Product Description:
The MSM115-89-404-S-2KA is a brushless servo motor manufactured by Kollmorgen for the MSM Brushless Servo Motors series. It serves as a rotary actuator in automated equipment, converting drive current into precisely controlled shaft motion for indexing tables, pick-and-place heads, and other positioning tasks. When integrated with a Kollmorgen servo amplifier, the motor delivers feedback-regulated torque so that machine cycles remain repeatable even under variable loads.
The actuator supplies a continuous stall torque of 10 Nm and can reach a peak torque of 32 Nm for short acceleration bursts without thermal overload. At its rated speed of 4000 rpm, the motor operates efficiently within a servo loop, allowing fast point-to-point moves. Motion commands at maximum output require up to 38.2 A peak, while static holding torque is maintained with a stall current of 10.9 A peak. Six permanent-magnet poles establish the electrical cycle frequency and contribute to smooth rotation with low cogging. The housing measures 317 mm from the mounting face, providing the magnetic stack depth needed to support the motor’s torque capacity. This compact profile accommodates installations where axial clearance is limited but substantial acceleration torque is required.
The torque constant is 1.03 Nm/A, indicating the amount of torque produced for each ampere of current. Back electromotive force develops at 123 V/KRPM, providing useful data for drive tuning and DC bus voltage selection. With the holding brake fitted, the rotor inertia is 0.00193 kg·m², supporting responsive and stable tuning on medium-load axes. The motor and brake assembly has a mass of 12.1 kg, making it suitable for gantry or robotic wrist installations with compatible structural support. A winding inductance of 12.0 mH and resistance of 2.0 Ω help limit ripple current and heat rise during continuous operation. Mechanical attachment uses an M6 × 1.0 mm shaft thread cut to a depth of 16 mm, allowing a compatible coupling or attachment to be secured to the output shaft.
