Product Description:
The M.1015.7889 brushless servo motor is produced by Kollmorgen as part of the FSM Brushless Servo Motors series. Designed for fixed-frame industrial machinery, the motor operates with a 230 V-class three-phase servo drive that regulates the electrical power supplied to its windings. Motor feedback allows the connected drive to maintain precise torque, speed, and position control for conveyors, gantry axes, and material-forming equipment. An integrated spring-applied holding brake secures the connected load whenever power to the brake is removed, making the motor suitable for axes that must remain stationary during shutdowns.
The brake circuit draws 0.48 A DC at 90 V DC and locks the shaft with a static torque of 31.1 Nm. During continuous rotation, the electromagnetic stack sustains 20.8 Nm, while the rotor can operate at speeds up to 3000 rpm without derating. The overall length, including the brake, is 390 mm, allowing the unit to fit mid-sized gearboxes while leaving adequate room for cable routing. A thermal resistance of 0.37 °C/W supports heat-transfer calculations for operation under rated load. The winding has an inductance of 1.7 mH and a resistance of 0.26 Ω, providing the electrical characteristics required for responsive current regulation by the connected drive. The shaft end has an M8 × 1.25 thread that is 20 mm deep and accepts compatible puller hardware during coupling removal or service.
For short-duty bursts, the motor produces a peak torque of 42.4 Nm, providing additional force for rapid acceleration or temporary load changes. The brake-equipped rotor has an inertia of 0.011 kg·m², which must be considered when tuning acceleration, deceleration, and position-loop response. The motor weighs 35.4 kg, so its mounting surface and lifting arrangement must support the unit securely during installation and operation. A sine-referenced torque constant of 0.70 Nm/A relates commanded phase current to motor torque, while a back-EMF slope of 85 V/kRPM supports drive scaling and regenerative-voltage calculations. These electrical values also help determine suitable current limits and conductor capacity for the intended motion profile.
