Mitsubishi's HA-LFS15K1M4, part of the MELSERVO HA series, is engineered as a 400VAC-compatible low-inertia servo motor. This component is rated for an output power of 15 kW, reflecting its strong operational capacity. The continuous torque output is measured at 95.5 N·m, while it can handle peak torque values of 286 N·m, making it suitable for demanding applications.

The motor is nominally rated at 1500 r/min for speed performance. It can reach a top speed of 2000 r/min, with an instantaneous limit extending to 2300 r/min. Regarding electrical specifications, the device has a nominal current of 41 A and a peak current rating of 132 A, ensuring adequate power delivery during operation.

The motor's power density is 309 kW/s, contributing to its efficiency. A significant feature is its moment of inertia, rated at 295 × 10⁻⁴ kg·m², allowing for quick acceleration and deceleration responses. Cooling is achieved through a fully enclosed, force-cooled design that promotes longevity and maintains performance integrity.

With an IP44 enclosure protection rating, this motor provides a suitable barrier against dust and water ingress. Precision is ensured through a high-resolution encoder that generates 131072 pulses per rotation, enhancing control and positioning accuracy. Lastly, the insulation grade of Class F ensures reliable performance under varied thermal conditions.
