Special motor Circuits DC Worm Gear electronic starter — 6V / 12V / 24V — 40:1 Metal Reducer with 11 PPR Encoder (Color: DC 6V, Size: 18) Why choose this gearmotor torque, compact size: the worm gear and 40:1 metal reducer deliver strong output torque in a compact 'Size 18' package, ideal where space is limited but power is required. Precise feedback for smart control: the builtin 11 PPR incremental encoder provides reliable position and speed feedback for closedloop control with microcontrollers and motor drivers. Robust and reliable: metal gearbox and wormgear design increase durability and offer selflocking characteristics for holding loads without backdriving. Flexible power options: available for 6V, 12V, and 24V systems to match batterypowered toys, small robots, or industrial control circuits. This listing shows the DC 6V color option. Key features and specifications Motor type: DC worm gear motor with electronic starter functionality as specified. Voltage options: 6V, 12V, 24V (this model listing: DC 6V color). Gear ratio: 40:1 for torque output at lower speed. Reducer: metal gearbox for improved wear resistance and heat dissipation. Encoder: 11 PPR (pulses per revolution) incremental encoder for speed and position sensing. Size: 18 (compact form factor suitable for spaceconstrained designs). Performance focus: designed for torque output, consistent feedback, and reliable mechanical reduction. How this product solves common problems Replaces weak plastic gears: the metal reducer resists stripping and wear common in lowcost motors. Provides accurate motion control: the 11 PPR encoder enables precise speed regulation and position tracking for automated or programmable projects. Prevents unwanted backdrive: wormgear selflocking helps hold mechanisms in place without additional brakes, simplifying design and improving safety. Adapts to different power systems: available voltages let you match the motor to your power source without complex modifications. Compatibility and integration Works with standard DC motor drivers and controllers compatible with 6V, 12V, or 24V motors. Encoder output can be read by common microcontrollers (Arduino, Raspberry Pi, STM32, etc.) with appropriate signal conditioning. Mechanically suited for hobby robotics, RC and smart toys, small automation projects, and custom mechatronic fixtures. Wiring and mounting follow common motor/gearbox conventions for straightforward installation; confirm connector and shaft dimensions against your design. Practical use cases 1) Smart toy engine and robotics: use this motor to drive wheels, steering mechanisms, or articulated joints on programmable toys and educational robots that need both torque and encoder feedback for autonomous control. 2) Automated latches and small actuators: the worm gear's selflocking behavior and torque make it ideal for small doors, locks, or mechanical actuators where holding force without constant power is required. 3) Prototype machines and hobby automation: integrate with Arduino or other controllers to build conveyor segments, camera pan/tilt heads, or slowspeed indexed mechanisms where precise position/speed feedback improves performance. What's included / what to check before Worm gear DC motor with 40:1 metal reducer and builtin 11 PPR encoder, Size 18 (DC 6V color option as listed). Confirm required operating voltage (6V, 12V, or 24V) and choose the matching version for your project. Verify mounting and shaft dimensions to ensure mechanical compatibility with your setup. Ensure your control electronics accept the encoder's pulse rate and the motor's current draw at the selected voltage. Practical tips For precise control, pair the 11 PPR encoder with an interruptcapable microcontroller and implement simple filtering or debouncing on encoder inputs. Use an appropriate motor driver rated for the motor's stall current and your chosen voltage to protect both the motor and controller. If using the selflocking property for holding loads, test under expected load conditions to confirm holding torque meets your needs. Reliable, compact, and feedbackready This DC worm gear motor with 40:1 metal reducer and 11 PPR encoder blends durability, torque, and position feedback in a compact Size 18 package. It is suitable for toy engines, smart control applications, robotics, and small automation tasks where precise control and dependable mechanical performance are required.
