New low price!

This 1000RPM gear-motor is a high performance miniature brushed motor and gearbox combo, packing a mighty punch into a small and lightweight package. Sold fully assembled, pre-greased and ready to drop straight into your 1-3kg robotics project.

Note, there are many similar 25mm gearmotors on the market. Through our own research and testing in robotics applications, we have determined that there are low power and high power models, and it is almost impossible to determine which is which from product photos.

Not only is our motor guaranteed to be “the good type”, but we have pre-threadlocked and replaced the main screws in the gearbox as upgrades, to ensure the highest performance and toughness!

Key stats:

  • Overall dimensions: ø25mm*67mm (including shaft and motor tabs).
