Sensorless motor drive is PMSM or BLDC controller designed for the oil and gas industry based on a single microcontroller architecture. It withstands various harsh environments while providing high reliability for applications with no accurate position sensing need.
Drive design workflow
The drive design follows a specific model-based design workflow:
1. Design: design of the drive with respect to specifications.
2. Simulation: simulation models are built for the designed drive and its control.
3. Code Generation: an embedded code is automatically generated from simulation model. 4. Test and validation on target
5. Compliance verification : if the design features do not meet the specifications, issues are addressed by checking and updating the simulation model and/or the design. The workflow steps will be repeated until the design becomes compliant with the specifications.
6. Delivery
The components lever to efficiency
The control strategy is based on a sensorless six-step control. The driver can handle high temperature conditions (up to 175 °C) and it is designed for a permanent application. The components involved in the design are restrained to customers approved components. The microcontroller requires only 3.3 V power supply with a very low power consumption (within 250 mW) and it has various communication modes: I2C, SPI, USB and USART/UART. The control part is compact and can fit in 35 mm x 100 mm area.
