Need a super slow, reliable motor for a project? This little AC synchronous gear motor is perfect. It runs on standard 220-240V household power at 50/60Hz and only uses 4 watts, so it's pretty efficient. The cool part is its speed – you can choose a really slow output like 0.8 to 1 revolution per minute (RPM), which is ideal for things that need to turn very gently. Other speed options are available too (2.5-3, 5-6, or 8-10 RPM). It's got decent torque for its size (14 kgf.cm at the slowest speed). The motor has a built-in self-protection feature, so if it gets overloaded or stalls, it won't burn out the coil – a big plus for longevity. It's a combination of a permanent magnet motor and a reduction gearbox (with metal and plastic gears) that runs quietly. Weighs about 90g and is quite compact. People use these for all sorts of stuff: rotating displays, fan oscillation mechanisms, heaters, slow-moving Christmas decorations, lamp rotators, toy mechanisms, even in some appliances like microwave plate motors or air conditioners. A versatile little workhorse for DIY and repair.
