The InstaSPIN-FOC field oriented control option for the 90 MHz TMS320F28069 microcontroller allows designers to identify, tune and control through variable speeds and loads any type of three-phase, synchronous, or asynchronous motor in five minutes or less. The design tool uses a software encoder algorithm called FAST embedded in the MCUs ROM.
The algorithm will yield angle lock in less than one electrical cycle during motor start-up and low speed performance provides angle integrity preservation at steady state below 1 Hz (typical) with full torque. System features allow efficient motor sizing with manual or automated field-weakening (higher speeds) or manual field-boosting (higher torque) and provide significant energy savings. (FAST MCU option on TMS320F2806xF microcontrollers – available now.)
