Motor and wheel
This version of our 90RPM in-line geared TT hobby motor comes with pre-attached wires that terminate in crocodile clips and is a great cost-effective solution for adding some movement to your buggy/robot builds. It can be used with our matching wheels and with our motor driver boards, such as our Kitronik Klip Motor Driver for BBC micro:bit. Note: when using a microcontroller, do not drive these motors directly with the microcontroller, always use them in conjunction with a motor driver board.
Despite their low price point, these brightly coloured 48:1 motors are quite durable and are likely to last through multiple builds with ease. The crocodile clips mean that your builds can be super simple and solder-free!
Although there is a gearbox between the motor and the shaft, there are no rotary encoders. When connected to an appropriate motor driver, like the two listed above, you get forwards/backwards/stop. Simple yet effective. With 2 motors connected to a motor driver, you can also have directional control by turning off one motor and not the other. As is sometimes the case with servos and motors, there can be some small RPM differences between motors which can be overcome when coding, a little trial end error and the odd pause is usually all it takes.
These hobby motors have an operating voltage of between 3V and 6V, with 4.5V being nominal. This makes them suitable for powering with batteries. At 4.5V, they have a speed of 90RPM no-load and 72RPM at load. Torque at the nominal 4.5V is 0.3Kg/cm and they have a stall torque rating of 1.4Kg/cm. See Datasheet for more information.
