Description

Phidgets 28STH32 NEMA-11 Bipolar Stepper with 100:1 Gearbox 3322_0

This NEMA-11 motor has a Planetary gearbox with a 991044/2057 :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. See under Connection & Compatibility for a complete list of attachments.

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. See under Connection & Compatibility for wiring details.

At 0.67 Amps, this stepper motor can produce a maximum torque of 60 kg-cm. However, the gearbox is only rated for 32 kg-cm of continuous torque. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.

Connection
This motor must be controlled by a constant current or chopper drive controller. You can find a list of suitable controllers under Connection & Compatibility. There you will also find compatible attachments such as encoders, mounting hardware, and transmission hardware.

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.

Connection & Compatibility
Motor Controllers
This motor must be controlled by a stepper motor Controller.
Note: Make sure to unplug the power cord from the motor controller before switching wires around.
The following stepper controllers can be used to drive this Motor:

STC1003_1	1/16 Step (40-Bit Signed)	1 1/16 steps/sec	115000 1/16 steps/sec	4:00 AM

Encoders
The rear shaft of this motor can be equipped with an encoder for applications where you need to keep track of the exact position, velocity, or acceleration of the motor. The mounting holes on the back of this motor are compatible with the following encoders:

	Encoder Properties
Part Number	Output Circuit Type	Encoder Resolution	Encoder Speed Max
3531_0	Push-Pull (Single-Ended)	300 CPR	6000 RPM
ENC4109_0	Push-Pull	40 CPR	6000 RPM

Shaft Couplers
If you need to connect the main shaft of this motor to the shaft of another device, you can use a shaft coupler:

Pulleys and Sprockets
If you're using this motor to drive a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of the motor. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance. Here is a list of our 6mm bore pulleys and sprockets:

TRM4162_0	6 mm	22

Mounting Brackets
Mounting this motor to a flat surface is easy with these metal mounting brackets. The holes on the bracket match those on the back of the motor, as well as the ones on the front of the gearbox. The following brackets will fit the mounting holes on this motor:
