Product Description:

The LSM215-589-204-E2-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. As a rotary actuator intended for industrial automation, it converts controlled electrical power into mechanical torque for positioning, conveying, or coordinated motion tasks that require tight velocity and torque regulation. A rotor inertia of 0.0077 kg·m² balances acceleration capability with load matching, while the keyway shaft facilitates coupling to pulleys or gearboxes.

This model delivers a continuous shaft output of 66 Nm while maintaining its rated speed of 2000 rpm, so it can hold process loads without overheating during steady operation. The stator windings are designed for a nominal line voltage of 460 VAC, which matches common three-phase plant power and keeps cabling currents moderate. For every ampere applied, the electromagnetic circuit produces 1.84 Nm/A; this torque constant simplifies drive sizing because commanded current translates predictably into load torque. Dynamic response is influenced by a phase-to-phase inductance of 7.4 mH, which limits current ripple and works with the 0.31 Ω winding resistance to shape the motor’s electrical time constant. Eight rotor poles interact with a 2000-line incremental feedback device, allowing the drive to resolve 8,000 counts per revolution after quadrature and provide precise commutation.

During rapid indexing or transient overloads, the drive may call for a peak current of 144.2 A, enabling the motor to reach a peak torque of 210 Nm without stalling. If the load seizes, the magnetic structure can withstand a locked-rotor peak current of 38.9 A without demagnetization, protecting both the motor and amplifier. The motor has a mass of 45.5 kg, so its frame absorbs thermal spikes and dampens vibration in high-duty machinery.
