Infineon Motor Inverter with Block Commutation Algorithm
The Crevavi IOT design team has successfully prototyped The Infineon 48V, 10KW Motor Inverter with Block Commutation Algorithm. This is a demonstration project for driving BLDC motor using motor inverter with block commutation algorithm, designed to power high performance motor with unparalleled efficiency. The Block diagram of the designed Infineon 48V, 10KW Motor Inverter is illustrated in the figure.
Block commutation is a method that controls the timing of a power supply to the motor’s coil, which is essential for BLDC motor. It enables smoother operation and precise speed control by adjusting the potentiometer, we can seamlessly control the motor’s speed, demonstrating the system responsiveness and versatility.
Hardware connection includes 48V DC power supply, Infineon inverter, output terminal of the inverter labelled U, V and W are connected to the corresponding terminals of the motor.
A variable potentiometer and Hall sensor signal are used for accurate feedback from the motor, and they are connected back to the inverter.
A 12v DC supply and digital storage oscilloscope are used to power up and display the Hall sensor signals A, B and Z in real time, allowing us to monitor the motor’s performance closely.
Thus, with the aid of the block commutation algorithm, the motor initiates its operation smoothly, utilizing Hall sensor feedback to ensure precise control.
