    Bit of a hand waving explanation here, but in short...The the motor coils are rated for 2.1A, and you'll put them in parallel so 4.2A per motor. Due to them not drawing anywhere near full power most of the time, you can design for about 2/3rds of that, so 2/3*4.2*5=14A. 50V, so P=50*14=700W. So you need the nearest size transformer, or combination of transformers above that rating - so most likely 800VA. Plus some capacitors and a rectifier. I've currently got a 500VA and 325VA to power 5 or 6 of those motors.
