| Brushless DC motor controller designed in this paper is used for the limbs and torso humanoid robot motion, the working voltage of the motor is24V, the maximum working current is10A. Host PC for brushless DC motor controller via RS232communication issued by start and stop, speed control, steering and other control commands, brushless DC motor controller according to these commands corresponding operation on brushless DC motors. Hardware components:the microcontroller STC89C52, DAC chip TLC561, dedicated chip MC33035and six MOSFET tubes brushless DC motor controller is required to have control start and stop the motor, reversing and speed control functions. Software components:the use of assembly language programming, SCM and PC communications, control commands and data processing, sending control signals to the MC33035, brushless motor to achieve the various operations.Brushless DC motor as a new motor, it also has a common DC and AC asynchronous Click advantages, making it replace the old motor has become an inevitable trend of future development of the motor. In recent years, as the country’s economic and technological development of brushless DC motor production, quality and other aspects of the model and have achieved greatly improved. The face of the huge market demand at home and abroad, brushless DC motor has a wider application market. R&D cost stability for a wide range of brushless DC motor controller has a great application significance. |
