M-605-A-B1-B2 by Kollmorgen

The M-605-A-B1-B2 servo motor from Kollmorgen embodies the advanced design principles of the M Goldline Servo Motors series, delivering an ideal combination of power density and precise control for heavy-duty industrial automation. This unit produces a rated horsepower of 8.6 HP (6.4 kW) at a Speed At Rated Power of 3150 RPM, matching its Max Operating Speed of 3150 RPM for seamless integration into high-speed machinery. It draws a Continuous Line Current (ic) of 27.7 Amps RMS under nominal load, with a peak demand of Peak Line Current (ip) at 84.8 Amps RMS to accommodate transient dynamic loads. With a Weight (without Brake) of 51 lb (23.1 kg), the motor balances mechanical robustness and ease of mounting. Its Dc Resistance (rm) of 0.234 Ohms and Inductance (lm) of 6.3 mH establish a stable electrical foundation for efficient thermal management and predictable current response.

Performance is characterized by a Continuous Torque (stall At 25°C) rating of 23.5 lb-ft (31.8 N-m) and a Continuous Torque (stall At 40°C) of 22.2 lb-ft (31.0 N-m), ensuring consistent stall torque across typical operating temperatures. For short-duration acceleration or deceleration tasks, the motor achieves a Peak Torque (tp) of 64.7 lb-ft (87.7 N-m), enabling rapid positioning and high-inertia load handling. The Rotor Inertia (jm) of 0.001500 lb-ft-sec² allows swift speed transitions while maintaining precise motion profiles. Thermal stability is enhanced by a Thermal Resistance (rth) of 0.28 °C/W, facilitating continuous operation without compromising performance. These electrical and mechanical parameters work in concert to deliver smooth torque curves, low torque ripple, and responsive dynamic behavior under variable loads.

Reliability is further supported by an integrated Electromagnetic Fail-safe Brake Torque of 35.0 lb-ft (48.0 N-m), providing secure holding in power-loss scenarios and simplifying system safety design. The motor’s rugged construction and adherence to Kollmorgen’s stringent quality standards ensure long service life in harsh environments. Installation is straightforward, with standardized mounting dimensions and connection interfaces that ease integration into CNC machine tools, robotic arms, and automated assembly lines. Applications span precision machining, packaging equipment, material handling, and other industrial automation systems requiring repeatable accuracy and high torque capacity. Backed by comprehensive technical support and a one-year warranty, the M-605-A-B1-B2 servo motor offers a dependable solution for demanding motion control challenges.
