Product Description:
The M.1015.8021 is a brushless servo motor manufactured by Kollmorgen within the HSM Brushless Servo Motors series. Intended for precision axes in automated assembly cells, the unit provides commanded torque and speed while embedded feedback maintains positional accuracy. A factory-mounted brake holds payloads during shutdown, so suspended loads do not require external clamping. By combining continuous-duty capability with controlled stopping, the motor supports high-cycle production where repeatable rotary motion is critical.
Its electromagnetic stack delivers a continuous torque of 50.8 Nm at the shaft, providing stable drive force through long duty cycles. When peak acceleration is required, the rotor can deliver a maximum torque of 124.3 Nm without exceeding thermal limits. The winding design supports speeds up to 2000 rpm, and the eight-pole layout keeps cogging low at low velocity. A voltage constant of 112 V/krpm pairs the motor with common 400 VAC-class drives, while the torque constant of 1.0 Nm/A simplifies proportional current scaling inside the controller. Torsional play is limited to 21 arcmin, so gear backlash does not dominate positioning accuracy. The phase resistance of 0.10 Ω minimizes resistive losses during fast reversals.
The spring-applied brake engages when power is removed and provides 50.8 Nm of static holding torque. It is released by a coil that draws 0.75 A DC from the control supply. Its armature is energized by 90 VDC, providing consistent clamping force across duty cycles. Including the brake, the assembly weighs 61.8 kg and measures 529 mm in length, allowing it to fit standard IEC mounting arrangements. Rotor inertia is 0.012 kg·m², supporting smooth stops without excessive overshoot. Thermal loading is managed through a housing thermal resistance of 0.21 °C/W. The laminated core has a phase inductance of 2.4 mH, which cushions current transients during rapid servo updates.
