overcompounding1892
1892 S. P. Thompson Dynamo-electr. Machinery (ed. 4) xi. 295 The same process suits for over-compounding, the excitation at full load being raised until the volts at terminals rise to the higher number of volts that will allow for the drop in the leads.
1938 A. E. Clayton Performance & Design Direct Current Machines (ed. 2) 416 A diverter was used on site to adjust the degree of over-compounding to suit the local conditions.
1966 J. Meisel Princ. Electromech.-energy Conversion ix. 394 By a slight overcompounding the droop can be taken into account and the output voltage at no load..can be made equal to the output voltage at full-load current.
1997 Illustr. Dict. Electronics (ed. 7) 497/1 Overcompounding, a characteristic of electro mechanical motors, resulting in increased running speed with decreasing load resistance.
