Is there any risk if I use the instaSpin-foc Driving BLDC motor？

No problem, InstaSPIN-FOC can support PMSM, BLDC and ACIM, that runs BLDC as PMSM using sensorless sinusoidal FOC.

Download motorWare as the following link that includes example lab projects and documentation for instaSPIN-FOC.

Thanks.

If drivering the BLDC use the InstaSPIN-FOC，the phase current of BLDC will also be sinusoidal signal？ or Square wave signal？ Because I find that the phase current of my motor（BLDC）is distorted(not sinusoidal signal,nor Square wave signal),you may refer to the figure。Will the phase current showed in the picture deteriorate the FAST？

As replied in a similar thread you posted. InstaSPIN-FOC follows BEMF shape to control the current output, the pure sinusoidal or trapezoidal/square shape of the current signal is just shown in an ideal case. For a real case, the current waveform depends on motor specifications ( like BEMF waveform) and sampling signal quality of current/voltage.

Thanks.
Will the current waveform influence the angle estimation? How to estimate the quality of the feedback current waveform? Are there any standards to evaluate the quality of he feedback current waveform?

1. No.
2. Please refer to lab01b and lab01c.
3. Not a critical standard, it should be an engineering topic, more clear much better.
