Product Description:

LSM130-78-454-M-2KA is a brushless servo motor designed for industrial automation, with performance characteristics that make it suitable for demanding applications. The motor delivers a peak torque of 38 Nm and a continuous torque of 8.8 Nm, important for applications needing high force and maintained performance through varying loads, with efficiency enhanced through its design which minimizes energy consumption and heat generation, thereby increasing operational lifespan. Its manageable weight of 10 kg facilitates easier installation and integration into existing systems, and its operation at a motor speed of 4500 rpm ensures precision for applications like robotics.

The motor includes vital electrical characteristics, and among these is a voltage constant of 107 V/kRPM, which defines the relationship between the back EMF voltage and rotor speed, allowing precise control through varying operating conditions and further enabling speed control through appropriate voltage regulation. With a winding inductance of 8.46 mH, the motor stabilizes current flow, diminishing electrical noise and reinforcing dependable performance through sustained operations. This motor also features a winding resistance of 1.68 Ohm at 25°C, important for managing heat dissipation and ensuring operational effectiveness in diverse conditions. Moreover, the design includes a shaft crafted from ST-60 steel, providing a robust interface for power transmission.

Specific mechanical configurations detail the ways for successful integrations, with a mounting flange diameter of 130 mm that makes it adaptable into various mechanical setups. The motor incorporates M8 x 1.25 mm threads at a 19mm depth, offering solid and secure mounting options for robust operation. The stall current stands at 10.7 amps (peak) and the maximum current at 50.9 amps (peak), providing insights into power usage under different load conditions.
