Cassette player motor rpm

[Seerox]

Hi!

Does anyone know the speed of regular cassette player motors. The tapes play with standard speed, so i guess the speed should be the same and constant. Is it so?

They mostly have pulleys with belts, that drive the tape. different players have different speed motors.

If you want to know the speed of the tape. Which is constant
