continuous phase current of 2.4 Arms, indicating the steady-state current required to hold rated torque without overheating. Its phase-to-phase inductance measures 30 mH, which affects the electrical time constant, current rise, and drive tuning. The windings can be supplied from bus potentials up to 250 VRMS, which sets the insulation limit and helps identify compatible servo amplifiers. For rapid accelerations, the stator can accept a peak phase current of 7.2 Arms, allowing short bursts of three times the continuous rating. With that overload, the electromagnetic design yields a peak shaft torque of 2.41 N·m, supporting fast cycle moves before thermal averaging becomes critical.

The rated mechanical output is 0.54 kW, produced at a nominal speed of 7500 RPM. These values describe the continuous power capability when the motor is mounted to a heat-sinking surface. A rotor inertia of 0.000031 kg·m² supports quick response while minimizing overshoot in servo loops. Overall weight is 2.5 kg, which helps keep reflected mass low on moving axes. Additional characteristics include a torque constant of 0.35 N·m/Arms for straightforward current-to-torque conversion, a stall torque of 0.84 N·m at 40 °C for static holding tasks, and 0.04 N·m of static friction that must be overcome at start-up. Electrical resistance between phases is 6.8 Ω, and the back electromotive force is rated at 20.9 VRMS per kRPM, both of which are important for drive selection. Mechanical integration is simplified by a standard metric flange with no rear shaft extension, and quick wiring is provided by a bayonet connector that ships with mating plugs.
