Its compact 66x19mm metal body is engineered for durability and easy integration with Arduino and 3D printer applications, making it ideal for robotics, RC models, and custom servo projects. ## Description The rear of the motor is equipped with a dual channel Holzer effect encoder, AB dual output, single circuit per cycle pulse 12PPR, double down the road, a total output of 48CPR. Phase difference 90 degrees. The two-channel Hall effect encoder is used to sense the rotation of a magnetic disk on a rear protrusion of the motor shaft. The quadrature encoder provides a resolution of 48counts per revolution of the motor shaft. To compute the counts per revolution of the gearbox output, multiply the gear ratio by 48. Notice: 1.Be sure to keep the wiring connection correct before Working; 2.Be sure to keep the motor stopped before change the CCW/CW direction; Or the motor will be burned!!! Review: No da las rpm qué prometen, es muy baja su velocidad incluso sin la caja reductora, le realice varias pruebas con su caja reductora y sin ella, el puro motor sin caja reductora no alcanza buena velocidad, parece más un motor de 100 rpm qué de 300 rpm. Review: Good motor, works as expected. I use it for my small robot. Encoder works fine too. Company provides a code for Arduino in C++, which handles encoder data and controls motor with motor class. This code contains PID controller lines, but I am not using this. I modified this code for my needs, but I did not change a core part about encoder which works fine. Finally: this is a good motor. It can be used to drive small robot. Maybe RPM is high for this, but it is acceptable for small carts. ## Features - ✔Product type: DC Gear motor with two-channel Hall effect encoder;Rated Voltage: 12V; No-Load Speed: 300RPM; No-Load Current: ≤ 0.15A; Rated Torque: 0.5kg.cm; - ✔Main Body Dimensions: 66 x 19mm / 2.6in x 0.75in (L*D); Out Shaft Dimensions: 11 x 4mm / 0.433 x 0.1575in (L*D) with 10 x 0.5mm / 0.39 * 0.017inches flat cut off; - ✔Single Output 240 Pulses Per Revolution: Gear Reduction Ratio: 1/20, Each Loop Output Pulses: 12PPR 20*12=240PPR; - ✔Wiring Diagram: Red - Motor power terminal (+); Black - Motor power terminal(-); Green - Quad encoder Ground; Blue - Quad encoder +5V Vcc; Yellow - Quad encoder A signal; White - Quad encoder B signal. - ✔Application: Suit for Projects Such as Robotics, RC Car Model, Custom Servo, Arduino and 3D Printers, DIY Engine Toy. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07GNGCNK1 | | ASIN | B07GNGCNK1 | | Batteries Included? | No | | Batteries Required? | No | | Color | 12V | | Customer Reviews | 4.2 4.2 out of 5 stars (37) | | Customer reviews | 4.2 4.2 out of 5 stars (37) | | Date First Available | 21 September 2018 | | Date First Available | 21 September 2018 | | Horsepower | 2.5 Watts | | Is Discontinued By Manufacturer | No | | Item Weight | 272 g | | Manufacturer | Bemonoc | | Manufacturer | Bemonoc | | Manufacturer reference | 25GA370H-12V300RPM | | Manufacturer reference | 25GA370H-12V300RPM | | Material | Metal | | Part number | 25GA370H-12V300RPM | | Product Dimensions | 7.4 x 2.44 x 2.44 cm; 272 g | | Product Dimensions | 7.4 x 2.44 x 2.44 cm; 272 g | | Speed | 300 RPM | | Voltage | 12 Volts | ## Product Details - **Brand:** Bemonoc - **Horsepower:** 2.5 Watts - **Model name:** Hall Encoder DC Geared Motor - **Speed:** 300 RPM - **Voltage:** 12 Volts ## Images ![Encoder Metal Gearmotor 12V DC High Speed 300RPM Gear Motor with Encoder for Arduino and 3D Printers - Image 1](https://m.media-amazon.com/images/I/51+JncrV17L.jpg) ## Questions & Answers **Q: What is the max amp rating? Stall.** A: Hello, the stall amp is about 2A, thanks! **Q: The information says to multiply the gear ratio by 48, what is the gear ratio of 15 RPM motor?** A: Hello, the gear ratio of 15rpm motor is 362, thanks! **Q: What is the stall torque?** A: Hello, the stall torque is 4.8kg.cm, we don't recommend you to use the motor with stall torque, it's easy to be broken, thanks! **Q: Does the motor have built in contacts for limit switches?
