Product Description:

The MSM100-6-604-M-0KA belongs to the MSM Brushless Servo Motors series from Kollmorgen. It is intended for axis control in packaging lines, pick-and-place modules, and other automated machinery that requires accurate position and speed regulation. As a brushless servo motor, it pairs with Kollmorgen drives to translate command currents into shaft torque, providing closed-loop motion without mechanical commutation. This arrangement supports responsive changes in velocity and position while avoiding the wear associated with brushes and mechanical commutators.

Rated for a nominal bus voltage of 460 V, the motor delivers continuous shaft torque of 0.72 Nm while sustaining a maximum speed of 6000 rpm. Momentary overloads can be handled up to 3.8 Nm, and the phase current may rise to 9.3 A peak during these transients. By contrast, standstill excitation draws only 2.0 A peak. A torque constant of 0.46 Nm/A indicates the proportional relationship between stator current and developed torque. The back electromotive force constant of 55 V/KRPM indicates the voltage returned to the drive as motor speed increases.

The rotor has an inertia of 0.00015 kg·m², allowing rapid acceleration without placing excessive demand on the drive. The internally wound coils have a self-inductance of 48 mH, which helps filter switching harmonics. Copper losses are governed by a winding resistance of 24.4 Ω, which also influences heat generation during continuous operation. The assembled frame weighs 4.9 kg, making it suitable for installation on smaller linear stages. A six-pole magnetic layout minimizes cogging, while the ST-60 steel shaft accepts couplings without additional hardening. Mounting uses an M5 × 0.8 mm threaded hole cut to a depth of 12.5 mm, providing a fixed attachment point for axial retention screws.
