Product Description:
The LSM100-46-454-M-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. This rotary unit converts electrical energy into controlled mechanical torque for positioning and velocity tasks in industrial automation. Integrated multi-turn feedback returns the absolute shaft position across multiple revolutions to drive controllers, allowing repeatable motion profiles without homing. The motor’s eight-pole design works with synchronous drive electronics to provide smooth torque delivery for packaging equipment, material-handling axes, and general-purpose machinery.
During continuous operation, the motor can sustain 5.2 Nm of torque without exceeding thermal limits, and this output is available up to the rated shaft speed of 4500 rpm. Electrical efficiency is supported by a torque constant of 0.88 Nm/A, meaning each ampere of phase current produces nearly one newton-meter of torque. The power stage must supply up to 21.2 A peak on demand, while the stator is wound for a nominal voltage of 460 V, matching common three-phase industrial power systems. These electrical characteristics help the drive regulate current accurately during continuous motion and changing load conditions.
Transient demands are covered by a peak capability of 16 Nm, allowing short bursts for acceleration or overcoming static friction. The rotor’s low inertia of 0.00017 kg·m² enables rapid speed changes with minimal overshoot when paired with a high-bandwidth drive. Mechanical integration is simplified by the motor’s 6.3 kg mass and an output shaft tapped with an M5 × 0.8 mm thread for drawbar-style couplings. From an electrical perspective, a winding inductance of 12.44 mH filters current ripple, improving servo stiffness while limiting high-frequency losses during pulse-width modulation. The threaded shaft connection can secure compatible couplings against axial movement, while the relatively low motor mass reduces the structural load placed on the mounting surface.
