At an exam, I was asked the following question: A stepper motor has the greatest torque on its shaft in the 'halfstep/full step'. Everywhere on the internet it says that full step gives the most torque. This was also the answer I indicated. I have already emailed this to my professor but he claims that: at half step 2 coils are energised, which gives a field that is the vectorial sum of the two separate fields. Therefore, this field is stronger than the field of 1 coil. Is this correct? Does anyone know how I can prove him wrong? Thanks in advance
