Ever-Power Company , announces its right position NEMA gearbox made to IP65 specifications for use in clean down applications in packaging apparatus and comparable machinery. Rated backlash is definitely 30 arc-minutes with choices for 4 or 8 arc-minutes. The NEMA 34 flanged gearbox has 440C Stainless bearings with seals and Nitrile o-bands shaft seals on both insight and output. All fasteners are stainless. Hard anodized light weight aluminum or 316 Stainless housings are available. Customizing for other than NEMA motors or your unique 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 gear ratio. It’s a great choice to applications that with special space but require 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 comes with an integrated Planetary gearbox with a 52/11 :1 ratio. It creates 16.2 Kg-cm of torque at 1.68 Amps.
When linked to a 1067 – EP, the 3317 has a maximum swiftness of a little over 900 RPM. At the output of the gearbox, the step angle is 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 specific revision of the 3317 is manufactured by a different manufacturer, but should behave very similarly to the revision 0 version.

Longer Life
Compared to a spur equipment of approximately the same pitch diameter, Helical gears may transfer high loads in greater speeds. This is because of the gradual engagement of one’s teeth and easy transfer of the load.
Helical Gears
Lightweight and Compact
Die cast aluminum equipment housings make these speed reducers light in weight, allowing engineers to create less expensive mounting provisions
Maintenance Free
High-quality synthetic grease is used in all gearboxes. They are packed at the factory , nor 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” fit “O” rings and dual lip spring shaft seals on both motor and input shaft and result shaft driver. Therefore, the gear motors can be mounted in virtually any conceivable path without concern for the position of a breather connect.
