25mm DC Metal Encoder Gearmotors

What is the encoder resolution and how do I wire the encoder to a microcontroller?

The encoder provides 11 counts per revolution of the motor shaft. The encoder pins are VCC for the encoder, GND for the encoder, and OUT1 and OUT2 for the pulses; connect VCC to 5V (3.3 to 5V support) and GND to ground, with OUT1 and OUT2 to digital inputs on your microcontroller.

What gear reduction options are available and how do they affect speed and torque?

The product family includes reduction ratios of 12, 16, 35, 60, 130, and 280. Higher reduction yields lower output speed and higher torque, with the corresponding load speed and torque values shown in the specifications.

What voltages and currents should I expect when using these motors at 6V, 12V, or 24V?

Stall current is 1.8 A at 6V, 1.3 A at 12V, and 0.7 A at 24V. No load current is below 0.10 A at 6V, below 0.06 A at 12V, and below 0.04 A at 24V; at load current is about 0.45 A for 6V and 12V, and 0.25 A for 24V.

Is the encoder compatible with common microcontrollers and how is the encoder powered?

Yes, the encoder operates from 3.3 to 5 V and provides digital outputs that can be connected directly to digital inputs on a microcontroller.

What is the physical size and shaft configuration for these motors?

The motor body is 25 mm in diameter. Gear box lengths vary by variant from 19 mm to 27 mm, and the encoder version uses an extended back shaft.
