Ever-Power Company , announces its right position NEMA gearbox made to IP65 specs for use in clean straight down applications in packaging products and comparable machinery. Rated backlash is 30 arc-minutes with choices for 4 or 8 arc-minutes. The NEMA 34 flanged gearbox has 440C Stainless steel bearings with seals and Nitrile o-bands shaft seals on both insight and result. All fasteners are stainless. Hard anodized aluminum or 316 Stainless housings can be found. Customizing for other than NEMA motors or your unique application is quickly 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 particular space but require low quickness and/or high torque.

Replaced by the 3325_0, a engine 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 has a maximum swiftness of a little over 900 RPM. At the result of the gearbox, the step angle is just a little under 0.35°. When using the step position in calculations, you should derive the specific step position by dividing 1.8° by the gearbox decrease ratio.
This specific revision of the 3317 is made by a different producer, but should behave very similarly to the revision 0 version.

Longer Life
Compared to a spur gear of around the same pitch size, Helical gears may transfer high loads at greater speeds. That is because of the gradual engagement of one’s teeth and smooth transfer of the load.
Helical Gears
Lightweight and Compact
Die cast aluminum equipment housings make these rate reducers light in weight, allowing engineers to create less expensive mounting provisions
Maintenance Free
High-quality synthetic grease is used in every gearboxes. They are loaded at the factory and don’t need maintenance filling or level checks. This saves precious time at set up and eliminates concern for expensive oil disposal necessary by the EPA.
Mount in Any Direction
These gearboxes are sealed with machine “slip” suit “O” rings and dual lip spring shaft seals upon both motor and input shaft and result shaft driver. Thus, the gear motors could be mounted in virtually any conceivable direction without concern for the positioning of a breather plug.
