PS3015KN002 is an NSK Megatorque PS Series (PS3 mid size) direct-drive motor. PS3 is the mid size of the PS series (dia. 150 mm) with four heights covering 15–90 N·m.
Why zero-backlash direct drive: Megatorque motors drive the load directly without gears or belts — no backlash, no wear parts, no accuracy degradation over time, fast settling, low noise and maintenance-free. The large hollow bore (56 mm on this model) passes cables, piping or laser paths straight through, simplifying machine design. Widely used in semiconductor/electronic-component inspection, vision processing and rotary indexing stages.
Key specs: maximum output torque 15 / 15 N·m (rated 5 / 5 N·m), max speed 10 / 4 s⁻¹; a built-in absolute position sensor (2,621,440 count/rev) delivering ±2 arc-sec repeatability and 60 (±30) arc-sec absolute accuracy; allowable axial load 2,000 N, allowable moment load 42 N·m, mass 5.5 kg. Pairs with the EDD driver unit series (100–240 VAC per the NSK pairing table). An EtherCAT-compatible driver option is available for this model (NSK catalog E3516). See the attached official catalog for dimensions and speed–torque characteristics.
Same-series part numbers: PS3030KN002, PS3060KN002, PS3090KN002.
Sizing & Integration Support
Direct-drive motor sizing involves the inertia ratio (load inertia / rotor inertia) and the motion profile against the speed–torque curve. Add your load conditions (inertia, motion angle, cycle time, mounting orientation) to the inquiry cart — the Nahshon engineering team will help you select the right model and confirm specs, quotation and delivery with NSK.
