Product Description:

The LSM215-589-204-S-0KA is a brushless rotary servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. As a permanent-magnet AC machine, it converts stator-supplied current into controlled shaft torque and speed for positioning tables, gantry axes, and other closed-loop automation tasks on the factory floor. The motor body measures 424 mm from the mounting face, placing it in the higher-power segment of the platform. Its design supports direct coupling to gear stages or belt drives during demanding duty cycles.

The motor can deliver a peak torque of 210 Nm, allowing rapid acceleration of sizable mechanical loads. To reach that output, the windings may draw a maximum peak current of 144.2 A, while continuous stall conditions are limited to 38.9 A peak to maintain thermal balance. Each ampere produces torque according to a torque constant of 1.84 Nm/A. The generated back electromotive force follows a slope of 222 V/kRPM, and these electrical parameters support matching inverter selection. The bearing design tolerates a radial load of 112 kg at 2000 rpm, allowing pulleys or pinions to be mounted overhung without auxiliary supports. Eight magnet poles establish the electrical frequency relationship between the drive electronics and rotor position.

A rotor inertia of 0.0077 kg·m² balances dynamic response and load stability, enabling smooth tuning when the axis is paired with compliant couplings. The laminated stator has a winding inductance of 7.4 mH and a phase resistance of 0.31 Ω, which servo amplifiers use to shape current loops and estimate thermal dissipation. The overall motor mass is 45.5 kg, which must be considered when selecting mounting structures and lifting equipment. A threaded shaft end is machined to M12 × 1.75 mm with a thread depth of 28 mm. This threaded interface simplifies the attachment of locking nuts or hub adapters and helps keep the connection rigid during changes in direction.
