M-PN4135KG001 is an NSK Megatorque PN Series with brake direct-drive motor. The PN with-brake type integrates a non-backlash, negative-actuated holding brake (engaged at power-off), for vertical or inclined axes that must hold position on power loss.
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 (32 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 135 (200 VAC only) N·m (rated 45 (200 VAC only) N·m), max speed 3 (200 VAC only) 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 9,500 N, allowable moment load 160 N·m, mass 34 kg. Pairs with the EDD driver unit series (100–240 VAC per the NSK pairing table). See the attached official catalog for dimensions and speed–torque characteristics.
Same-series part numbers: M-PN3045KG001.
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.
