SMALL FPGA BASE-DIGITAL TYPE MOTOR CONTROLLER, DESIGN STRUCTURE, AND PROVIDING METHOD THEREOF

摘要

PPROBLEM TO BE SOLVED: To provide a motor controller 102 not dependent on software. PSOLUTION: The small FPGA base-digital type motor controller 102 includes a sensor interface 206 that is configured to receive sensor data from one or more sensors 104 for providing position information of a DC brushless motor 108 and to generate sensor data after adjustment, a commutation controller 210 that is configured to generate a switching command for controlling commutation of a DC brushless motor 108 and that generates a commutation pulse from the sensor data after adjustment from the sensor interface 206, and a time inverter 208 that is configured to receive a commutation pulse from the commutation controller 210 and convert the commutation pulse into a rotational speed of the DC brushless motor 108 for providing a linear feedback control parameter.
