MT502A2-R1C1 by Kollmorgen

The Kollmorgen MT502A2-R1C1 is a core member of the M Goldline Servo Motors series and represents Kollmorgen’s dedication to high-performance, compact designs. As a precision-driven solution, this servo motor delivers a continuous torque (stall) at 40C of 1.29 N-m and achieves a peak torque of 3.23 N-m, ensuring ample power for demanding tasks. It operates within a rated speed range of 4500 – 6000 RPM and reaches a maximum operating speed of 6000 RPM, offering both versatility and dynamic response. With a rotor inertia of 0.0000465 kg-m2 and a lightweight construction of 2.5 kg (without brake), the MT502A2-R1C1 balances rapid acceleration with smooth motion control, making it ideal for space-constrained installations.

Technical capabilities of this motor showcase advanced electromechanical design. The back EMF (line-to-line) of 32.6 VRMS/kRPM optimizes voltage generation at high speeds, while the DC resistance at 25C of 7.77 ohms ensures efficient current flow. Continuous operation is supported by a continuous line current of 2.44 ARMS and a peak line current of 9.0 ARMS for short-duration demands. Its 8-pole architecture enhances torque density, and a torque sensitivity (stall) of 0.540 N-m per Amp RMS provides precise current-to-torque conversion. Additionally, the viscous damping rate of 0.114 N-m/kRPM refines dynamic stability and attenuates oscillations during high-speed transitions.

Operational features focus on reliability, thermal management, and smooth control. With a thermal resistance at stall of 0.335 C/W, the motor effectively dissipates heat under overload conditions, reducing the risk of thermal shutdown. Low static friction of 0.030 N-m minimizes starting resistance, enabling immediate response to control inputs. The moderate rotor inertia ensures swift acceleration and deceleration, allowing rapid directional changes without undue latency. Together, these characteristics support consistent, repeatable performance in robotics, CNC machinery, and automation equipment.

Integration of the MT502A2-R1C1 into industrial systems is streamlined by its compact form factor and standardized mounting dimensions. Its compatibility with Kollmorgen drives and controllers simplifies system setup and parameter tuning for closed-loop operation. This motor’s robust specification set makes it well suited for applications in precision assembly, pick-and-place robotics, and semiconductor processing where tight speed regulation and high torque density are critical. By providing a balance of power, responsiveness, and thermal resilience, the MT502A2-R1C1 delivers a dependable solution for advanced industrial automation environments.
