A linear electromagnetic driving device composed of multiple linear electromagnetic driving modules. A linear electromagnetic driving module has a base, an electromagnetic driving assembly, a crankshaft assembly and a bumper assembly. The electromagnetic driving assembly has a housing with coil and a linear magnetic shaft capable of moving linearly in the housing. The crankshaft assembly is mounted on the base, is connected to the linear magnetic shaft through crank arm and has two crank disks with pivot output shafts mounted rotatably on the base. The electromagnetic induced power output of each driving module is controlled and coordinated electronically through a sensor assembly on the driving device to maximize the energy efficiency.
