    issue with homemade DC motor + hall effect sensor

    Is the orientation of the magnets (north / south) correct? Is the polarity of the coils correct (is one of the coils the wrong way around)? Did you try to hold the hallsensor the other way around? Bertus

    issue with homemade DC motor + hall effect sensor

    Could there be a problem with the mosfet. It has a gate voltage threshold of 2 to 4 volts. An irlz44 has a threshold voltage of 1 to 2 volts. Bertus
