Product Description:
The M.1015.7872 is a brushless servo motor produced by Kollmorgen within the FSM Brushless Servo Motors series. It is intended for positioning and velocity control in automated machinery. Closed-loop feedback allows a connected drive to regulate shaft motion to precise setpoints for conveyors, gantries, or rotary actuators.
This model delivers a continuous torque of 9.3 Nm, allowing it to maintain its rated load without thermal overload. When short bursts of additional force are needed, the shaft can sustain a peak torque of 19.2 Nm before drive current limiting occurs. The rotor can turn at up to 3000 rpm, a speed ceiling aligned with standard industrial gear ratios. Power is supplied by a drive section that outputs 230 V, so connected components must accommodate that voltage level. An internal holding brake clamps the shaft with 10.2 Nm of static torque, preventing back-driving on vertical axes when power is removed.
Dynamic response is influenced by a rotor inertia of 0.0033 kg·m², which balances quick acceleration with stable load coupling. Electromagnetic conversion efficiency is indicated by a sinusoidal torque constant of 0.73 Nm/A, translating drive current directly into usable shaft torque. Heat generated in the stator flows to the surrounding air through a thermal path rated at 0.40 °C/W, so airflow or mounting surfaces must limit the temperature rise predicted from duty calculations. The phase windings store energy with an inductance of 3.4 mH, affecting current ripple and drive-filter design. The motor also has a voltage constant of 89 V/kRPM for back-EMF estimation and a winding resistance of 0.98 Ω that contributes to copper losses. The brake coil draws 0.69 A DC, while the motor supports a radial load of 51 lb at full speed. Its overall length is 413 mm, and its mass is 21.4 kg.
