Motor to driver

If I have a 90 v.d.c servo motor and a servo driver that goes from 10 v.d.c to 75 v.d.c. Could they be used together?

If the 10VDC to 75VDC is the servo drives power supply range
and the servo drive can supply enough current for your motor
and the servo drive is designed as a DC motor drive

Then yes, it should work. The 75V limit just means that you can
only reach 75/90 (83%) of the rated maximum motor speed

So the power supply should not exceed the servo drive of 75 volts d.c.? Match the drive and power supply and not the motor?

Yes! Exceeding the drivers voltage rating will likely destroy the driver.
