4.3
BLDC motor rotation control by the microcontroller
This section describes how the BLDC motor is practically controlled with the 120° conduction method by
the microcontroller.
On the board, as shown in “ Figure 4-4 Motor driver circuit ”, the micro controller is connected with the
motor driver circuit. The relationship of the connections with the semiconductor elements described in
4.2 How does the BLDC motor rotate? ” is as shown in Table 4-1 Microcontroller pin/Motor driver
circuit connections ”. By turning RTO0 to 5 on/off according to the positions of the hall elements as
shown in “ Figure 4-3 120° conduction method time chart ”, the motor can be rotated.
