Product Description:
The MSM115-89-402-E2-0KA is a brushless servo motor produced by Kollmorgen within the MSM Brushless Servo Motors series. Designed for motion axes that demand compact torque generation and quick positioning, this motor converts drive current into continuous rotary power for industrial automation equipment such as gantries, feeders, and small conveyors. In these installations, the unit works with Kollmorgen servo drives to provide closed-loop velocity and position control so machine sequences stay synchronized with process commands.
The rated speed is 4000 rpm, allowing the rotor to complete rapid cycles while remaining within standard servo drive frequency limits. Rotor position is measured by an incremental encoder that produces 2000 lines per revolution; this resolution supplies precise feedback for tight loop gains without excessive data traffic. The encoder electronics are powered by a regulated 5 VDC source provided by the drive. When correctly aligned, the front bearing accepts a radial load of 48 kg at 4000 rpm, allowing pulleys or couplings to be mounted without causing premature bearing wear. Continuous operation is permitted at ambient temperatures from 0 °C to 40 °C and at relative humidity levels up to 95%, provided condensation is avoided. The permitted storage temperature ranges from -30 °C to 70 °C, helping protect the winding insulation while the motor is not in operation.
The output shaft has a keyway profile, providing positive torque transmission to hub components. A central tapped section with an M6 × 1.0 mm thread and a usable depth of 16 mm accommodates puller tools or locking screws during assembly. Stator and rotor losses can raise the external housing temperature to 125 °C, so adjacent wiring and sensors must be suitable for the expected heat. Because the motor is supplied without a brake, holding torque when power is removed must come from the drive or an external mechanical lock. The absence of brake hardware reduces axial length and rotor inertia, helping the servo accelerate rapidly within compact machine frames.
