Product Description:
The LSM100-46-454-S-2KA is a brushless servo motor built by Kollmorgen. It belongs to the LSM Brushless Servo Motors series. As a rotary actuator, it converts electrical energy from a matched drive into controlled torsional motion. The motor is designed for industrial automation axes that require precise velocity, torque, and position control.
In continuous duty, the motor can deliver 5.2 Nm of torque, a level intended for loads that draw steady mechanical power without overheating the stator. When short bursts are acceptable, the electromagnetic stack supports a peak torque of 16 Nm, giving machines reserve force for acceleration or disturbance rejection. Thermal rise is linked to current, so the specified stall current of 6.4 A(pk) represents the maximum winding current that may be applied continuously at standstill. For brief moves, the drive may supply up to 21.2 A(pk); this higher current produces transient torque but must be time-limited to keep the motor within its thermal limits. The rotor can reach 4500 rpm, permitting direct coupling to high-speed feed screws or belt stages while staying below centrifugal stress thresholds.
The electrical interface uses three-phase power at 460 VAC, matching the supply class used in American control cabinets. Inside the stator, a pole count of 8 sets the electrical cycle frequency and contributes to smooth torque production at low speeds. The back electromotive force has a voltage constant of 106 V/kRPM, which the drive uses to predict commutation voltage and set current loops. When equipped with the holding brake, the assembly weighs 7.1 kg, an important consideration when mounting the motor on moving carriages or lightweight gantries. The brake coil operates from 24 VDC. Accessory pulleys attach through an M5 × 0.8 shaft thread cut to a depth of 12.5 mm. A torque constant of 0.88 Nm/A links commanded phase current to output torque for current-mode drives. The motor has a rotor inertia of 0.0002 kg·m², a winding inductance of 12.44 mH, and a resistance of 3.9 Ω for servo tuning and drive sizing.
