Abstract

This article proposes and implements a frequency-modulated wireless direct-drive motor control (WDMC) for a promising application of underground in-pipe pumping. Accordingly, a novel urban drainage scheme is conceived, which offers high robustness, mobility, and flexibility. This scheme can help with the emergency response to prevent severe weather hazards, such as heavy rainfall. To power one energy-demanding unit of pumping network, a movable energy-carrying electric vehicle can park above the underground in-pipe pump and wirelessly drive the motor for accelerating the flow rate as required. Also, a pulse frequency modulation is newly used for wireless motor speed control with frequency-reduced zero-voltage switching. The system efficiencies can reach 87.6% and 83.9% with two tested power levels of 430 W at rated load and around 600 W at overload, respectively. Theoretical analysis, computer simulation, and practical experimentation are given to verify the feasibility of the proposed drainage system using the frequency-modulated WDMC.
