Motor CHFGM12N20ABHL — DC Gear Motor with 7PPR Encoder, Carbon Brush, Gear Reducer (6V / 12V, 6V 200rpm, i50) Key benefits Reliable lowspeed, torque output: the integrated gear reducer (i50) converts motor speed into a controllable, torqueenhanced output ideal for driving mechanisms without oversized motors. Builtin encoder for feedback: the 7PPR encoder (7 pulses per revolution) provides basic position and speed feedback for closed‑loop control, sensor fusion, and repeatable motion. Simple, costeffective power and maintenance: carbon brush DC design offers strong starting torque and compatibility with common DC power supplies (6V or 12V), making it easy to integrate and . Versatile and compact solution: designed for small electromechanical systems where space, feedback, and reduced speed are required. What this motor solves Eliminates the need for a separate gearbox and external encoder by combining reduction and feedback into one compact unit. Reduces development time: plugandplay compatibility with DC drive circuits and encoderreading electronics accelerates prototyping and product development. Improves control in lowspeed applications by providing encoder pulses for accurate speed regulation and positioning. Key attributes and specifications Model: CHFGM12N20ABHL Motor type: Carbon brush DC gear motor (motor reducer) Voltage: DC 6V / 12V operation Rated speed example: 6V > 200 rpm (as indicated) Gear ratio: i50 (50:1 reducer) Encoder: 7PPR (7 pulses per revolution) incremental encoder Construction: DC brushed motor with integrated gearbox and encoder Typical use: directdrive small mechanisms where reduced speed, increased torque, and encoder feedback are required Compatibility and integration Works with standard DC power supplies at 6V or 12V and common motor drivers supporting brushed DC motors. Encoder output can be read by microcontrollers, motor controllers with encoder inputs, or external counting/logic circuits that handle incremental encoder signals. Mechanical mounting and shaft dimensions vary by model variant; verify fit against your chassis or mounting brackets before installation. Recommended applications (use cases) Mobile robotics and differential drive: use for drive wheels or steering actuators where moderate speed, good torque, and encoder feedback improve navigation and closedloop control. Small automation and positioning systems: suitable for conveyor drives, miniature linear actuators, or rotary indexing tables where precise speed and position feedback are required. Educational and hobby projects: ideal for makers, prototyping, and classroom projects that need a compact gear motor with feedback for experimentation and learning. Installation and operation tips Supply the motor with a stable 6V or 12V DC source appropriate for your intended speed and torque requirements. Read the 7PPR encoder with an interruptcapable input or encoder interface to achieve reliable counting and speed measurements. Because this is a carbonbrush motor, expect normal brush wear over longterm heavy use; plan for inspection and replacement intervals if used in continuous load applications. Use appropriate motor drivers that include current limiting or braking features if your application requires stopping under load. Why choose CHFGM12N20ABHL Integrated gearbox and encoder reduce component count and simplify mechanical and electrical integration. Flexible voltage options and a clearrated example speed (6V → 200 rpm) make it straightforward to predict behavior in your design. A practical choice for projects that require reliable lowspeed performance, encoder feedback, and a compact footprint without moving to more complex motor types.
