Why is my 'synchronous' motor running fast?
I bought a synchronous motor as a replacement motor for a flip clock, as they no longer make the same model that was used in the clock. The motor in the clock originally was a synchronous motor at 110 ...

Why is SVPWM preferred over min–max PWM if they are mathematically equivalent?
Space Vector PWM (SVPWM) and min–max (zero-sequence injection) PWM are mathematically equivalent and produce identical duty cycles. Despite this, SVPWM is widely used in practical FOC implementations.
