Product Description:

The LSM215-589-204-M-0KA is a brushless servo motor produced by Kollmorgen within the LSM Brushless Servo Motors series. The unit converts electrical energy into controlled rotary motion for positioning tables, presses, and other automated axes that require high torque density and repeatable speed regulation. Its compact frame contains a wound stator and permanent-magnet rotor, allowing the motor to connect directly to a compatible digital drive for closed-loop motion control.

At its rated operating point, the motor provides a continuous shaft torque of 66 Nm while running at a nominal speed of 2000 rpm. For rapid indexing or overcoming breakaway friction, it can deliver a peak torque of 210 Nm when the drive supplies a peak current of 144.2 A. The electromagnetic design provides a torque constant of 1.84 Nm/A, allowing the servo controller to calculate output torque from the commanded current. Eight magnetic poles and a voltage constant of 222 V/kRPM align the electrical frequency with industrial inverter outputs. The motor has a peak stall current of 38.9 A, which indicates the current demand when the rotor is stationary under load. Its rotor inertia is 0.0077 kg·m², an important value for setting current-loop gains and acceleration limits during dynamic duty cycles.

The motor has a winding inductance of 7.4 mH, while its copper resistance at 25 °C is 0.31 ohm. These electrical values influence current ripple and winding temperature during continuous operation. Mechanical installation is supported by an M12 × 1.75 shaft thread cut to a depth of 28 mm. The motor can withstand a radial load of 112 kg at nominal speed without causing premature bearing wear. Power is supplied from a three-phase line rated at 460 V, matching a common industrial distribution voltage. A net mass of 45.5 kg provides substantial thermal mass for steady operation while allowing the housing to be handled with suitable lifting equipment.
