Unique-Bargains DC 12V 30RPM 8mmx14mm D-Shape Shaft Turbo Worm Geared Motor

SKU CH-YRPS-W7QAZ

DC 12V worm geared motor delivers 30RPM through an 8mm x 14mm D-shaft for bank equipment, safes, paper feeders, gas meters, tissue machines, automotive accessories, advertising gear.

  • 12 V DC operation powers low-speed automation tasks
  • 30 RPM output speed delivers high torque for precise motion control
  • 8 mm D-shape shaft provides secure anti-rotation coupling
  • Compact 31 x 57 mm gearbox fits tight mechanical enclosures
  • Two-pin terminal allows simple wiring in appliances and instruments

Application Scope

This DC 12V worm geared motor is designed for integration into equipment such as bank devices, safe boxes, paper feeders, intelligent gas meters, tissue machines, and automotive accessories. It also suits ad equipment, analysis instruments, and electronic game machines requiring low-speed, high-torque output.

Thermal and Power Characteristics

Operating at 12 volts with a two-pin connection, the motor body measures 31 by 57 millimetres. The worm gear arrangement inherently limits speed to 30 RPM, which reduces frictional heating and audible noise during normal operation, keeping power draw modest for continuous duty cycles.

Sustained Load Behaviour

The 8 by 14 millimetre D-shape shaft with a 3.4 millimetre female thread provides a secure mechanical coupling that resists slippage under constant torque. The all-metal gear construction maintains consistent output speed without thermal runaway, making it reliable for prolonged actuation in locks, shutters, and paper shredders.

Questions about this item

How do I mount the 31 x 57 mm motor body and connect the two pins without stripping the 3.4 mm female threads?

Bolt through the 31 mm diameter body using the 3.4 mm threaded holes, then solder leads to the two pins; the D-shape shaft flat must face the set-screw on your driven part to prevent slip.

Which part of the 30 RPM worm geared motor wears first and how do I replace it?

The internal worm gear mesh is the wear point; when backlash grows, swap the entire 12 V 30 RPM unit — no separate gear cassette is offered.

At what point does the 12 V 30 RPM motor hit its thermal limit during continuous duty?

The small 31 x 57 mm frame has no fan, so sustained full-load runs will hit winding temperature limits first; allow cool-down cycles or add external airflow.
