Product Description:

The M.1015.6954 is a brushless servo motor produced by Kollmorgen within the NSM Brushless Servo Motors series. Designed for closed-loop positioning, it converts drive current into rotational motion that moves pick-and-place axes, indexing tables, and packaging feeders with repeatable accuracy. When integrated with a compatible servo amplifier and encoder, the unit supplies tightly regulated speed and torque that keep automated processes on cycle and within tolerance. It provides a direct electromechanical interface between control electronics and the mechanical load, making it a core element of compact machinery and laboratory automation cells.

Rated for 230 V, the coil set draws current that produces torque in proportion to the torque constant of 0.17 Nm/A. Under steady thermal conditions, the shaft can supply 0.8 Nm continuously, while short acceleration bursts reach 2.5 Nm to overcome load inertia. The maximum rotational velocity is 3600 rpm, permitting direct operation of moderate-speed mechanisms. Heat leaves the windings through a thermal resistance of 1.6 °C/W. Electrical behavior is influenced by an inductance of 6.1 mH and a resistance of 2.2 Ω, both of which affect the drive’s current-loop response. The bearings accept a radial load of 13.6 kg, supporting belt tension or moderate pulley overhang without reducing service life.

The back electromotive force constant is 21 V/krpm, indicating the voltage that the amplifier must overcome as speed increases. An incremental encoder with a resolution of 5000 lines per revolution feeds precise position data to the control loop, and static friction is limited to 0.021 Nm for smooth low-speed motion. A rotor inertia of 0.00008 kg·m² allows rapid speed changes while damping small load disturbances. The total assembly mass is 2.6 kg, easing installation on moving axes and minimizing structural load.
