Abstract
A motorized assembly comprises first and second bridge circuits across which respective drive motors are connected. At least one auxiliary motor or actuator is connected between one arm of the first bridge circuit and one arm of the second bridge circuit and electronic control means are arranged to control the operation the drive motors and the or each auxiliary motor or actuator by operating electronic switches of the bridge circuits and an electronic switch connected in series with the or each auxiliary motor or actuator. Such an arrangement obviates the requirement for independent control circuitry for controlling the operation of the or each auxiliary motor or actuator, resulting in a reduction in the overall cost of the motorized assembly.
