Product Description:
The MSM215-319-304-S-0KA is a brushless servo motor manufactured by Kollmorgen within the MSM Brushless Servo Motors series. Designed for closed-loop motion axes in industrial automation, this unit converts electrical energy into precisely regulated mechanical torque and speed for positioning tasks on packaging lines, robotics, and conveyor stations. It uses a single-turn high-resolution feedback device for rotor position reporting, and its 6-pole rotor supports smooth electronic commutation during controlled motion. This arrangement helps the paired drive maintain accurate position and speed regulation through repeated starts, stops, and direction changes.
The motor delivers a continuous torque of 36 Nm at its rated operating point. At the rated speed of 3000 rpm, this torque provides steady mechanical output for mid-range loads. The 3-phase stator is energized from a 460 V supply, and dynamic demands are met with up to 93.3 A pk of phase current. Winding inductance is 10.6 mH, which affects current rise time and contributes to stable electromagnetic behavior. That combination lets the inverter regulate phase current predictably during speed changes and varying load conditions. The assembly weighs 33.0 kg, and the copper windings show 0.40 Ω resistance at 25 °C, which helps limit I²R losses. The voltage constant is 164 V/KRPM, which indicates the back-EMF level presented to the inverter during regeneration.
Transient performance is characterized by a peak torque of 100 Nm, giving short bursts of nearly three times the continuous rating for acceleration profiles. During locked-rotor testing, the drive can supply a stall current of 28.7 A pk, which indicates the thermal limit for steady static loads. The rotor inertia of 0.0108 kg-m² helps maintain speed stability under changing load, while the torque constant of 1.36 Nm/A supports responsive acceleration. The shaft is machined from ST-60 steel for fatigue resistance, and the laminated core construction helps keep magnetic losses low when the servo holds position. This motor is suited for point-to-point moves in indexing tables and articulated joints where rapid settling is required.
