ST offers AEC-qualified integrated chipset for up to 48V electric BLDC traction ECU (Electronic Control Unit). Each component has its own development toolchain and set of collaterals; a complete motor demonstrator based on this chipset equipped with a FOC control library is also available.
The software package includes:
- The SPC5-MCTK-LIB motor control library, capable to drive single or dual Field Oriented Control (FOC) 3-phase Permanent Magnet motors;
- A helpful plug-in configurator fully integrated into SPC5Studio Open Development Environment that helps and guide user to fine-tune the motor performance;
- SPC5 Motor Control Live Monitor to visually check and control the motor.
The key building blocks of ST proposal are MCU from 32-bit Power Architecture family, L9907 BLDC predriver and 100V MOSFETs for bridge inverter implementation. Particularly suitable for motor control applications, the SPC560P includes specific peripherals such as six channels PWM outputs (flexPWM) which can be used to control each single phase of a 3 Phase BLDC motor, two ADC whose shared signal can acquire the three phase current and a Cross Timer Unit (CTU) to completely avoid CPU involvement for in-time acquisitions of the state variables during control cycle (PWM cycle, half PWM cycle or number of PWM cycles).
