Marius, the spindle motor in question is going to be a beast , as it's really a servo motor and Tacho , and may well have brake also these tend to crazy to work with , as you'll also need to be able to not only hold positon and zero crossing switches etc you need to monitor each leg and phase . amongst others to do it correctly
it will also depend to a point on the type of winding used on the dc motor . as Andy suggests chat with Jon Peter or JMK . or find a Kolmorgen servo drive and Line Balancer , as thats quite a beefy load to toast .
