Product Description:
Kollmorgen’s M.1015.7993 is a brushless servo motor supplied under the HSM Brushless Servo Motors series. The unit provides programmable positioning and velocity control for indexing tables, pick-and-place heads, and other precision axes in automated production lines. An integrated 2000-line incremental encoder returns precise position data to the motion controller for closed-loop operation. A built-in holding brake securely maintains the shaft position when motor power is removed, making the motor suitable for axes that must remain stationary during shutdowns or pauses.
Under continuous load, the motor delivers 3.4 Nm of shaft torque while drawing power from a matched drive with a 230 V supply. Its output can rise to a peak torque of 11.3 Nm for rapid acceleration, and the rotor remains mechanically stable at speeds up to 4000 rpm. The electromagnetic system has a square-wave torque constant of 0.54 Nm/A, which indicates the torque produced for a given motor current. The winding resistance is 2.0 ohms, while the winding inductance is 9.0 mH; these values affect current demand and dynamic response during drive tuning. A voltage constant of 60 V/kRPM establishes the back EMF slope as rotational speed increases. The thermal resistance is 0.79 °C/W, indicating the relationship between generated heat and the resulting motor temperature rise.
The holding brake operates from a 24 VDC coil that draws 0.69 A DC when energized. Its friction plates lock the shaft with 10.2 Nm of static torque whenever the drive is disabled, helping prevent movement of a stationary load. The brake has a reflected inertia of 0.00033 kg·m², which contributes to the total rotational inertia seen by the drive. Maximum brake backlash is 44 arcminutes, an important consideration for applications requiring precise settling and load positioning after the brake releases. The complete motor assembly weighs 8.8 kg, which affects mounting support and the static load applied to the machine frame. Brake inertia, backlash, and assembly mass should be included when calculating acceleration, deceleration, and settling behavior for the connected axis.
