Product Description:
The M.1015.6967 is a brushless servo motor produced by Kollmorgen for the NSM Brushless Servo Motors series. This rotating actuator couples directly to gearboxes or load shafts and is intended for precise position and speed regulation in industrial automation cells. When paired with a compatible digital drive, the motor supplies feedback-controlled torque that supports coordinated motion sequences in packaging lines, material-handling axes, and light machining spindles. Its frameless permanent-magnet topology and integrated optical encoder allow the host controller to command rapid acceleration while requiring less maintenance than brushed designs.
In continuous operation, the motor produces a stall torque of 6.0 Nm, providing stable drive torque for index moves. For short bursts, it can deliver up to 17.0 Nm to overcome startup inertia or process shocks. A torque constant of 0.63 Nm/A relates phase current to mechanical output, while the back EMF constant is 77 V/kRPM; these values guide drive tuning and regeneration settings. Position feedback comes from an optical encoder with 5000 lines, and the sensor limits commutation speed to 3600 RPM. The bearings permit a combined axial load equal to 44% of the rated radial capacity, and the radial load limit at 500 rpm is 92 kg. Because the motor is supplied without a holding brake, external clamping is required when the shaft must remain locked while power is off.
The thermal and electrical characteristics support reliable operation at an ambient temperature of 40 °C. The windings are optimized for a 230 V bus, and their impedance is characterized by a phase inductance of 7.0 mH and a phase resistance of 1.23 Ω. These values influence current ripple and drive power-stage sizing. The laminated rotor has an inertia of 0.00147 kg·m², enabling quick acceleration without excessive overshoot when coupled with the available torque. The overall assembly mass is 13.0 kg, so the motor mounting brackets must support that static load. Proper mechanical support also helps prevent unwanted movement at the mounting interface during repeated acceleration and deceleration cycles.
