Have you looked at Hobby grade (airplanes, helicopters) Brushless motors? They are three phase, and use sensorless commutation, so only three wires running to the motor. The hobby three phase motor controllers are easy to command, most if not all run off PWM. And all the parts are cheap. Just a consideration, don't know if they will fit what you need.
What rotational speeds do you require? And for what purpose?Every brushless motor speed controller you could shake a stick at:http://www3.towerhobbies.com/cgi-bin/wti0095p?FVPROFIL=&FVSEARCH=BRUSHLESS+MOTOR+esc&search=Go
Never used them but have skimmer data sheets and app notes.Allegro has drive chips and app notes at:http://www.allegromicro.com/en/Products/Categories/ICs/motor.aspMicrochip also has some app notes:http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1469A little additional searching of motor drive chips and apps will get you some more info.
400+mNm of stall torque[...]but i don't know the stall current(it's not in the datasheet,
Or should i look for different controller with DIP package?
