where [omega] denotes the angular velocity of motor and [C.sub.e] is the back electromotive force constant.
Figure 4 shows the no-load back electromotive force (EMF) waveforms when rotating at 1000 rpm, the number of conductors in each coil is chosen to be 1 for both machines.
The back electromotive force (EMF) is too small in the low speed, which is crucial to estimate.
A growing number of applications, however, are now eliminating the sensor through one of several methods, such as back electromotive force (EMF) or inductance measurement.
