Product Description:
The LSM23N-6-602-E1-0KA belongs to the LSM Brushless Servo Motors series produced by Kollmorgen. It is a compact brushless servo motor built on a NEMA 23 mounting face and is intended for position and velocity control in automated machinery. The motor is supplied without a mechanical brake, so an external mechanism must hold the load whenever power is removed. A keyed shaft transmits torque directly to couplings or pulleys, providing positive engagement for applications with frequent acceleration and deceleration.
During continuous operation, the rotor can supply 0.7 N·m of torque, and the electromagnetic design supports speed regulation up to 6000 rpm for fast cyclic movements. The drive must accept a 230 VAC source and deliver the required phase current to the motor. Torque production is characterized by a constant of 0.35 N·m/A, meaning each ampere of sinusoidal phase current produces approximately one-third of a newton-meter of shaft torque. Dynamic response is influenced by the winding impedance. A phase-to-phase inductance of 26.2 mH moderates the current rise and helps smooth switching harmonics, while the 8.49 Ω resistance at 25 °C limits current under stall conditions. These electrical values allow a compatible servo drive to regulate torque while accounting for winding losses and current response.
For short bursts, the motor delivers a peak torque of 2.8 N·m, allowing it to accelerate small inertial loads such as indexing tables or pick-and-place arms. Position reporting comes from an incremental encoder with 1000 lines, providing 4000 quadrature counts per revolution for fine positional resolution. Drive sizing uses a back-EMF constant of 43 V/kRPM, which indicates the voltage generated per thousand revolutions and helps establish the required voltage margin at higher speeds. The moving assembly has a rotor inertia of 1.1 × 10⁻⁵ kg·m², enabling rapid directional changes without adding excessive mechanical resistance. The motor has a mass of 1.4 kg, which reduces the load placed on moving machine structures and mounting surfaces.
