Product Description:
The LSM165-119-454-S-2KA is a brushless rotary servo motor produced by Kollmorgen for the LSM Brushless Servo Motors series. It converts current from a compatible servo drive into controlled shaft torque for precise rotary motion. This operating principle supports repeatable positioning and speed regulation as external loads change during a production cycle. Typical applications include positioning tables, pick-and-place heads, packaging axes, and other automated mechanisms that require responsive acceleration and accurate stopping.
The motor provides a continuous torque output of 13.5 Nm and can produce a short-term peak torque of 51 Nm during acceleration or transient loading. Its rated speed is 4500 rpm, supporting rapid motion in applications that require a broad operating range. A torque constant of 0.87 Nm/A relates applied current to generated torque, while a voltage constant of 105 V/kRPM describes the back electromotive force produced as rotational speed increases. The stall current is 16.4 A(pk), and the servo drive must supply up to 70.7 A(pk) for peak torque events. The phase resistance is 0.76 Ω, which affects winding losses and the voltage required to regulate current under load. These electrical values allow a compatible drive to control torque throughout acceleration, steady motion, and deceleration.
The integrated brake operates from a 24 VDC source and can hold the shaft when commanded by the control system. The motor assembly weighs 18.5 kg, which must be considered when selecting the mounting surface and supporting machine structure. Its rotor inertia is 0.00127 kg·m², supporting load matching and responsive speed changes. Position feedback is provided by a single-turn Sin/Cos encoder, which supplies continuous angular information to the servo drive for closed-loop control. The phase inductance is 6.68 mH, moderating the rate of current change when the drive applies a high-frequency pulse-width modulated waveform. A keyed shaft uses an 8 mm-wide key to provide positive torque transfer to a coupling, pulley, or gearbox. The shaft terminates in an M10 × 1.5 mm thread with a depth of 22 mm, allowing the attached component to be secured while limiting unnecessary overhang.
