Product Description:

The B-202-C-23 servo motor is produced by Kollmorgen within the Kollmorgen Goldline B and BH Motors series. It converts drive current into controlled rotation for axes such as indexing tables, pick-and-place heads, and feed rolls. The compact frame accepts direct coupling to gear sets or belts, supplying repeatable torque at high speed for general automation.

During steady operation, the winding carries a continuous phase current of 5.00 Arms, producing a rated mechanical output of 1.5 kW while the copper stays within its thermal limit. For short acceleration bursts, the drive may command up to 16.6 Arms, allowing rapid speed changes without demagnetizing the rotor. The motor reaches its nominal velocity of 6200 RPM, a figure that balances centrifugal stress with iron loss. A torque constant of 0.49 N-m/Arms links stator current to shaft torque, simplifying current-loop tuning. Electrical dynamics are influenced by the phase inductance of 25.0 mH and a DC resistance of 2.34 Ω. The generated back electromotive force is 29.4 VRMS per kRPM, and the stator laminations are contained in a body that is 123.9 mm long, which helps the motor fit compact machines.

The motor can deliver a peak shaft torque of 7.65 N-m for dynamic load steps that last a few hundred milliseconds. When the shaft is locked at 25 °C, it can sustain a stall torque of 2.59 N-m; this value decreases to 2.44 N-m at 40 °C as winding resistance rises. The motor connects to bus supplies up to 250 VRMS, which keeps insulation stress within safe limits. Rotor inertia is 0.0000996 kg·m², so the servo loop can achieve high bandwidth without excessive drive current. The assembled unit measures 236.2 mm overall and weighs 4.1 kg, making it straightforward to integrate on slide carriages or cantilevered brackets where low mass is important.
