Product Description:
The LSM63-12-602-E1-2KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. It is designed to deliver precise torque and speed control for positioning axes, pick-and-place heads, and other automated mechanisms that depend on rapid acceleration and repeatable motion. By combining a permanent-magnet rotor with electronic commutation, the unit converts electrical energy into tightly regulated mechanical rotation for industrial automation tasks.
The motor operates from a nominal phase supply of 230 VAC and reaches a rated shaft speed of 6000 rpm, allowing direct coupling to high-speed machinery. Under continuous duty, it supplies 1.4 N·m of torque, while short bursts can reach 5.6 N·m for rapid indexing. The drive can draw up to 15.8 A Peak during dynamic moves, and at standstill the winding current is limited to 4.1 A Peak to prevent overheating. An internal 24 VDC fail-safe brake engages when power is removed, and an incremental encoder with 1000 lines enables closed-loop feedback to the motion controller. Eight magnetic poles generate the synchronous field, a milled keyway locks the shaft to the load, and 3.68 Ω of phase resistance affects power loss during continuous operation. Mechanical loading is supported by a 23 kg radial limit at 6000 rpm, which helps protect the bearings from excessive side forces.
The back-EMF constant is 43 V/kRPM, providing predictable voltage feedback to the servo amplifier for velocity estimation. A torque constant of 0.36 N·m/A links commanded current to output torque, while the phase inductance of 13.0 mH moderates current ripple and helps filter switching harmonics. These electrical values help the drive regulate acceleration, damp transient oscillations, and maintain accuracy across varying load conditions.
