MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202641076419 A) filed by Chaitanya Bharathi Institute Of Technology on June 19, 2026, for Modular Double Stator Single Rotor Axial Flux Permanent Magnet Machine With Adaptive Airgap Control.
Inventors include Umakanta Choudhury; and Gayathri Madrekar.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: A modular axial flux permanent magnet machine is disclosed. The machine comprises a double stator single rotor configuration including a rotor disc carrying permanent magnets on opposing faces and stator assemblies positioned on opposite sides of the rotor disc. An adaptive airgap control mechanism is configured to maintain predetermined airgaps between the rotor assembly and the stator assemblies to compensate for thermal expansion, mechanical deformation, manufacturing tolerances, and operational loading conditions. The machine further incorporates an optimized electromagnetic configuration including fractional-slot concentrated windings and coordinated selection of airgap dimensions, stator geometry, and magnet parameters to improve torque density, efficiency, magnetic flux utilization, and operational stability while reducing cogging torque and torque ripple. A modular architecture enables multiple machine units to be stacked along a common shaft to provide scalable power and torque output for direct-drive power generation and electric drive applications.
