NEMA17 - JK42HS40 - 1.7A - 40mm Stepper Motor

NEMA17 stepper motors are the most popular motors used in the construction of 3D printers, milling machines, plotters and other electronically controlled devices. The middle part where the coils are wound consists of a number of ferromagnetic plates connected to each other. Strong neodymium magnets ensure precise work. The kit includes 4 wires connected with a plug dedicated to stepper motors. On the other hand, the cable is terminated with a 4-pin pin plug, which allows direct connection to stepper motor controllers such as, for example, a set for building a RAMPS 3D printer or SHIELD for a CNC machine tool and many others. Product features High starting speed Get precise angular movements at a reasonable price It can be used to activate disk transistors in the correct order The ease of operation makes the engine convenient to use Motors with a wide range of applications, used in 3D printers, monitoring devices, packaging machines, stage lighting, etc. Technical data Model JK42HS40-1704-13A Standard: NEMA17 Step: 1.8 * Steps per revolution: 200 steps Voltage: 2.8V Current 1.7A / phase Resistance: 1.65 Ohm / phase Inductance: 3.2 mH / phase Holding torque: 4000 g-cm Inertia / Rotor interia: 54g-cm2 Number of wires: 4 Weight: 290g Shaft diameter: 5mm Dimensions: 42 x 42 x 40 mm (without shaft)
