Which engine to choose to rotate 1kg of weight?

Question

Arduino

looked at nema 17, but it's too powerful for this and
looked at this one, it's too weak ru.aliexpress.com/item/5V-4-phase-Stepper-Motor-Dr
... 1kg, it will need to be turned clockwise and counterclockwise, high speed is not needed, somewhere around 100 rpm will be enough, the axis of this platform will be directly connected to the motor (without gears, gears, etc.), or a 1: 1 gear is needed the simplest motor that can handle it, voltage up to 12v

Answer 1

Am I the only one who was jarred by "rotate 1 kg"? The engine has torque, speed, power, and so on and so forth, in the end, the service life, with the help of a gearbox, clutch and hydrostatic bearing, you can rotate at least a ton

Answer 2

You didn't specify a speed.
For even a rather weak engine can rotate your one kilogram using an appropriate gearbox. The question will already be in high speed / high torque.
Well, the type of engine, as I understand it, is it necessary to have a stepper? IMHO, for stupid rotation, it is also possible to connect the engine from the VAZ window lifter, already with the gearbox, and when it is stopped, it is difficult to turn. Cheap and cheerful. :)

Answer 3

At 100 rpm, you can forget about cheap steppers, or something like Nema (and it’s unlikely to be able to turn at such a speed), or less speed, or not turn with a stepper, but with an ordinary engine.
