SENSORED VECTOR CONTROL THREE PHASE MOTOR DRIVER DESIGN BASED ON CORTEX M7 ARM

Three-phase brushless motors are an indispensable part of the industry. A significant portion of electricity consumption is the energy consumed by industrial motors. Therefore, these electric motors need to be used efficiently. If these motors are not driven by the suitable inverter, they cannot handle the load or increase losses in the energy. In addition, the system can be inefficient. Since these motors have a high starting torque and controlling rotation speed is difficult, a better control method is preferred rather than a V/f control. This research aims to control using PMSM (permanent synchronous motor) FOC method and Space vector PWM with the position sensor, which is incremental encoder and. FOC approach, will minimize energy losses. Also, Space vector PWM method reduces the harmonic of the motor current. The FOC approach is to direct the stator rotating field most efficiently using the motor's rotor position information. The incremental encoder will provide the information rotor position and speed. The software structure is achieved through the utilization of a STM32F745VE that is new series Cortex™-M7 32 bit ARM® processor. FOC calculation takes 14.5 microseconds thanks to the Cortex M7 architecture and floating point unit.
