Product Description:
The M-605-B- B1-B3 is a brushless AC servo motor built by Kollmorgen within the M Goldline Servo Motors series. Designed for closed-loop motion platforms, the unit converts commanded current into proportional torque for axes that require precise positioning and stable speed regulation. In industrial automation, it can couple directly to gearheads, ball screws, or timing pulleys to drive packaging lines, pick-and-place gantries, and similar electromechanical stages. Its brushless design supports consistent rotary response during repetitive duty cycles. This layout is suited to machinery that needs repeatable starts, stops, and speed changes throughout regular production use.
Continuous output characteristics describe how the motor operates under steady thermal conditions at 40 °C. It can deliver a sustained torque of 30.1 N·m while drawing 27.7 A RMS from the drive, allowing continuous load handling without overheating. With a rated mechanical power of 7.7 kW at a nominal shaft speed of 3150 rpm, it suits medium-frame amplifiers that operate on line supplies up to 250 V RMS. A torque constant of 1.09 N·m/A RMS links commanded phase current to produced torque, while a back electromotive force of 65.9 VRMS/kRPM supports drive voltage selection. Inductance of 6.3 mH and a DC resistance of 0.234 Ω affect current ripple and copper losses, and the six-pole rotor works with the stator windings to produce synchronous flux.
Dynamic limits support short acceleration bursts. The motor can withstand a peak torque of 87.7 N·m for brief intervals when the controller supplies up to 84.8 A RMS. These short-term limits are intended for transient demand rather than continuous operation. A rotor inertia of 0.01406 kg·m² balances rapid speed changes with load stability, which helps maintain tight servo loops. The housing has IP65 protection, and the motor also includes a 24 VDC fail-safe brake for applications that need holding force on vertical axes. Its mass of 28.7 kg supports stable mounting on machine structures.
