Product Description:
The M.1015.7860 is a brushless servo motor manufactured by Kollmorgen for the FSM Brushless Servo Motors series. In automated machinery, it converts drive current into precisely regulated rotary motion, allowing axes to accelerate, decelerate, and hold position under closed-loop control. The unit is sized for medium-duty work cells where consistent torque and feedback fidelity are required for packaging lines, pick-and-place modules, or light machining centers.
Under continuous load, the motor delivers 3.5 Nm, while momentary overloads can reach 11.3 Nm without saturation. A torque constant of 0.54 Nm/A links commanded current to shaft output, and the back-EMF slope is 66 V/kRPM, values the drive uses to calculate voltage margins at the nominal 230 VAC stator supply. Electrical dynamics are shaped by a stator inductance of 6.8 mH; together with the 2.24 Ω winding resistance, it limits ripple current and controls thermal rise. Position data come from an optical encoder that produces 2,000 quadrature pulses per revolution, giving 8,000 counts after quadrature decoding for high-resolution servo loops. A 15.9 mm shaft interfaces with gearboxes or couplings, and the 114.3 mm pilot centers the frame on a mounting face.
Holding functions are provided by a permanent-magnet brake rated at 10.2 Nm; it is released by 0.26 A DC through a coil energized at 90 VDC. With the brake installed, the overall length is 257 mm, so cabinet depth and wiring allowances can be planned accurately. Dynamic response benefits from a rotor inertia of 0.0011 kg·m², enabling rapid start-stop cycles without excessive drive current. Heat flows from the windings to the housing at 0.63 °C/W, and the continuous thermal limit helps preserve insulation life when the motor operates near its rated capability.
