Product Description:
The LSM100-35-454-M-2KA is a brushless servo motor manufactured by Kollmorgen within the LSM Brushless Servo Motors series. It delivers closed-loop rotary motion for packaging stations, assembly robots, and material-handling axes. A multi-turn absolute encoder provides position feedback even after power is removed, allowing the controller to resume operation without performing a homing cycle. The unit is designed for integration into servo drive systems that require high peak torque, moderate inertia, and reliable holding capability from an optional brake.
During continuous operation, the motor produces 4.0 Nm of torque while drawing a stall current of 5.0 A peak. This output represents the sustained mechanical load that the shaft can carry without overheating. The motor reaches a maximum speed of 4500 rpm, allowing the axis to move quickly between setpoints. Current demand rises to 22.6 A peak, and the magnetic circuit converts this current into torque with a constant of 0.86 Nm/A. Electrical response is influenced by a winding inductance of 16.8 mH, which affects current rise time and filtering requirements. A rotor inertia of 0.000174 kg·m² balances fast response with stable motion, while the 30 mm shaft and its 5 mm key transmit torque directly to compatible couplings.
Short-duration overloads are supported by a peak torque of 16.0 Nm, allowing the axis to overcome friction or accelerate payloads without excessive mechanical stress. At 3000 rpm, the bearings accept a radial load of 42 kg, allowing pulleys and gear sets to be mounted overhung without additional supports. The optional brake operates at 24 VDC and holds the shaft when motor power is removed, bringing the overall mass to 6.1 kg. The phase windings have a resistance of 5.9 Ω, while the voltage constant of 103 V per 1000 rpm indicates the generated back electromotive force and assists with drive sizing.
