NEMA-23 Bipolar Stepper with 77:1 Gearbox

Description

This powerful bipolar stepper with a rear shaft and a planetary gearbox has a 0.023° step angle and 240 kg·cm of torque at low speeds. This NEMA-23 motor has an integrated Planetary gearbox with a 76 49 / 64 :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler . When connected to a 1067 - PhidgetStepper Bipolar HC, the 3334 has a maximum speed of 25 RPM. At the output of the gearbox, the step angle approximately 0.023°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio. At 2.8 Amps, this stepper motor can produce a maximum torque of 960 kg-cm. However, the gearbox is only rated for 240 kg-cm of continuous torque. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life. The 3334 stepper motor connects to a bipolar motor controller such as the 1067 - PhidgetStepper Bipolar HC . The following diagram 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. Note: Make sure to unplug the power cord from the motor controller before switching wires around. The rear shaft of this motor can be equipped with the HKT22 Optical Encoder for applications where you need to keep track of the exact position, velocity, or acceleration of the motor. The mounting holes on this motor are compatible with the 3339 - Mounting Bracket (NEMA23) . Electrical Properties
