Hello. Thank you your answer’s. Your answer’s helps.
My task is to provide high-repeatability precision keeping one instantaneous speed = 3000 ob/min brushless DC motor; on shaft of motor is big moment of inertia for smoothing rippling of speed; load is ventilation; brushless DC motor Maxon 118889(no-load speed 11000 ob/min, number of pair poles = 2); acceleration is smooth (1minute – 3000 ob/min); brake action is running-out; reverse is not necessary. Is it possible on DRV8308? Is it possible to check on Kits DRV8308EVM? What system is it do (open-loop or close-loop)? What mode task of speed is use (open-loop PWM, close-loop, speed register)? If this task doesn’t solve on DRV8308, recommend your microchip which to solve this task.
