Abstract
Device for energizing a number of coils of a hook selection device for a weaving machine includes an electrical power supply source connected to the coils and a regulating device for regulating the current intensity in the coils. Each coil includes: a comparator for comparing the current intensity in the coil to a reference current intensity and a controllable current regulator (e.g. a chopper transistor) for regulating the current intensity in the coil in order to reach or approach the reference current intensity. The regulating device includes an electronic control circuit that is provided to control the current regulator of each coil of a number of coils, in order to reduce a variance between the actual current intensity in that coil and the reference current intensity measured by the comparator of that coil.
