Start spinning in seconds with InstaSPIN™-BLDC

Targeted at low-cost BLDC applications, InstaSPIN-BLDC is a sensorless control technique that can get motors up and running in seconds and doesn't require any knowledge about motor parameters to work with only a single tuning value. Unlike other sensorless BLDC control techniques based on back-EMF zero-cross timing, InstaSPIN-BLDC monitors the motor's flux to determine when to commutate the motor. With the help of a free GUI, the user can watch the flux signal in a plot window, and set the "Flux Threshold" slider to specify at what flux level the motor should be commutated. Optimal commutation can be verified by observing the phase voltage and current waveforms, which are also displayed.

Using flux for commutation vs. back-EMF zero-cross timing also enables more stable operation at lower speeds. Unlike the flux signal, the back-EMF signal amplitude diminishes at lower speeds, resulting in poor signal-to-noise performance. InstaSPIN-BLDC enables smoother operation at low speeds, and provides more reliable motor starting, even under heavy loads.
