DC Motor in Micro Servo Body

This DC Motor in Micro Servo Body combines a compact 4–6V brushed DC motor and plastic gearbox in a micro-servo-sized housing, providing a simple drive option for small robot wheels and vehicles.

This tiny DC Motor in Micro Servo Body is an interesting motor - it's the same size and shape as our micro servo but it isn't a servo. It's more like a DC motor + plastic gear-train in a box.

It's not a super powerful motor, it would do well as a little robot wheel. It's also a lot less expensive than a micro servo (continuous or non-continuous) because there is no control board inside. Controlling speed is done by PWM'ing the power leads, controlling direction is done by swapping the power polarity - just like any brushed DC motor.

Runs from 4-6VDC, we've powered it with a Lipoly and 3 alkaline, or 4 NiMH batteries with success. You cannot control this directly from a microcontroller pin! You must have a H-bridge such as a L293D, TB6612 or a Motor shield, Motor HAT or  DC Motor + Stepper FeatherWing.

Motor comes with 2x screws and 2x nuts for mounting to a chassis. No flanges or horns included - it's intended to mate with the little wheels, there's a screw to attach once they're plugged together. Build a robot vehicle of your own with these little motors driving it!
