Hi im new to forums and new to electronics

im making a record player and i have a problem with controling the speed of the motor its a 6V running off a 1.5v power source

how can i make the motor spin slower but can still use the same voltage
i have other things that needs at least 1.5v

 

If it is a low power motor use a resistor in series with it. However, if it is a high power motor use PWM to control the average voltage across the motor and thus its speed.

 

im not sure if its low power or high power


it spins really fast on full power

would a potentiometer or some kind of hand control be used

i want to be able to control it by hand too

im soory i didnt say that before

 

Use a belt speed reduction. A small pulley on the motor's shaft and a belt that goes around the record platter.

The motor pulley should have a high spot in the middle; aka convex. That will keep a flat belt tracking in the middle of the pulley.

You will need to use controls such as a phase lock loop in order to keep the platter rotation speed steady. If you don't, you will have very noticeable "wow" and/or "flutter".

A heavy, well-balanced platter on really good bearings will help to minimize the wow/flutter. A flywheel on the motor will also help a great deal to keep the speed constant.

 

thanks so much
