I wanted to use bgm5208-75 to build a 2-axis gimbal. To control the motors what I could use?
A motor driver chip and a lot of mathematics.
Do you have a datasheet for the motor? That will show the amps and volts required to select a driver.
Gimbal motors need an active control loop to work, its quite complicated to do you own unless you
are confident with feedback control loops and 3-phase sinusoidal motor drive techniques...
