Answer 1

Stepper motors NEMA 17/NEMA 23 series are available in various models

NEMA 23 Stepper Motor 56.4x56.4mm (2.22x2.22in)

Available in seven different power sizes with torque up to 3Nm (425oz-In), the standard NEMA23 flange is always maintained.

The motor shaft can be 6.35 mm (0.250 in.) or 8 mm (0.315 in.) in diameter with flattening (recommended for motors with torque over 1.5 Nm and 213 inches).

The M1233070 and M1233071 models offer high torque in commercially available motors with NEMA23 flanges.

NEMA23 Stepper Motor 0.55Nm (77oz-in) 0.62Arms L=41mm (1.61in)

Technical data:

Bipolar holding torque 0.55Nm (77oz-in)

Bipolar current 0.62 arms

Rotor inertia 150g-cm 2 (0.82oz-in 2 )

Length 41 mm (1.61 inches)

Weight 470 g (16.58 oz)

Flange NEMA 23 56.4x56.4 mm (2.22x2.22 inches)

Full step angle 1.8°

Answer 2

According to customer requirements, stepper motors with keys and dual shafts are available. 

The motor shaft can be 6.35 mm or 8 mm in diameter.

Our company's NEMA23 stepper motors are available in seven different power sizes with torque up to 3Nm (425 oz-inches), always flanged in the standard NEMA23. Some models offer two different wiring to best suit the application.
