drive board for three-phase brushless motor using three hall sensors (pre-driver bm64300muv)
evaluation board to drive a 3 hall sensor three phase brushless dc motor with supply voltage of 48v (typ) and motor current of 8a (max) . it consists of a 3 hole sensor three phase brushless dc motor pre-driver and 6 nch mosfets. the rotor position is detected by 3 hole sensors, and the sin wave drive realizes silent and low vibration, and the automatic advance angle control enables highly efficient motor drive. the output mosfet can be mounted in the to252 package or the hsop8 package. in this board, the to252 package product is mounted.
