AN4013

Specific applications

Configuring the timer to generate a six step signal to control a brush-less 3-

phase DC motor (3-phase BLDC motor):



Time base configuration: prescaler, period, clock source



Channels 1, 2, 3 and 4 configured in PWM mode



Set the capture compare preload control bit CCPC



Enable the commutation interrupt source



Use the system tick to generate time base



Each commutation event, the TIM configuration is updated for the next commutation

event.

For more details on using the timer in this mode, refer to the examples provided in the

STM32xx standard peripheral libraries, in the /Project/STM32xx_StdPeriph_Examples/

TIM/6Steps folder.

Note:

This example is not available for STM32L1 series.
