Product Description:
The LSM100-46-454-S-0KA is a brushless servo motor produced by Kollmorgen and supplied within the LSM Brushless Servo Motors series. It translates three-phase AC power into precise shaft motion, allowing automated machinery to index, accelerate, and decelerate under drive control. The frame size and rotor construction support rapid response for packaging heads, electronic assembly gantries, and other axes that demand high duty cycles in compact spaces. Its brushless design eliminates mechanical commutation at the rotor, reducing wear during repeated speed changes. The motor operates with a compatible servo drive that regulates phase current according to commanded position, velocity, and torque.
At the motor shaft, a continuous torque of 5.2 Nm can be maintained at thermal equilibrium, and momentary load changes are managed by a peak current of 21.2 A. Rated speed reaches 4500 rpm, so high linear velocities can be achieved when the motor is paired with ball screws or belt stages. The windings are designed for a supply of 460 VAC, and each delivered ampere produces torque according to a constant of 0.88 Nm/A. Dynamic behavior is influenced by the rotor inertia of 0.00017 kg-m², which allows the drive to command rapid acceleration without overloading the control loops. Stall current reaches 6.4 A, while the back-EMF gradient is 106 V/kRPM. A winding resistance of 3.9 Ω and an inductance of 12.44 mH shape current ripple and affect servo bandwidth.
The motor can deliver a peak torque of 16 Nm for short intervals, providing extra force for indexing or overcoming static friction. Feedback is supplied by a single-turn sine-cosine encoder that returns absolute position within one revolution. No brake is fitted, so holding force must come from the drive or external mechanics when power is removed. The motor has a net mass of 6.3 kg, which supports manageable installation without adding excessive weight to the machine structure. The shaft end is tapped M5 × 0.8 mm to a depth of 12.5 mm for secure attachment to pulleys or couplings. This threaded feature can retain coupling hardware while the shaft transfers torque to the connected mechanism.
