for vending machine project based on esp32.
servo that strong enough to move spiral and compatible with esp32.
Why a servo?
I think a simple geared DC motor would be simpler and cheaper.

truth be told i am asking for a friend
i actually suggested d.c, seems more right for the job.
but my understanding is its an assignment.
he tried the mg90s, but says he cant control direction.
You only need to rotate a vending machine spiral one way, never backwards.
So actually what does he want to do?
Even if you do need to move both ways, you will need a continuous rotating servo. Regular servos are limited to 0 to 180 degree movement and could not rotate the spiral.
You control it using the Arduino servo library.
I don't know the torque reguired to turn the spiral so can't recommend a servo offhand
Also, most servos require a 5V control signal but some will operate with 3.3V signals.
Feetech FB5311M-360 has a stall torque of 15kg-cm and will work with 3.3V input signals.
It also has a feedback signal. You will need a power supply of at least 2A and a voltage between 4.8V and 6V. A 2A, 5V supply should work.
thanks
i will forward that.
