- Save months of design time with nearly fully automated identification and control tuning, allowing designers to differentiate their products with capabilities beyond full motor torque.
- Near encoder performance with embedded on-chip FAST observer algorithm calculating a reliable and robust estimation of flux, angle, speed and torque across use conditions. Accurate, sensorless "estimator" performance eliminates the need for a physical encoder in most cases.
- A ccommodate all three-phase motors, synchronous (BLDC, SPM and IPM) and asynchronous (ACI) with the same solution.
- Identify and tune with off-line motor commissioning that identifies the needed electrical parameters of the motor, tunes the FAST algorithm, and initializes the current controllers for stable operation. An optional online resistance re-estimation mode which tracks changes for robust observer performance in the harshest use cases is also offered.
- Eliminate start-up challenges of other sensorless techniques with built-in start-up modes and observer angle lock in less than one electrical cycle.
- Slow speed performance with angle integrity preserved at steady state below 1 Hz (typical) with full torque, reversals through zero speed and stall conditions with smooth stall recovery.
- Gain flexibility with the ability to implement a single function call FOC torque controller (supports up to two motors from the same ROM) or a completely custom control system with FAST as the motor sensor.
- Allow most efficient motor sizing with built-in field control, providing manual or automated field-weakening (higher speeds) or manual field-boosting (higher torque) applications.
- Gain massive energy savings for induction motors using the PowerWarp™ mode, eliminating energy waste during times when torque is not immediately required.
- Develop easily and evaluate quickly using the new motor control library (modules, drivers, system examples, documentation) through MotorWare™, which offers latest in C object-oriented and API-based coding techniques. Conduct lab instrumentation through TI's free, new GUI Composer tool.
