Product Description:
Kollmorgen’s M.1015.8018 belongs to the HSM Brushless Servo Motors series and serves as a torque-controlled prime mover for precision machinery. In an automation line, it connects directly to a digital drive, allowing fast current loops to command shaft position or velocity without mechanical backlash. The frame integrates a fail-safe brake and resolver interface within an overall length of 478 mm, allowing the assembly to fit into confined machine spaces while supporting demanding operating cycles.
The motor supplies a continuous output of 39.5 Nm, giving actuators enough steady torque to hold or move loads without thermal derating. When speed commands peak, the rotor can reach 2000 rpm, a ceiling governed by magnetic flux density and bearing limits. Electromagnetic coupling efficiency is represented by a sine-wave torque constant of 0.86 Nm/A; this value allows the required current to be calculated for a given load profile. The stator windings are designed for a bus voltage of 230 V, matching common servo inverters and reducing the need for additional power conversion equipment. The copper paths have a resistance of only 0.13 ohm, which lowers resistive losses and helps control the housing temperature at the rated current.
A power-off holding brake secures the shaft with 50.8 Nm of static torque, preventing vertical axes from drifting when control power is removed. Transient movements, such as indexing or press strokes, can use a peak torque of 70.1 Nm for short periods without exceeding the motor’s magnetic limits. Dynamic response is supported by a rotor inertia of 0.0093 kg·m², balancing acceleration capability against load matching for stable servo tuning. Heat produced in the windings is transferred to the surrounding air through a composite frame with a thermal resistance of 0.23 °C/W. The motor has a mass of 50.9 kg, which must be considered when sizing mounting surfaces and support structures. Its thermal path helps the motor sustain operation while keeping winding temperatures within the insulation class limits.
