NEMA-17 Bipolar 99.51:1 Planetary Gearbox Stepper

ID: 3319_1
This bipolar stepper with planetary gearbox has a 0.018° step angle and 48 kg·cm of torque at low speeds.

Discontinued
Replaced by the 3329_0, a motor with the same torque and speed.

This NEMA-17 motor has an integrated Planetary gearbox with a 991044/2057 :1 ratio. At 1.6 Amps (maximum current), this gearbox stepper can produce a maximum torque of 250 kg-cm. However, the gearbox is only rated for 48 kg-cm of continuous torque, and 100 kg-cm for brief overloads. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.

At the output of the gearbox, the step angle is approximately 0.018°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.

This particular revision of the 3319 is made by a different manufacturer, but should behave very similarly to the revision 0 version.

The 3319 stepper motor connects to a bipolar motor controller such as the 1067 - PhidgetStepper Bipolar HC.

The following table shows how to connect the motor wires to the board connectors to produce a clockwise rotation in the stepper motor when increasing position. To wire for counter-clockwise rotation when increasing position, reverse the red and blue wires.


Wire Color Black Green Red Blue
Board Connector A B C D

Note: Make sure to unplug the power cord from the motor controller before switching wires around.



Warning


warning Connecting the motor directly to a power supply will destroy the motor and void the warranty. If you want to check your motor make sure it is connected to a constant current / chopper drive controller.

The mounting holes on this motor are compatible with the 3338 - Mounting Bracket (NEMA17).
