Product Description:

The LSM130-102-304-M-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. It is used in industrial automation wherever precise speed and position control are required for packaging stations, pick-and-place axes, or coordinated multi-axis machines. By combining a low-cogging stator with a brushless rotor, the unit converts drive amplifier commands into accurate rotary motion for loads coupled through its keyed shaft.

This motor delivers a continuous torque of 11.5 Nm at its rated shaft speed of 3000 rpm, allowing steady operation without thermal derating. For rapid indexing or acceleration events, it can reach a peak torque of 52 Nm when the drive supplies up to 48.1 A Peak. The winding set is designed for the 460 V class, so the drive can achieve these levels without excessive bus current. An integral multi-turn high-resolution feedback device reports absolute position for closed-loop control, while the motor is supplied without a brake, so holding torque must be provided externally if the axis must remain locked when power is removed. Mechanical connection is handled by a keyway on the shaft, and mounting hardware engages an M8 × 1.25 mm internal thread with 19 mm of usable depth.

Dynamic response is influenced by the rotor inertia of 0.00055 kg-m², enabling fast speed changes without demanding high drive gains. At stall, the motor can draw 9.6 A Peak, producing torque in direct proportion to its constant of 1.28 Nm/A. Electrical time behavior is governed by a phase inductance of 12.4 mH, while copper loss is set by a winding resistance of 2.2 Ω. Back EMF generated during rotation follows a voltage constant of 154 V/kRPM, allowing the controller to predict motor voltage under varying load conditions.
