Product Description:

Kollmorgen produces the LSM23N-6-602-E1-OKA brushless servo motor within the LSM Brushless Servo Motors series. The unit is designed to supply constant torque and precise feedback to indexing tables, pick-and-place arms, and other automated stages. Its compact form factor eases machine integration where rapid response and accurate positioning are required. This layout suits motion axes that cycle frequently and need consistent servo response without taking up much machine space.

The motor delivers a continuous torque of 6 in-lb, giving steady output during continuous operation. Its windings are optimized for 230 VAC operation, allowing connection to standard servo drives used in common factory power systems. The square front flange follows the NEMA 23 pattern, so it mates with widely available gearheads, brackets, and mounting plates. Internally, the stator is arranged for 3-phase excitation, which helps smooth electromagnetic torque and reduce ripple during speed changes. Position information is generated by an incremental encoder that outputs 1000 lines per revolution, providing 4000 quadrature counts to the controller for fine velocity and position loops.

The bearing system has a calculated life of 20,000 h L10, meaning 90 percent of units are expected to meet that duration under rated conditions. During operation, the housing may reach 125 °C, so nearby components and cable routing should account for the surface temperature. The shaft uses a keyway for positive torque transfer to pulleys or couplings without relying only on clamping friction. Encoder and Hall signals exit through a feedback connector with 17 pins, which simplifies signal routing while keeping power leads separate. Separate signal and power paths help maintain stable feedback in compact motion systems with repeated acceleration and deceleration.
