Phidgets 3329_0 Bipolar Stepper
This NEMA-17 motor has an integrated planetary gearbox with a gear ratio of 991044/2057:1. The rear shaft is exposed, so you can mount an encoder or shaft coupler.
At the output of the gearbox, the step angle is about 0.018°. If you use the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gear reduction ratio.
At 1.7 amps, this geared stepper motor can produce a maximum torque of 250 kg-cm. However, the gearhead is only rated for 48 kg-cm of continuous torque and 100 kg-cm for short overloads. If this geared stepper motor is loaded beyond the rated torque of the gearbox, its service life will be shortened.
Connection
This motor must be controlled by a constant current or chopper drive controller.
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.
