Need help with Power Supply for 12V 4watt Motor - Circuits and Projects https://forum.etechnophiles.com/basic-electronics-circuits-projects/need-help-with-power-supply-for-12v-4watt-motor/ Hi, Welcome to the eTechnophiles forum. Got a question like, \'What resistor value to choose for your simple LED project\' OR \'Where is the resistor connected to the inbuilt LED in Arduino UNO\'s schematic\' - All will be answered here. Feel free to check out the topics below. en-US Sun, 13 Sep 2026 02:03:51 +0000 wpForo 60 Answer to: Need help with Power Supply for 12V 4watt Motor https://forum.etechnophiles.com/basic-electronics-circuits-projects/need-help-with-power-supply-for-12v-4watt-motor/#post-251 Sun, 08 Dec 2024 15:34:15 +0000 This motor, as described on the product page, is an AC gear motor. Therefore, it is designed to be powered by alternating current (AC).

The confusion might arise because 12V is mentioned, which is more commonly associated with DC systems. However, in this case, the motor is specifically designed to operate with 12V AC input. This means it requires a 12V alternating current power source, not direct current (DC).

If you will watch the video given on the product page, you will see that they used a transformer(surely a 12V step-down) without a rectifier or similar circuit. 

In conclusion, you need a 12V step-down transformer to convert your outlet(220V or 110V depending on your location) voltage to suitable voltage for the motor to run.

I just bought a synchronous motor and need to power it. The motor is 12 volt AC 4 watt 50Hz. Can someone point me to what outlet and inverter (if necessary) is needed to power this motor, whether it be an outlet or battery powered? Here is a link to the motor I am using.

Thank you for any help you can provide!
