Motors and Gearboxes

This wide selection of brushed DC metal gearmotors lets you choose the optimal torque and speed for your particular application. These motors are available in a variety of sizes and gear ratios.

A variety of low-current brushed DC motors with plastic gearboxes that offer power and speed comparable to a continuous-rotation RC servo at a fraction of the price.

Stepper motors allow for precise position control without the need for a feedback system and are capable of continuous rotation, unlike standard hobby servos.

With stroke lengths from 2″ to 12″, these linear actuators are available in several configurations for different linear force and speed requirements. Optional potentiometers allow them to be used in closed-loop position control systems.

Tamiya manufactures a wide variety of inexpensive brushed DC motors and gearboxes that are great for hobbyists and students. Many of the gearmotors are kits that can help you understand how gearboxes work and allow for user-configurable gear ratios.

Pololu item #: 2265
Price: $3.49
Quantity:

This tiny DC motor has a shaft with an offset mass that vibrates when it rotates. Motors like this are commonly found in cell phones and other devices that use vibration for tactile feedback. The motor has 1.5″ leads and is encased in a removable rubber sleeve that gives it flat surfaces for mounting and prevents it from chattering against whatever it is mounted to. It is intended for operation around 3 V (2.4 V to 3.5 V recommended).

This high-power, 130-size brushed DC motor can be used as a direct replacement for lower-power 130-size motors to get more torque and speed out of your gearmotor, but it will also draw more current and typically wear out faster. It has a recommended operating voltage of 1.5 V to 6 V and is compatible with the larger Pololu plastic gearmotors. Approximate specifications at 3 V: free-run speed of 17,000 RPM, free-run current of 250 mA, stall current of 3.85 A, stall torque of 0.75 oz-in.
