Kinetis motor control appropriate for micro pump?

I'm an EE undergraduate student, recently assigned to a research team designing a pump for liquid CPU cooler. The pump impeller is approximately 2 inches (50 mm) in diameter and has slots for permanent magnets, and will act as the rotor of a BLDC motor, seated in a stator with coils. Attached is a picture of a prototype rotor, where you can see slots for six magnets.


I'm trying to find a suitable motor controller to test our pump design. The motor will likely be putting out less than 1.5 W of power. Are any of the Kinetis series motor control MCUs appropriate for this purpose?
