Silver cylindrical DC worm gear motor with encoder board and multicolour cable loom

Unique-Bargains

Unique-Bargains DC 12V 111RPM 4Kg.cm Worm Gear Motor With Encoder And Cable

SKU CH-SMBE-FQ03T

A 12 V DC worm gear motor delivering 111 rpm and 4 kg·cm torque with a built-in encoder and 20 cm cable

  • Self-locking worm gear holds position without power
  • 111 rpm output speed at 12 V DC supply
  • 4 kg·cm torque for high-force applications
  • Integrated encoder provides closed-loop speed feedback
  • 20 cm colour-coded cable simplifies wiring

DC 12V Worm Gear Motor With Encoder

The Unique-Bargains DC 12V worm gear motor delivers 111 RPM no-load speed with a 1:36 reduction ratio and 4 Kg.cm torque. It features an integrated encoder and 20 cm cable for position feedback in automation projects. The self-locking worm drive holds position when power is removed. The 8 mm D-type output shaft measures 15 mm in length.

Encoder Wiring Constraints And Voltage Limits

The encoder requires a separate 3.3 V to 5 V supply on the blue and black wires; reversing this supply will damage the device. Yellow and green signal wires must never connect to any power source or they will burn out. Motor direction is controlled by swapping the red and white motor supply wires. These strict wiring rules limit use to builders who can provide dual isolated voltage rails.

Upgrade From Basic Gear Motors Without Feedback

This unit replaces simple DC gear motors that lack position sensing, adding closed-loop capability for robotics or linear actuators. The jump is worth it when an application needs to verify shaft position or maintain hold without continuous power. It does not suit buyers who need higher speed, greater torque, or a hollow shaft for cable routing.

Questions about this item

Should I choose the 12V version or a different voltage for my project?

This motor is supplied only in a 12V DC configuration, so select it when your control system provides a 12V supply.

What does the 111RPM no-load speed mean once the motor is installed in my machine?

At 12V with no load the output shaft turns at 111RPM; under load the speed will drop depending on the torque required.

How does the encoder interface work and what voltage does it need?

The encoder requires a separate 3.3-5V supply on the blue and black wires and outputs speed pulses on the yellow and green wires.
