AC 12 V synchronous motor for low-speed projects

This new AC synchronous motor runs on 12 V at 50 to 60 Hz and delivers 4 to 5 RPM with 6 kgf·cm of torque. It is suited for hobbyists and engineers building slow-motion mechanisms such as display turntables, timer drives or educational models. The bidirectional CW/CCW operation allows reversible rotation without extra gearing.

6 kgf·cm torque at 4 to 5 RPM defines the load limit

The single figure that decides fit is the rated torque of 6 kgf·cm at the rated speed of 4 to 5 RPM. If the driven load exceeds this torque the motor will stall, though the supplier notes the coil will not burn under stall conditions. Voltage and frequency stability keep the speed constant regardless of normal supply variation.

7 mm double-flat shaft fits M3 mounting

The 7 mm diameter shaft is 15 mm long with a double-flat profile and an M3 threaded hole for secure coupling to gears, cams or custom arms. The motor body measures 50 mm in diameter, 20 mm high and 65 mm total length with 4.5 mm mounting holes. A 40 cm lead wire provides connection length for panel or chassis wiring.

Highlights

  • Low power draw with 4W AC 12V operation
  • Stable 4-5RPM speed at 50-60Hz frequency
  • Reversible CW/CCW rotation for flexible mounting
  • Compact 50mm diameter body fits tight spaces
  • 6kgf.cm torque handles light mechanical loads

Questions about this item

What does the 4-5 RPM speed mean when the motor is running in a device?

At 50-60 Hz the motor locks to the mains frequency, so its output shaft turns at a steady 4-5 RPM regardless of load until it stalls.

How does the AC 12 V 50-60 Hz supply limit the motor's performance?

The motor only reaches its rated 4-5 RPM and 6 kgf·cm torque when fed 12 V AC at 50-60 Hz; voltage changes do not alter speed, but the coil will not burn if stalled.

What mounting holes and shaft dimensions are needed to fit this motor?

The body is 50 mm diameter with 4.5 mm mounting holes, and the 7 mm shaft extends 15 mm with an M3 threaded centre hole.
