JoyNano – Enjoy Electronics and Gadgets JoyNano NEMA 17 Stepper Motor with Integrated 310mm T8 Lead Screw, no shaft coupling needed. Each phase draws current 1.68A, allowing for a holding torque of 40Ncm. Easy to install, durable with alloy steel material. Features: High Stability: No shaft coupling needed,integrated with stepper motor and lead screw. Holding torque up to 0.4Nm(56.2oz-in), low loss stators have better high speed performance. 2-phase 4-wire, 30cm lead wire with XH2.54 connector,no soldering or peeling works. Precisely machined full metal body, heat shrink tubing effect to prevent the wire tangled up. Great replacement for the Z axis of prusa i3 3d printers. Wire Connection: Black(A+), Green(A-), Red(B+), Blue(B-) Electrical Specification: Motor Type: Bipolar Stepper Step Angle: 1.8 deg. Rated Current/phase: 1.68A Phase Resistance: 1.65Ohm±10% Phase Inductance: 3.2mH±20% Holding Torque: 40Ncm(56.2oz) Rotor Inertia: 54g2 Orientation Torque: 150g Physical Specification: Frame Size: 42 x 42mm Body Length: 40mm Lead Screw Lengh:310mm Number of Lead wire: 4 Wire Length: 30cm Warning: It should be connected to a constant current or chopper driver as a stepper motor. Connecting the motor directly to a power supply will destroy the motor. Package Included: 1x JOYNANO NEMA 17 Stepper Motor with Integrated 310mm T8 Lead Screw
