Product Description:
The MSM215-407-304-M-0KA is a brushless servo motor manufactured by Kollmorgen within the MSM Brushless Servo Motors series. Designed for closed-loop axis control in industrial automation, the unit converts electrical energy into precise rotary motion that positions gantries, conveyors, or packaging spindles. An internal multi-turn, high-resolution feedback device supplies position data to the drive. The shaft is delivered without a holding brake, so an external mechanism must secure the load when power is removed.
Its continuous torque is rated at 46 Nm, establishing the torque available during steady motion cycles. When short bursts of acceleration are required, the motor can reach a peak torque of 128 Nm while drawing up to 117.4 A from the drive. Speed regulation centers on a nominal shaft velocity of 3000 rpm, supported by a six-pole rotor. The stator is designed for a line-to-line voltage of 460 V and operates with a compatible servo drive. Rotor inertia is limited to 0.0141 kg·m², which shortens acceleration times and improves following accuracy in indexing applications. The motor has a continuous stall current of 36.6 A, which must be considered during static holding duty.
The electromagnetic circuit has a phase inductance of 8.2 mH, which filters current ripple and works with the drive’s pulse-width modulation frequency to keep heating manageable. Copper losses are influenced by a winding resistance of 0.28 Ω measured at 25 °C, allowing the expected power dissipation to be calculated for operating loads. A torque constant of 1.40 Nm/A links commanded current to delivered torque and supports accurate controller gain settings. The back electromotive force constant is 170 V per 1,000 rpm, indicating how the generated voltage rises with motor speed. During rapid deceleration, regenerated energy must be managed by the connected drive, while vertical loads require suitable mechanical restraint when the system is not energized.
