Product Description:

The M.1015.7998 is a Kollmorgen motor in the HSM Brushless Servo Motors series, intended for positioning or velocity-controlled axes in automated machinery. Inside a servo loop, it converts drive current into rotational motion that can be commanded with high precision. This capability allows conveyors, pick-and-place heads, or indexing tables to reach repeatable setpoints without mechanical gearing.

The rotor can reach a maximum speed of 4000 rpm, so motion profiles that demand rapid acceleration stay within electrical limits. A sine torque constant of 0.50 Nm/A indicates how much shaft torque the drive can expect for every ampere of phase current, while the voltage constant of 60 V/krpm indicates the back electromotive force that the inverter must overcome at high speed. Dynamic response is supported by a rotor inertia of 0.00054 kg·m²; this moderate value lets the axis change velocity quickly without excessive current spikes. Magnetic loading is governed by a winding inductance of 3.3 mH and a winding resistance of 0.69 Ω, two parameters that influence current ripple and thermal dissipation. During continuous operation, passive losses also result from a damping torque of 0.045 Nm/krpm and Coulomb friction of 0.068 Nm. The laminated stack has a length of 317 mm, and the assembled motor weighs 11.8 kg, which should be considered when sizing mechanical supports.

An integral brake supplies 10.2 Nm of holding torque. The brake is energized by 24 V DC, and its coil draws 0.69 A DC. Backlash in the brake coupling is limited to 44 arcmin for repeatable positioning at standstill. Heat generated by copper and iron losses exits the frame through a thermal resistance of 0.57 °C/W, so enclosure airflow or heat sinking must keep the winding temperature within allowable limits. The electrical insulation withstands 1,500 V AC RMS to ground for one minute, providing insulation protection when the motor operates with high-power servo drives.
