Abstract

1306100 Measuring speed electrically ASSOCIATED ELECTRICAL INDUSTRIES Ltd 19 April 1971 [27 April 1970] 20127/70 Heading G1N An electromagnetic tachometer generator 4 feeding a load 9 and having an output whose amplitude and frequency depend on the speed of rotation is provided with a capacitor 10 which modifies its amplitude/speed characteristic, Fig.3, (not shown). The capacitor may be of such value as to provide a resonant turned circuit with the generator at a frequency equal to or just higher than that appropriate to the maximum desired speed of rotation. The generator may be of the multipole permanent magnetic type, Fig.1, (not shown).
