Extremely compact stepper motors with integrated spur gear reduction, and with a controller/driver. 24mm gear motor with controller shown. High gear ratios produce 1-3 rev/sec output with considerable torque--25-50 oz-in. Three diferent sizes to fit your application. Select the controller that matches the amperage of your stepper motor. The 1A-TTL can drive up to .1 amps, 0.75 being normal.Use for camera rotation, small door open/lock mechanisms, miniature actuators, small leadscrews, and hundreds more applications. These gear motors are great replacements for solenoids! Solenoids either won't actuate or destroy themsleves, so a geared stepper motor provides very long life and consisitent reliable operation. Backlash is 1-3 degrees, and add a simple spring to reduce reduce that to zero. Two mounting ears provided. These gear motors are unipolar 5Vdc and 7.5 deg/step.

These controllers are microminiature and exceptionally small, see the motor/controller drawings for dimensions. Email info@excitron.com for more details, and for available options.
