I am going to control three piezomotors.
The motors never have to move at the same time so I was thinking about the possibility to let the motors share one TMCM-090 driver because there is a very limited space in this application and there is not room for 3 drivers.
I was thinking of use 12 small solid-state relays between the motors and the driver, (one for each phase) and choose which motor that should be connected at a certain time with help of the relays, controlled by my microcontroller. I would only need to switch when the motor already have stopped.
Can i to this with the TMCM-090?
