Product Description:
The LSM100-22-454-S-2KA is a brushless servo motor manufactured by Kollmorgen within the LSM Brushless Servo Motors series. The compact unit is intended for closed-loop industrial automation where precise velocity and torque regulation are needed to drive small conveyors, index rotary tooling, or position gantry joints. By combining permanent-magnet excitation with stator windings matched to a separate drive, it delivers repeatable motion profiles while occupying minimal installation space.
Under continuous operation, the motor produces 2.5 Nm of torque while drawing a peak stall current of 3.3 A, a pairing that establishes the steady thermal load on the drive. During rapid acceleration, it can reach a transient torque output of 11 Nm when the controller supplies up to 16.3 A peak. The rated output speed is 4500 rpm, so a gearbox or belt stage can be sized around that operating limit. The motor has a three-phase electrical connection rated at 460 VAC, making it suitable for compatible industrial servo drives. An eight-pole rotor works with a single-turn, high-resolution feedback device to provide accurate commutation and position reporting. A 24 VDC holding brake keeps the connected load stationary when motor power is removed.
Magnetic and thermal behavior are characterized by a torque constant of 0.82 Nm/A, meaning each ampere of phase current generates approximately 0.82 newton-meter of torque at the shaft. The back-EMF slope is 99 V/kRPM, a value the drive monitors when managing voltage and field-weakening limits. Copper and iron dynamics are further described by a winding inductance of 25.8 mH and a winding resistance of 10.7 ohms, which influence current-loop bandwidth and heat rise. A rotor inertia of 0.000149 kg·m² supports quick reversals and responsive acceleration during short positioning cycles. The shaft has an M5 × 0.8 mm thread cut to a depth of 12.5 mm, providing a straightforward attachment point for compatible couplings or pulleys.
