Product Description:

The LSM23N-6-602-E1-2KA is a brushless servo motor manufactured by Kollmorgen within the LSM Brushless Servo Motors series. Designed for industrial automation, the device converts 230-volt AC supply power into controlled rotary motion for indexing tables, pick-and-place heads, and other precision axes. Integrated feedback and a low-inertia rotor allow the connected drive to command rapid speed transitions while maintaining the position accuracy needed in cycle-time-sensitive equipment.

Under continuous duty, the motor delivers 0.7 Nm of torque, allowing sustained load operation without overheating. With a rated input of 230 VAC and a back-EMF constant of 43 V/kRPM, the drive can predict generated voltage during dynamic deceleration. When fast cycles are required, the shaft can accelerate to 6000 RPM, and at that speed the current controller must handle up to 8.1 A peak. A stall current of 2.1 A peak limits static holding before thermal rise becomes critical. The motor produces incremental position feedback through a 1000-line encoder, enabling fine velocity loops in high-resolution applications. With a torque constant of 0.35 Nm/A, each ampere produces proportional torque, and the phase network uses a 26.2 mH inductance and 8.49 ohm resistance, which affect electrical time constants and copper losses.

The mechanical interface is a NEMA 23 square mounting face, allowing direct replacement of stepper motors in the same frame size. Momentary overload events are accommodated by a 2.8 Nm peak torque rating, giving the axis margin for acceleration spikes. The rotor's low mass of 0.000011 kg-m² minimizes the energy required to change speed, which helps shorten settling time. A keyway shaft transmits torque without slipping, and an optional fail-safe brake adds 42 mm to the overall length while engaging at 24 VDC to secure vertical loads when power is removed.
