As someone asked you last time you posted, do you mean 3-phase motors or
stepper motors?  Three phase motors cannot hold a fixed position and are
used to drive machinery.  They usually run off three-phase mains
voltages and would need a relay, solid state or electromagnetic.
Stepper motors are used to drive a device from one fixed position to
another, and are usually controlled with transistors.  The cassette
recorder driver could be uprated with either a relay or a bigger power
transistor.
