NEMA34 2.4nm Stepper Motor L=66mm Gear Ratio 5: 1 Worm Gearbox Nmrv40 Worm Gear Speed Reducer

This Nema 34 size stepper motor is equipped with a 5:1 worm gearbox. The worm gear speed reducer comes with a high-quality, long-term synthetic lubricant, which makes it maintenance free. Its output shaft is offset by 90° from the drive shaft and characterized by high efficiency and self-locking.Strong capacity of loading and overload ensure stable transmission, make less vibration and noise. It's good choice to be applied to CNC Router, Engraving, Milling, Lathe, etc.  Model No     Step AngleRated VoltageRated CurrentPhase ResistancePhase Inductance   (mH)Holding Torque (Kg.cm)Detent Torque  (g.cm Max)Rotor Inertia (g.cm²)Motor Length  (mm)Leads  No.Moto(°)(V)(A)(Ω)Weight    (Kg)86HS65-30041.83.331.16.52880010006541.786HS68-40041.81.340.331.635100012006841.786HS78-40041.81.540.382.535120014007842.386HS78-42041.81.94.20.45445120014007842.386HS78-60081.8360.5445120014007882.386HS82-45041.81.44.50.322.845130015008242.586HS82-56081.825.60.35350130015008282.586HS100-50041.82.550.54682000210010043.286HS100-50081.82.550.54652000210010083.286HS118-60041.83.660.66852400270011843.786HS118-56081.83.45.60.66852400270015683.786HS156-55041.83.95.50.791203600400015645.586HS156-62041.83.66.20.7591223600400015685.5  ItemSpecificationsStep Angel1.8°Temperature Rise80ºCMaxAmbient Temperature-20ºCMax~+50ºCInsulation Resisitance100M ΩMin,.500VDCDielectric Strength500VAC for 1 minuteShaft Radial Play0.02Max (450g-load)Shaft Axial Play0.08Max(450g-load)Max.Radial Force220N(20mm from th flange)Max.Axial Force60NElectrical Specification:Manufacturer Part Number: 86HS85-3004+NMRV40 5ratio Motor Type: Open loop Stepper Holding Torque without Gearbox: 2.8Nm(396oz.in) Rated Current/phase: 3A Phase Resistance: 1.1ohms Inductance: 6.5mH±20%(1KHz) Gearbox Specifications:Gearbox Type: Worm Gearbox Gear Ratio: 5:1 Efficiency: 87% Backlash at No-load:
