In this paper, a transmitter-side control method is proposed in inductive wireless power transfer (I-WPT) model for the speed and power control of a single-phase induction motor (SPIM). Resonant tanks with an electronic driving mechanism are used in the proposed configuration. The receiver side employs two resonant circuits with two full wave rectifiers, comparator, and two gate drivers for the management of the motor speed and power. The resonant circuits and electronic motor drive are presented through detailing the mathematical model and system design. In addition, a comparative section of the proposed model with the previous art is introduced to address the contributions of the paper. Moreover, a prototype model of the proposed topology has been created in simulation environment and tested in a variety of scenarios. The proposed I-WPT model has a power rating of 140 W, whereas the SPIM has a power rating of 120 W. At full power operation, a 130 W power is supplied from the source during 118 W power consumption of SPIM, indicating that the system's efficiency is over 90%. The motor speed control has been tested by lowering the operation frequency of the motor terminal voltage from 60 to 40 Hz and from 40 to 20 Hz. The dynamic motor power has been also analyzed by reducing the load power from 100% to 70%. The findings reveal that the proposed transmitter-side controlled I-WPT system operates in a wide range of circumstances.
