Stepper motor, 57mm flange(NEMA23), 3 phase, 3A, 1.4Nm, 6 leads
Three-phase stepper motor, 57mm flange, 3 A/phase, 1.4 Nm / 14.3 kg-cm holding torque, 1.2 degree step angle.
Overview
The M3576T015-8 is a three-phase stepper motor with a 57mm flange (the NEMA 23 class), the only three-phase motor in this catalogue.
It draws 3 A per phase (0.69 ohm winding resistance, 1.8 mH inductance) and holds 1.4 Nm / 14.3 kg-cm at standstill. The step angle is 1.2 degrees, finer than the 1.8 degrees typical of a two-phase motor at this frame size, which is the usual trade a three-phase stepper makes - more steps per revolution for smoother low-speed motion, at the cost of needing a three-phase-specific drive rather than the wider range of two-phase drives elsewhere in this catalogue. It weighs 1.1 kg.
Six lead wires bring the three-phase windings out for connection to a matching three-phase drive - this catalogue's DW3580 (24-50 V DC) or DW3880 (24-100 V DC / 18-80 V AC), both rated for the 1.4-8 A range this motor's 3 A comfortably sits within.
This motor's current and torque figures were corrected from an earlier catalogue listing (5.2 A, 1.5 Nm) after checking against its datasheet; the figures here are the verified ones.

Questions
I've seen different current/torque numbers for this motor elsewhere (5.2 A, 1.5 Nm) — which is right?
3 A and 1.4 Nm are the correct, verified figures — an earlier catalogue listing had it wrong (5.2 A, 1.5 Nm), corrected after checking against the datasheet directly.
Why three-phase instead of the more common two-phase motors you sell?
A finer step angle — 1.2 degrees versus the 1.8 degrees typical of a two-phase motor at this frame size, giving more steps per revolution for smoother low-speed motion. The tradeoff is needing a three-phase-specific drive.
What drive do I need for this?
The DW3580 (24-50V DC) or DW3880 (24-100V DC / 18-80V AC) — both rated for the 1.4-8A range this motor's 3A comfortably sits within.
