Ever-Power Corporation , announces its right position NEMA gearbox designed to IP65 specs for use in wash down applications in packaging apparatus 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-bands shaft seals on both input and result. All fasteners are stainless steel. Hard anodized aluminum or 316 Stainless housings are available. Customizing for other than NEMA motors or your specific 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 gear ratio. It’s a good solution to applications that with special space but require low rate and/or high torque.

Replaced by the 3325_0, a 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 generates 16.2 Kg-cm of torque at 1.68 Amps.
When connected to a 1067 – EP, the 3317 includes a maximum quickness of just a little over 900 RPM. At the result 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 specific revision of the 3317 is manufactured by a different producer, but should behave very much like the revision 0 version.

Longer Life
In comparison to a spur equipment of around the same pitch diameter, Helical gears may transfer high loads in greater speeds. That is due to the gradual engagement of the teeth and soft transfer of the strain.
Helical Gears
Lightweight and Compact
Die cast aluminum gear 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 packed at the factory and do not require maintenance filling or level checks. This saves precious time at create and eliminates concern for costly oil disposal required by the EPA.
Mount in virtually any Direction
These gearboxes are sealed with machine “slip” match “O” rings and double lip springtime shaft seals on both the motor and input shaft and output shaft driver. Thus, the gear motors can be mounted in virtually any conceivable path without concern for the positioning of a breather connect.
