Ever-Power Corporation , announces its right position NEMA gearbox made to IP65 specifications for use in clean straight down applications in packaging gear and comparable machinery. Rated backlash is definitely 30 arc-minutes with options for 4 or 8 arc-minutes. The NEMA 34 flanged gearbox has 440C Stainless bearings with seals and Nitrile o-rings shaft seals on both insight and result. All fasteners are stainless steel. Hard anodized light weight aluminum or 316 Stainless housings are available. Customizing for other than NEMA motors or your specific application is easily done.
This Nema 17 stepper motor with 39mm body and 1.68A rated current, integrated with a 41mm Planetary gearbox of 5:1 equipment ratio. It’s a good solution to applications that with unique space but need low rate and/or high torque.

Replaced by the 3325_0, a electric motor with the same NEMA size and same torque.
This NEMA-17 motor has an integrated Planetary gearbox with a 52/11 :1 ratio. It creates 16.2 Kg-cm of torque at 1.68 Amps.
When connected to a 1067 – EP, the 3317 includes a maximum acceleration of just a little over 900 RPM. At the output of the gearbox, the stage angle is just a little under 0.35°. With all the step position in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.
This particular revision of the 3317 is manufactured by a different producer, but should behave very similarly to the revision 0 version.
Brother Gearmotors NEMA C-Face Speed Reducers

Longer Life
Compared to a spur equipment of around the same pitch size, Helical gears may transfer high loads in greater speeds. This is because of the gradual engagement of the teeth and even transfer of the load.
Helical Gears
Lightweight and Compact
Die cast aluminum equipment housings make these velocity reducers light in weight, allowing engineers to design more economical mounting provisions
Maintenance Free
High-quality synthetic grease can be used in all gearboxes. They are loaded at the factory and don’t need maintenance filling or level checks. This saves precious time at create and eliminates concern for pricey oil disposal required by the EPA.
Mount in virtually any Direction
These gearboxes are sealed with machine “slip” suit “O” rings and dual lip springtime shaft seals on both the motor and insight shaft and result shaft driver. Therefore, the gear motors could be mounted in any conceivable direction without concern for the positioning of a breather connect.
