Product Description:

The M.1015.8020 is a brushless servo motor manufactured by Kollmorgen and supplied under the HSM Brushless Servo Motors series. Designed for precision positioning and velocity control, the unit combines high-density magnetic hardware with an integral brake and optical encoder to serve motion axes in industrial automation cells. Its intended role is to convert drive current from a servo amplifier into tightly regulated shaft torque and speed so gantries, presses, and material-handling equipment can follow programmed trajectories without mechanical play.

An integrated power-off brake secures the load when the drive is de-energized. It produces a holding torque of 50.8 Nm and draws only 2.00 A DC, making it suitable for vertical axes that must remain stationary during service or emergency stops. The brake coil requires a 24 V DC supply. Rotor inertia is limited to 0.012 kg·m², so the brake assembly does not compromise dynamic response when power returns. Including the brake assembly, the motor has a mass of 61.8 kg, which must be considered when selecting mounting hardware and lifting equipment.

The back-EMF constant is 112 V/krpm, which relates shaft speed to the voltage generated by the motor and affects regenerative energy levels. For torque calculations, the sine-wave torque constant is 0.92 Nm/A. The winding inductance of 2.4 mH affects current-loop bandwidth and filter selection. The motor uses an eight-pole magnetic circuit and can reach a continuous speed of 2000 rpm with appropriate drive settings. Its square-wave torque constant is 1.0 Nm/A, while its thermal resistance is 0.21 °C/W. The winding resistance is 0.10 Ω, and brake backlash is 21 arcmin. The 2000-line optical encoder operates from a 5 V DC supply and provides the position feedback required for closed-loop motion control.
