Sensorless field-oriented control (FOC) without current sampling for motorsAn apparatus includes a sensorless field-oriented control (FOC) motor controller. The motor controller includes a pulse width modulation (PWM) controller configured to generate PWM signals and to provide the PWM signals to an ...

Note: This board includes thephase current sampling ADCandmotor driveing, but does not include the AS5600 magnetic encoder, which needs to be installed on the motor. You need to prepare it additionally. Figure2: The schematic of my motor driver board, including AD7928 ADC. This board is op...

In this case, the common- mode voltage is close to zero and a low-cost shunt and an operational amplifier (op amp) can be used to sense the inverter current. The current sampling has to be done when the low-side switch is ON and the current sampling point must be synchronized with ...
Current sampling methods: Two ICS (only when running on STM32F103xx, STM32F2xx, or STM32F4xx); Single, common DC-link shunt resistor (ST patented); Three shunt resistors placed on the bottom of the three inverter legs (only when running on STM32F103xx, STM32F2xx, ...
* programs the resulting duty cycles in the related timer channels. It also sets the phase current * sampling point for the next PWM cycle accordingly. * * This function is used in the FOC frequency loop and needs to complete before the next PWM cycle starts ...

This delay ensures correct current sampling at the duty cycles close to 100 %. • ADC_ETC starts the ADC conversion. • When the ADC conversion is completed, the ADC_ETC ISR (ADC_ETC interrupt) is entered. The FOC calculation is done in this interrupt. User Guide MCUXpresso SDK Field...
