Product Description:

The LSM100-46-454-E2-OKA is a brushless servo motor produced by Kollmorgen for the LSM Brushless Servo Motors series. As a permanent-magnet rotary actuator, it converts drive current into controlled mechanical rotation for automation axes that require precise positioning or continuous-duty motion. The motor uses an incremental encoder with 2000 lines, so motion controllers receive detailed position data for packaging, pick-and-place, and material-handling tasks.

Under continuous load, the motor delivers 5.2 Nm of torque while maintaining a shaft speed of 4500 rpm, giving machinery a stable operating range without overheating. Output rises in proportion to phase current because the torque constant is 0.88 Nm/A, which supports predictable current-loop response. The windings have an inductance of 12.44 mH, which helps limit current ripple during inverter switching. For short acceleration bursts, the rotor can withstand up to 16 Nm, enabling rapid indexing. The copper coils present 3.9 Ω of resistance, and a stall condition can be supported at 6.4 A peak when mechanical locks engage. The motor uses eight magnetic poles, and the 14 mm ST-60 steel shaft transmits torque directly to couplings.

A back-EMF constant of 106 V/kRPM indicates the DC bus voltage needed at high speed and the regeneration level during braking. Rotor inertia is 0.00017 kg·m², which keeps stored momentum low so axes can settle quickly after a move. The drive can command up to 21.2 A peak without exceeding the motor’s magnetic limits. Overall mass is 6.3 kg, which helps when the motor is mounted on moving slides or compact gantries. These values suit applications that need fast response, controlled acceleration, and stable servo performance across repeated motion cycles.
