Small cylindrical AC synchronous motor with double flat shaft and wire leads

Unique-Bargains

Unique-Bargains Synchronous Motor AC 12V 0.9-1.1RPM 50-60Hz 4W Double Flat Shaft CW/CCW

SKU CH-ZVVT-SG7M7

A low-speed AC synchronous motor delivering 12 kgf·cm torque at 0.9–1.1 RPM for DIY and light-duty automation

  • Low-speed precision from 0.9-1.1 RPM synchronous operation
  • Stable speed regardless of load at rated 50-60 Hz frequency
  • Reversible CW/CCW rotation suits diverse automation needs
  • Compact 50 mm diameter body fits tight installations
  • 12 kgf·cm torque delivers strong holding force at low speed

AC synchronous motor for low-speed automation

The Unique-Bargains AC synchronous motor runs on 12 V at 50-60 Hz and delivers a rated speed of 0.9-1.1 RPM with 12 kgf.cm of torque. Its permanent-magnet rotor keeps speed stable regardless of voltage fluctuations, and the coil will not burn if the motor stalls or is overloaded. The 4 W power draw and low-noise operation suit continuous-duty appliances and hobby projects alike. A double flat shaft with CW/CCW rotation provides flexible mechanical coupling.

Sustained-load behaviour and thermal safety

At rated frequency the motor maintains its 0.9-1.1 RPM output without speed drift, even during extended runs in heaters, fans or popcorn machines. The integrated slowdown mechanism and permanent-magnet design prevent coil burnout when the load exceeds torque limits or the shaft stalls. Low power consumption and minimal acoustic signature allow uninterrupted operation in quiet environments such as massagers, lighting displays or science instruments.

7 mm double flat shaft with M3 thread

The 7 mm diameter shaft extends 15 mm and features a double flat plus an M3 threaded hole, enabling direct attachment of gears, cams or custom fixtures without adapters. Mounting uses 4.5 mm holes on a 50 mm body diameter, while 40 cm leads simplify wiring in tight enclosures. Builders needing a hollow shaft, keyway or different diameter must select another motor.

Questions about this item

How much heat or noise does the 4 W AC 12 V synchronous motor produce when running continuously?

The manufacturer describes the motor as low noise with small power consumption; at 4 W the heat output is minimal, and the coil will not burn even if the motor is overloaded or stalled.

What external items are required to operate this motor — power supply, mounting hardware, or couplings?

You need an AC 12 V source at 50-60 Hz, two wires for the 40 cm leads, and M3 screws for the 4.5 mm mounting holes; a coupling or gear must fit the 7 mm double-flat shaft.

Will the 0.9-1.1 RPM speed stay stable if I drive this motor from an older 50 Hz transformer instead of a modern 60 Hz supply?

Yes — at the rated frequency the synchronous speed is not affected by voltage and remains stable across the 50-60 Hz range.
