Product Description:
The M.1015.6963 is a brushless servo motor produced by Kollmorgen for the NSM Brushless Servo Motors series. As a permanent-magnet rotary actuator, it converts electrical energy into controlled torque for positioning and velocity loops in automated machinery, including pick-and-place axes and indexing tables. The motor integrates with Kollmorgen servo drives to close current and speed loops, providing accurate motion under dynamic load demands.
Its continuous shaft capability is rated at 3.8 Nm, which is the steady torque the stator can deliver without exceeding thermal limits. For short bursts, the electromagnetic design supports a peak torque of 10.7 Nm, enabling quick acceleration or disturbance rejection. The motor operates with a line-to-line voltage of 230 V supplied by a compatible servo amplifier. With a 5000-line incremental encoder fitted, the controllable speed is capped at 3600 rpm to keep the feedback frequency within the counter bandwidth. A torque constant of 0.38 Nm/A links commanded phase current to developed torque, simplifying current-mode tuning.
The mechanical rotor assembly has a reflected inertia of 0.00090 kg·m²; this moderate value lets the drive achieve rapid velocity changes without excessive current spikes. Electrically, each phase pair has an inductance of 4.3 mH and a resistance of 0.89 Ω. These electrical values affect current rise time and copper losses during continuous operation. Thermal performance is governed by a housing-to-ambient thermal resistance of 0.81 °C/W, allowing the stator to reject heat generated by copper losses. Supplementary values include a friction torque of 0.078 Nm, a voltage constant of 47 V/krpm, and a net weight of 9.1 kg, which help with the selection of suitable gear ratios, drives, mounting supports, and cooling provisions.
