finding a High voltage BLDC motor with trapezoidal Back-EMF.

[samy56]

Hi, 

I have a big problem finding a High voltage BLDC motor with trapezoidal Back-EMF. Most the available motors have sinusoidal back-EMF. 

I have this problem also with low-voltage BLDC where Manufacturers Dont mention the shape or construction details of their motor, so the only way to make sure is to buy the motor and check the Back EMF.

Hello,

This is very simple. Any micro with PWM can handle your requirements.

You only need to generate PWM and measure the BEMF.

have a look for example on S32K1 micro, it is cheap and good for such purpose.

Best regards,

I want to explore nxp trapezoidal controllers with a motor with trapezoidal bac-EMF. But i couldn't find any
