Product Description:
The M.1015.7878 brushless servo motor is manufactured by Kollmorgen as part of the FSM Brushless Servo Motors series. Built for industrial automation, the unit delivers commanded torque and velocity to indexing stations, gantry axes, and other precision loads where repeatable positioning is essential. A torque constant of 0.73 Nm/A links commanded phase current to produced torque, allowing the connected drive to regulate its current loop accurately.
The motor can deliver continuous shaft torque of 9.3 Nm while remaining within its thermal operating limits. For short acceleration bursts, it reaches a peak torque of 19.2 Nm, providing the capacity required to overcome brief inertial or friction loads. Its maximum mechanical speed is 3000 rpm, so transmission ratios must keep the reflected velocity below that limit. Electrical losses are influenced by a phase winding resistance of 0.98 ohm, which affects copper heat rise at a given RMS current and must be considered in thermal calculations.
An internal brake supplies 10.2 Nm of holding torque at standstill, preventing vertical or suspended axes from drifting when motor power is removed. The brake releases when its coil receives 90 VDC and draws 0.20 A, while backlash is limited to 44 arcmin for repeatable clamping. Rotor inertia is 0.0033 kg·m², allowing responsive velocity changes without placing excessive demand on the control loop. The winding inductance of 3.4 mH supports stable current regulation, while a voltage constant of 89 V/kRPM indicates the back EMF that the drive must overcome near maximum speed. The motor is rated for 230 V bus operation, with stator insulation and conductor spacing suited to common mid-power servo drives. An optical encoder supplies 2,000 lines of feedback from a 5 V source, providing the drive with position and velocity information. The assembly transfers heat through a thermal path rated at 0.40 °C/W.
