Product Description:

The B-402-A-23 is an AC servo motor produced by Kollmorgen within the Goldline B and BH Motors series. In motion-control assemblies, the unit converts electrical input from matched drives into rotary torque for positioning tables, packaging spindles, and similar automation axes. This model is intended to supply moderate continuous torque with short-term overload capability for dynamic indexing and repeatable speed control. It can be paired with servo amplifiers that regulate torque, speed, and position in closed-loop automation systems. Its overall operating profile suits industrial machinery that needs stable servo response without an oversized motor frame.

The motor delivers a continuous mechanical output of 0.97 kW when it is supplied with 230 VAC, drawing 3.0 A RMS under rated conditions. This current level keeps thermal loading within the continuous operating range during sustained duty. A continuous stall torque of 6.8 N-m supports holding force at zero speed, and a back electromotive force constant of 136.0 VRMS/kRPM indicates the generated voltage in relation to shaft speed. That voltage constant affects how much drive bus headroom remains as speed increases. Rated and maximum operating speed are both 1500 RPM, so the shaft can run at full nameplate speed without a separate overspeed range. Bus capacitors inside the drive may be charged to 320 VDC, enabling a peak output torque of 19.8 N-m during acceleration and short indexing moves.

For brief transients, the controller may source 9.3 A RMS, which allows higher momentary torque during starts and rapid load changes. A phase inductance of 220 mH and a DC resistance of 10.5 ohms slow the rate of current rise and help smooth inverter output. That electrical combination also helps limit abrupt current changes in the windings. The four-pole rotor supports synchronous operation, and the motor develops 7.2 N-m of stall torque at 25 °C. Stable rotor synchronization supports controlled motion at low and moderate speeds. Line insulation is approved up to 250 VRMS, which is suitable for common industrial supply environments.
