Product Description:

The MSM100-14-604-S-0KA is a brushless servo motor manufactured by Kollmorgen for the MSM Brushless Servo Motors series. This compact unit houses a six-pole permanent-magnet rotor and stator windings optimized for rapid response. It converts controlled current from a servo drive into precise rotary motion, providing the actuation needed in pick-and-place modules, electronic assembly stations, and light material-handling axes across industrial automation lines.

During continuous duty, the motor sustains 1.53 Nm of torque, enabling moderate loads to be moved without thermal derating. For short acceleration bursts, it delivers 8 Nm, so cycle times remain low. The rated output speed of 6000 rpm combines with its six-pole construction to balance velocity and resolution for servo control loops. A torque constant of 0.52 Nm/A links commanded phase current to mechanical torque, and the drive must be able to supply up to 17.7 A at peak demand. Electrical characteristics include a winding inductance of 22.0 mH and a resistance of 9.0 Ω, which affect current rise time and copper losses. Rotor inertia is 0.00021 kg·m², supporting rapid reversals while limiting load mismatch. The mechanical bearings are designed to carry radial forces at speed.

With a mass of 5.9 kg, the motor adds limited moving weight yet stores enough thermal energy for intermittent peaks. The ST-60 shaft can withstand a radial load of up to 34 kg at 6000 rpm, permitting direct belt or gear coupling. A metric M5 × 0.8 mm thread extends to a depth of 12.5 mm for secure hub mounting. Back EMF rises at 62 V/KRPM, so bus voltage selection must account for regenerative margins. To hold position without motion, the system applies 3.4 A of stall current, generating rated static torque without overloading the windings.
