What can I use the motors for?

Whether you need a high or low powered motor this kit has you covered with two motors one 1.5-3V and the other 3-6V. Both motors come with their own holder for attaching them to a flat surface. A battery box for two AA batteries is also included in the kit to act as your power supply (AA batteries not included Order Code L43AL). These motors are great for hobbies modelling applications and demonstrating the difference that torque and rpms can make on a system.

What are the specifications for the motors?

The MM28 battery operates on 3-6V with rotary speeds that can reach up to 14700 rotations per minute and torque up to 26.5gf.cm. With its compact size just 24.2mm in diameter and 32.5mm (45mm including the 2mm shaft) long and powerful rpms this is a great addition to any project.
The MM12 motor is even smaller at 21mm in diameter and 28mm (38mm including the shaft) long. The 1.5-3V motor can achieve up to 11,500 rotations per minute and 10.9 gf.cm of torque. With its 2mm shaft the same as MM28 the two motors can be easily interchanged for experiments or to show the difference they can make to a system. Both motor can be run in either direction by reversing the input polarity.
