Abstract
A three-phase motor forward and backward rotation execution module relates to an electronic switching module and is composed of electronic elements, a circuit substrate, and heat radiating fins. The electronic elements are installed on the circuit substrate to form an internal circuit. Thermosetting-type plastics are employed to package the internal circuit on the heat radiating fins to form a plastic packaging module.
