Abstract
A bidirectional motor has two electromagnetic contactors, one for forward, the other for reverse operation. Thermal protection is provided by a thermal image generator and a thermal protection unit in each contactor operating in tandem via a bidirectional line of communication keeping the thermal images in parallelism by one active contactor 'talking' to the inactive contactor, the 'listener'.
