special motor Circuits DC Worm Gear electronic starter — 6V / 12V / 24V, 40:1 metal reducer with 11 PPR encoder, Torque Gearmotor (Color: Dc 6v, Size: 6) A compact, durable gearmotor designed for precision motion and reliable starting in small electromechanical projects. The worm gear drive delivers torque and strong holding capability while the builtin 11 PPR encoder provides position feedback for closedloop control. Available for 6V, 12V and 24V systems; this listing is the DC 6V, Size 6 variant. Key benefits torque, lowbackdrive worm gear: provides strong output force and inherent selflocking for stable holding without extra brakes. Integrated encoder for control: 11 PPR (pulses per revolution) encoder supplies pulse feedback for speed and position control with microcontrollers and motor drivers. Durable metal reducer: metal gearbox construction increases wear resistance and service life compared with plastic gears. Versatile voltage options: supports common DC voltages (6V / 12V / 24V) to fit a range of battery and supplypowered systems. This unit is the DC 6V variant. Compact Size 6 form factor: small footprint for spaceconstrained designs, suitable for hobby and light industrial applications. Product highlights Model/Brand: special motor Circuits DC Worm Gear electronic starter Gear ratio: 40:1 worm gear reduction Encoder: 11 PPR (pulses per revolution) built into the motor for feedback and closedloop control Material: metal reducer / gearbox Voltage options: 6V, 12V, 24V (this unit: DC 6V) Size: 6 (compact form factor) Application focus: torque gearmotor for smart control and toy engines Why customers choose this unit Makes small robots, smart toys, and mechatronics projects more reliable by combining torque, feedback and durability in a compact package. Solves common problems like gear slippage and poor holding torque thanks to the worm gear and metal reducer. Simplifies control and automation by including an encoder output suitable for interfacing with controllers, microcontrollers, and motor driver boards. Compatibility and integration Works with standard DC motor drivers and microcontrollers that accept encoder inputs; use appropriate driver and power ratings for the selected voltage (6V / 12V / 24V). Mechanical interface follows a compact Size 6 form factor—suitable for mounting in toys, small robots, and prototype assemblies where space is limited. Metal gearbox helps ensure reliable mechanical coupling and longer life under repeated start/stop and load conditions. Suggested use cases Smart toy engine: or upgrade toy drive systems to achieve stronger, smoother motion and add position feedback for automated behaviors. Small robotics and hobby projects: Use the 11 PPR encoder for closedloop speed or position control in wheeled robots, robotic arms, or pan/tilt mechanisms. Automated mechanisms and prototypes: Ideal for compact actuators, opening/closing mechanisms, or other small devices that require holding torque and feedback. What to expect in installation Confirm the system supply voltage (this unit is DC 6V) and select an appropriate motor driver that provides sufficient current and handles encoder signals. Secure the Size 6 motor to a compact mounting bracket or chassis; use proper coupling for the output shaft and avoid overloading beyond intended application limits. Connect encoder signals to your controller or counting circuit for speed/position monitoring; software or driver support may be required to interpret 11 PPR pulses. Materials and durability Metal reducer provides improved wear resistance and mechanical stability versus plastic gearboxes. Worm gear arrangement reduces backdriving and adds safety when holding position under load. Notes This listing corresponds to the DC 6V color/variant in Size 6. Other voltages (12V, 24V) are available in the product family. Ensure motor driver and power supply selection match your project's current and voltage requirements. A compact, torque solution with encoder feedback and a metal worm gearbox for projects that need reliable starting, holding, and precise control.
