Product Description:
The B-204-V-99-270 belongs to the Kollmorgen Goldline B and BH Motors series and is manufactured by Kollmorgen. As a permanent-magnet AC servo motor, it is intended for closed-loop motion control tasks such as pick-and-place heads, packaging machinery axes, and coordinated gantry drives. In those applications the motor converts electrical energy into precise torque and speed under the supervision of a matching servo amplifier, providing rapid acceleration and repeatable positioning for automated equipment.
The motor has a stator outside diameter of 100 mm, which places it in a mid-range envelope that fits compact machine frames while still allowing adequate thermal mass. The windings are designed for a 230 VAC supply, so standard three-phase mains or regulated inverters can power the axis without step-up transformers. At the shaft, the motor can deliver 5.9 Nm of continuous torque, and its electromagnetic design supports a base speed of 3600 RPM for direct coupling to moderate-ratio gear stages or belt drives. The enclosure is rated IP54, which protects internal components against limited dust ingress and water spray and allows mounting on the machine frame without a separate cabinet.
Position feedback is provided by a resolver, giving analog sine-cosine signals that remain accurate at high temperatures and resist electrical noise. Torque density is increased by using a rotor built with Neodymium-Iron-Boron magnets, which produce strong flux while minimizing rotor inertia. The mounting interface follows a NEMA 34 pattern, so the motor can fit frame-matched steppers or brushed servos without drilling new holes. For thermal protection, a thermostat embedded in the windings opens at 170 °C ±5 °C and is rated for 4 A at 120 VAC, allowing the drive to disconnect power if abnormal heating occurs.
