1592-POLOLU Brushed DC Motor: 130-Size, 3V, 17kRPM, 3.6A Stall
This high-power, 130-size brushed DC motor can be used as a direct replacement for lower-power 130-size motors to get more torque and speed out of your gearmotor, but it will also draw more current and typically wear out faster. It has a recommended operating voltage of 1.5 V to 6 V and is compatible with the larger Pololu plastic gearmotors. Approximate specifications at 3 V: free-run speed of 17,000 RPM, free-run current of 250 mA, stall current of 3.85 A, stall torque of 0.75 oz-in.
This brushed DC motor is great for applications where you want a lot of power in a small package. We generally recommend running it between 1.5 V and 3 V, but it can operate at higher voltages to provide more power in exchange for longevity of the motor. For example, at 6 V, the speed and torque are approximately twice what they are at 3 V, but it will also draw twice as much current, and it will have a shorter life. In our tests, the motor was able to run continuously at 6 V for approximately five hours before failure.
This motor is a generic alternative to the Solarbotics RM2 motor, offering nearly identical performance in the same form factor. It can be used to provide more speed and torque to gearmotors driven by lower-power 130-size motors, such as our larger Pololu plastic gearmotors (228:1 offset, 120:1 offset, 200:1 90-degree, and 120:1 90-degree) and Solarbotics plastic gearmotors (GM2, GM3, GM8, and GM9). Some people have even been using motors like this to enhance their flywheel NERF guns!
