Embodiment Construction
[0026] attached Figure 5 The device is used to implement an improved method of voltage compensation. A switched reluctance motor 12 is shown for driving a load 19 . The voltage source 11 supplies power to the driver, which can be a DC power supply or a rectified AC power supply. The DC link is represented by a connection 10 and is switched via a switching device 13 to a phase winding 16 of a switched reluctance motor 12 on which a controller 14 determines the firing angle. Also included is a rotor position sensor 15 (RPT) responsive to an element that rotates with the rotor of switched reluctance motor 12 for generating a rotor position sensor output signal representative of rotor position. As can be seen, position information can be obtained by various methods, such as using software algorithms that estimate this information from the current, voltage and / or inductance of the motor. The current in the phase windings is measured by a conventional type current sensor 18 and ...
