GA12-N20 12V gear motor

Product detailed description

The GA12-N20 is a compact DC motor with an all-metal gearbox for a rated voltage of 12 V. With a diameter of just 12 mm, the gearbox provides low speeds and decent torque, making it suitable for powering small robot wheels, linear actuators, rotating and lifting mechanisms, latches, models, or camera movements. You can choose from seven variants with no-load speeds ranging from 60 to 2000 RPM – the lower the speed, the higher the torque. The 3 mm diameter output shaft features a D-flat end to ensure that mounted wheels or couplings do not slip.

Specifications:

Package contents:

• 1× GA12-N20 12V geared motor (according to the selected RPM variant)

Note:

• Control the motor via an H-bridge or transistor; never connect it directly to a microcontroller output.
• The stated speeds apply to no-load conditions; they decrease under load while current consumption increases.
• Fit the wheel, pinion or coupling onto the shaft without impact – a shock to the shaft will damage the gearbox gearing.
• Do not exceed the rated voltage; higher voltage shortens the lifespan of both the gearbox and the brushes.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
