Product Description:
The LSM165-119-454-E2-0KA brushless servo motor is manufactured by Kollmorgen within the LSM Brushless Servo Motors series. This rotary actuator is intended for precision positioning and velocity control in automated equipment such as gantry axes, packaging stations, and test stands. It supplies closed-loop torque to move mechanical loads according to commands from a compatible servo drive. Its brushless design uses electronic commutation, which supports controlled acceleration, steady-speed operation, and accurate positioning without the wear associated with mechanical brushes.
The motor delivers a continuous shaft torque of 13.5 Nm when operated within its thermal limits. Transient events are supported by a peak torque of 51 Nm, allowing the motor to accelerate loads or respond to brief increases in demand. The rated output speed is 4500 rpm, providing the velocity needed for mid-power conveyor segments, extruder feed rolls, and rapid-index fixtures. The eight-pole rotor operates with synchronous excitation from a 460 V inverter. A torque constant of approximately 0.87 Nm/A establishes the relationship between motor current and generated torque. This relationship allows the servo drive to regulate torque through its current loop while preserving control margin for rapid command changes.
The three-phase stator has an inductance of 6.68 mH and a resistance of 0.76 Ω per phase. These electrical characteristics provide a responsive current rise while helping limit excessive ripple during command changes. During demanding acceleration or deceleration cycles, the winding can accept up to 70.7 A, subject to the applicable duty cycle and thermal limits. The back-EMF coefficient is 105 V per 1,000 rpm and must be considered when matching the motor to a servo drive. The rotor inertia is 0.00092 kg·m², allowing the shaft to respond quickly when paired with a suitably matched load. Position feedback comes from a 2,000-line incremental encoder, which enables the controller to interpolate position and monitor shaft movement. A keyway shaft provides positive engagement with compatible couplings, pulleys, or gearboxes. The motor weighs 16.2 kg, which must be accommodated by the machine mounting surface. It is supplied without a brake, so an external clamp or drive-based holding function is required when the load must remain stationary after motor power is removed.
