NEMA23 3nm Stepper Motor L=112mm Gear Ratio 5: 1 Worm Gearbox Nmrv30 Worm Gear Speed Reducer

This Nema 23 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 Current (A)Phase ResistancePhase Inductance   (mH)Holding Torque (Kg.cm)DetentRotor Inertia (g.cm²)Motor Length  (mm)LeadsMotor Weight(°)(V)(Ω)TorqueNo.(Kg)   (g.cm Max)  57HS41-20041.82211.23.22101204140.4557HS41-10041.85.415.49.55.52101204140.4557HS41-20041.82212.252101204140.4557HS51-15041.82.41.51.63.88.23602755140.6557HS51-20041.82.421.2393602755140.6557HS51-20061.82211.673602755160.6557HS56-15041.85.71.53.81213.54003005640.757HS56-30041.82.8530.952.8124003005640.757HS56-20061.83.621.82.894003005660.757HS64-30041.83.931.32.2155003806440.857HS76-20041.88.624.316.224680480764157HS76-30041.82.730.93.520680480764157HS76-40041.82.440.62.220680480764157HS82-30041.84.231.45227005108241.257HS82-40041.8340.753.5207005108241.257HS100-30041.83314.525100068010041.457HS112-30041.83.931.36.530120080011241.757HS112-35041.82.453.50.7328120080011241.7  ItemSpecificationsStep Angle1.8°Temperature Rise80ºCMaxAmbient Temperature-20ºCMax~+50ºCInsulation Resistance100MΩMin.,500VDCDielectric Strength500VAC for 1 minuteShaft Radial Play0.02Max(450g-load)Shaft Axial Play0.08Max(450g-load)Max.Radial Force75N(20mm from th flange)Max.Axial Force15NElectrical Specification:Manufacturer Part Number: 57HS112-3004+NMRV30 5ratio Motor Type: Open loop Stepper Holding Torque without Gearbox: 3Nm(424oz.in) Rated Current/phase: 3.5A Phase Resistance: 0.7ohms Inductance: 3mH±20%(1KHz) Gearbox Specifications:Gearbox Type: Worm Gearbox Gear Ratio: 5:1 Efficiency: 87% Backlash at No-load:
