... As described above, an alternator with the power vs. voltage curves of Fig. 5 is well suited to an output voltage of 14 V, but is not suitable for a higher voltage such as 42 V. If one wanted to operate at 42 V, one could rewind the stator with three times as many turns of wire having a third the cr ...

... (a) If the power system is exactly as described above in Figure (a), what will the voltage at the load be? What will the transmission line losses be? (b) Suppose a 1:10 step-up transformer is placed at the generator end of the transmission line and a 10:1 step-down transformer is placed at the load ...

Application Note TLE8110EE
... Unipolar or bipolar drive - see Figure 1: Bipolar drive requires two H-bridges for driving, but uses the full amount of copper windings, so the motor delivers more torque. Unipolar drive only uses half of the winding, but only requires four low-side switches. ...

步进电机的物理原理
... Stepping motors can be viewed as electric motors without commutators. Typically, all windings in the motor are part of the stator, and the rotor is either a permanent magnet or, in the case of variable reluctance motors, a toothed block of some magnetically soft material. All of the commutation must ...
