A universal motor is a series-wound electric motor that can operate on both AC and DC power. These are a lot compared to those of DC series motors but the series motor develops less torque when working from an AC supply than when working from an equivalent DC supply. The direction of ro...
3.3 Load attenuation The load block is composed by the equivalent circuit of the motor winding (resistance and inductance) plus the sense resistor. We will considered the effect of the Bemf voltage of the motor in the next chapter. The input of this block is the PWM voltage of the power ...

Drive's converter circuit is designed in such a way to realize all the standards of input power system. Based on the signals frominput voltage divider, converter generates a constant DC bus voltage to drive the Brushless DC motor. Drive's inverter designed with SPWM instead of square PWM, ...
universal in the sense that it is derived by extending the low frequency standard-T-equivalent circuit (IEEE Std. 112) to include high-frequency effects under both common-mode and differential-mode domains, and can be used for transient reflected wave studies and EMI emissions in motor drive ...
