SparkFun – Small Stepper Motor

SparkFun: ROB-10551

Description: These small steppers are a great way to get things moving, especially when positioning and repeatability is a concern.

When using a current limiting driver such as the Easydriver or Big Easydriver, a 12 volt power supply can be used as long as you adjust the current level to 400mA or less. If using a non current limited driver (like a L293D or an H-bridge) you will need to lower your input voltage to keep the motor current below 400mA.

This is a Bipolar motor.

Features:

• Stride Angle (degrees): 7.5
• 2-Phase
• Rated Voltage: 12V
• Rated Current: 400mA
• 3mm Diameter Drive Shaft
• 4-Wire Cable Attached
• In-traction Torque: 100 g/cm
