Product Description:
The LSM130-78-454-S-2KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. It is intended for closed-loop speed and torque control in automated machinery, where precise rotary motion must be coordinated with drives and PLCs. As a frameless permanent-magnet unit equipped with an integrated fail-safe brake and encoder, it serves as a compact actuator for material-handling axes, packaging lines, and indexing tables. The brushless design reduces wear associated with mechanical commutation while supporting responsive operation during repetitive motion cycles.
The motor delivers a continuous shaft torque of 8.8 Nm without overheating when it is mounted to an adequate heat sink. The winding supports a maximum mechanical speed of 4500 rpm, allowing rapid cycle times while remaining below critical vibration limits. A torque constant of 0.88 Nm/A links commanded current to output torque, while the back electromotive force has a voltage constant of 107 V/krpm. Peak acceleration current reaches 50.9 A during brief commands. The copper windings and iron core provide a phase inductance of 8.46 mH, which affects current-loop bandwidth. The phase resistance is 1.68 Ω, and intermittent stall operation draws a peak current of 10.7 A. These electrical values help users select a compatible drive and evaluate heat generation under changing loads.
The motor provides a peak torque capability of 38 Nm for short periods of high acceleration or load demand. A holding brake powered by 24 VDC secures vertical or suspended loads when electrical power is lost. With the brake installed, the assembly weighs 11.2 kg, while its rotor inertia of 0.00049 kg·m² supports fast start-and-stop operation with moderate load matching. Eight poles work with single-turn sine-cosine feedback to provide smooth vector control and accurate rotor-position information. Mechanical attachment uses an M8 × 1.25 mm tapped shaft end with a usable depth of 19 mm, allowing direct coupling to gears or pulleys without additional adapters.
