Product Description:
The LSM215-589-204-E2-2KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. It functions as a rotary actuator for positioning and velocity control in industrial automation cells, delivering commanded motion to gearboxes, belt drives, or directly coupled loads. In this role, it receives three-phase AC power from a matched drive and returns encoder feedback for tight servo loops.
In continuous operation, the motor provides 66 Nm of torque at its rated operating temperature, while short bursts can reach 210 Nm for acceleration or shock loads. These mechanical outputs are supported by a stall current of 38.9 A peak, and the drive can command up to 144.2 A peak during transient events before the motor reaches magnetic saturation. With a torque constant of 1.84 Nm/A, each additional ampere of phase current yields nearly two newton-meters of torque, simplifying current-based control strategies. This transient capacity allows the motor to accelerate demanding loads while maintaining steady torque during continuous operation.
The back electromotive-force constant is 222 V/kRPM, so at the maximum speed of 2,000 rpm, the motor generates approximately 444 V line to line, matching the 460 VAC supply rating used by many Kollmorgen drives. Phase impedance is shaped by a winding inductance of 7.4 mH and a resistance of 0.31 ohm, which influence current ripple and thermal rise. A 24 VDC spring-applied brake holds the motor in position during a power loss. The incremental encoder provides 2,000 lines of quadrature feedback to the servo loop, allowing the drive to monitor shaft movement accurately. The rotor has an inertia of 0.00856 kg-m², while the motor has an overall mass of 48.7 kg. An M12 × 1.75 mm shaft thread supports secure coupling to medium-inertia loads without additional flywheels.
