The Motor Control Daughter board is designed to work along side the Fusion Starter Kit. The board makes use of Fusion’s rich I/O features and flexibility to drive multiple motors on single platform. Fusion’s on-board PLL and clock generators target a wide range of motor frequencies. Internal threshold flags are used to control and protect the motor drive. Internal Real Time Counter can be used for logging applications and on-board nonvolatile memory to store important configuration data. Analog control is provided using internal ADC on Fusion.
主要特性:

方框图:
The average phase voltage is modulated using a PWM core to control the speed of the motor. A dedicated finite state machine is designed to commutate the motor both in Sensored and Sensorless modes. There are hardware controls provided through switches. An RS-232 serial interface engine is provided on-board and externally interfaces with the USB port through software.
