Product Description:

The M.1015.8008 is a brushless servo motor engineered by Kollmorgen within the HSM Brushless Servo Motors series. Designed for precision drive axes, it delivers regulated rotary motion so that packaging lines, electronic assembly stations, and small machining centers can synchronize speed and position with their controllers. The motor operates in the 230 VAC voltage class, which must be supported by the connected servo drive.

The motor supplies a continuous output of 11.3 Nm, while its overload ceiling reaches 25.4 Nm for rapid acceleration events. A maximum mechanical speed of 3000 rpm lets the shaft execute fast indexing without exceeding the motor’s speed limit. The torque constant is 0.74 Nm/A, allowing the drive to determine the current required to produce a commanded torque. Current-loop tuning should account for the 4.4 mH phase inductance and 0.49 Ω winding resistance. The housing-to-ambient thermal resistance is 0.34 °C/W, so sufficient airflow or a conductive mounting surface is recommended to keep operating temperatures within acceptable limits. Total compliance is limited to 29 arcmin, helping maintain predictable positioning in backlash-sensitive gear trains.

An integral holding brake extends the motor body by 2.08 in and draws 1.13 A from a 24 VDC supply when energized. Once engaged, the brake can restrain static loads up to 300 lb-in. With the brake installed, the assembly weighs 22.5 kg, which should be considered when selecting mounting hardware or balancing a gantry axis. Dynamic response is supported by a rotor inertia of 0.0017 kg·m², reducing lag when command profiles reverse direction. At operating speed, the back electromotive force increases at 82 V/kRPM, allowing the drive to estimate velocity and establish suitable overvoltage protection thresholds.
