Frame: M-403 (40-size modular)

Stack: B

Winding: A2

Feedback Mount: B3 (resolver or encoder mount code)

Rated Torque: 8–12 Nm (estimated by frame)

Rated Speed: 2000–4000 rpm

Voltage Class: 300 VDC class

Configuration: Stator + rotor kit (no housing)

Functional Features:​ High torque density, configurable shaft/bearing by OEM, low cogging variants available, direct integration into machine structure.

Construction / Materials:​ Stator lamination stack with epoxy potting, rotor with bonded NdFeB magnets, no shell.

Working Principle:​ Same BLDC commutation; machine builder supplies housing, bearings, shaft, feedback.

Mounting Requirements:​ Press-fit stator into machined bore (H7 tolerance), rotor mounted on customer shaft with defined airgap 0.5–1.0 mm; feedback mounted on B3 bracket.

Usage Notes:​ Not a drop-in motor—requires mechanical integration. Airgap concentricity < 0.05 mm mandatory. Use only with drives supporting modular motor params.
