I'm trying to mod my Tascam cassette recorder. I want to be able control speed of the motor.
So I bought on ebay PWM controller and after installation thing don't run so smooth as I wish.
the problem is ... when pot is all the way down at 7 clock motor is off, when I turn it to 8 a clock motor starts spinning and reaches its full speed at 9 a clock. and from 9 a clock to 4 there is no effect on speed.

Your not using the right controller for that motor. That is a basic DC motor. You don't need PWM you need variable voltage.

Isn't true that if I lower voltage current will go up and burn out the motor ?
