Motor Development Board
The motor development board is composed of two boards, MCU control board and power driven board. The two boards are connected by a 34-PIN IDC cable.
TC FOC motor control algorithm software, named ATC_FOC.rar. Unzip the RAR file , the software structure of FOC algorithm can be listed, mainly including the following parts:
(1) FOC_App:
a. Moduleinitialization
b. Get Hall state,calculate motor speed
c.PID initialization and PID controller
d. Phase currentsampling
e. ADC interrupt,execute FOC algorithm during ADC interrupt
(2) foc_control.lib
a. SVPWMimplementation
b. Clark/Parktransform implementation
c. Hall angleself-learning function
Module Initialization
Follow the detailed introduction in 《ATC_AC781x_FOC_Porting_Guide_CH.pdf》.
The motor development board supports the development and debug of the following types of motors:
Motor type | Control mode | Voltage range |
---|---|---|
BLDC- With Hall | Six step square control | 12~48V |
BLDC-Without Hall | Six step square control(using counter emf ) | 12~48V |
PMSM-With Hall | FOC | 12~48V |
PMSM-Without Hall | FOC + SMO | 12~48V |
