Electrical Specification *Manufacturer Part Number: 17HE19-2004S *Motor Type: Bipolar Stepper *Step Angle: 1.8 deg *Holding Torque: 55Ncm *Rated Current\/phase: 2A *Phase Resistance: 1.3ohms *Inductance: 2.4.00mH ± 20%(1KHz) Physical Specification *Frame Size: 42 x 42mm *Body Length: 48mm *Shaft Diameter: Φ5mm *Shaft Length: 24mm *D-cut Length: 15mm *Number of Leads: 4 *Lead Length: 1000mm *Weight: 400g Connection A+: Black, A-: Blue, B+: Green, B-: Red Warning: ***On some systems, the middle 2 wires on the motor side are swapped. This is easy to fix by slightly prying back the white nubs and swapping the wires. Otherwise they work fine.*** Make sure the motor connect to a constant current or chopper drive controller before you test motor.  Connecting the motor directly to a power supply will destroy the motor.\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43357950378193,"sku":"BW-B0B93LJPG2","price":77.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/51npES0-2ZL._SL1000.jpg?v=1790987643","url":"https:\/\/belmontwarehouse.com\/products\/stepperonline-nema-17-stepper-motor-2a-55ncm-bipolar-1-8-degree-4-lead-for-3d-printer-cnc-extruder-5-pack","provider":"Belmont Warehouse","version":"1.0","type":"link"}
