The invention discloses a multifunctional power mechanism including a lead wheel, a magnetic housing, a central shaft, a system inverter and at least one bearing. A shaft hole is arranged in the center of the lead wheel. An inner coil unit is annularly arranged on a wheel face a proper distance away from the shaft hole. The tail end of the whole inner coil unit is connected with the system inverter. An outer coil unit is annularly arranged on a wheel rim. The lead wheel is arranged in the magnetic housing in a wrapping manner and the lead wheel and the magnetic housing are not in mutual contact. The center of a housing face of each end of the magnetic housing is provided with a bearing pipe. At least one bearing pipe sleeves the bearing. Therefore, power generation of the inner coil unit can be driven magnetically since power is transmitted to the outer coil unit of a first-stage multifunctional power mechanism after the bearing pipes are connected with each other or one bearing pipe is connected to another multifunctional power mechanism via an external transmission mechanism, the generated power is sent to the outer coil unit of a next-stage multifunctional power mechanism via the system inverter, and then power is generated for utilization through inductance motion stage by stage. Also, power can be transmitted to the outer coil unit and the inner coil unit, so that an electric motor having larger power is realized and a multifunctional power selection effect is achieved.
