Product Description
Mitsubishi TM-RFM012E20ES-S1
The Mitsubishi TM-RFM012E20ES-S1 is a high-performance direct drive (DD) servo motor designed for applications demanding exceptional precision, stability, and a compact footprint. As part of the MELSERVO-J4 series, this motor features a hollow shaft structure, which allows for easy wiring and piping, simplifying machine design. By eliminating mechanical transmission components like gearboxes and belts, the TM-RFM012E20ES-S1 provides backlash-free operation, reduced maintenance, and quieter performance. Its integrated high-resolution 22-bit absolute encoder ensures superior positioning accuracy and smooth, low-speed rotation, making it an ideal solution for indexing tables, semiconductor manufacturing equipment, and precision automation systems.
