Motors & Electric Parts
Every loose LEGO® electric part in one place: motors, battery boxes, wires and connectors, light bricks, sensors and train electrics. From the first 4.5V motors and 12V trains to 9V and Power Functions, new and used, so you can get an old set moving again or add power to your own build.

Which LEGO system do you have?
LEGO has made several electric systems, and each one has its own plugs. 4.5V and 12V parts use round or square pin connectors, 9V uses stud-shaped plugs on a 2 x 2 brick, and Power Functions uses a flat plug that stacks. Parts from different systems usually do not fit together without an adapter, so check the voltage in the part name before you order.
