Product Description:
The LSM215-589-204-M-2KA is a brushless rotary servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. Designed for closed-loop positioning and velocity control, the unit converts electrical commands from a drive into precise mechanical torque for axes in packaging, material-handling, and machining equipment. Its brushless construction reduces maintenance, and the integrated feedback device returns absolute multi-turn position data to the controller, allowing accurate homing and repeatable motion sequences in demanding industrial automation applications.
During continuous operation, the motor supplies 66 Nm of torque, enabling stable operation with high-inertia loads without overheating. A nominal shaft speed of 2000 rpm pairs with the stator winding to accommodate common gear ratios, while the rated supply voltage of 460 VAC allows connection to standard industrial power systems through a regenerative servo drive. Peak phase current can reach 144.2 A, so the drive must provide adequate current foldback during acceleration. With a torque constant of 1.84 Nm/A, each ampere of phase current produces consistent torque for precise current-loop control. The holding brake operates at 24 VDC to secure vertical axes when motor power is removed. Eight rotor poles, 7.4 mH of inductance, and 0.31 Ω of resistance influence the electrical time constant, while the bearings tolerate a radial load of 112 kg at rated speed.
For rapid indexing, the motor can reach a momentary output of 210 Nm, providing reserve torque for startup friction or emergency stopping. Back electromotive force follows a constant of 222 V/kRPM, so the connected drive must accommodate this voltage during deceleration. A housing mass of 48.7 kg adds thermal capacity that moderates temperature rise, while a rotor inertia of 0.00856 kg·m² stabilizes acceleration profiles. Mechanical attachment uses an M12 × 1.75 mm shaft thread, allowing secure coupling to gearboxes or pulleys. The threaded interface helps prevent axial movement when the motor transfers torque to the connected machine assembly.
