MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202521131803 A) filed by Proheartz Electic Llp, Pune, Maharashtra, on Dec. 25, 2025, for 'a brushless inductor-type alternator.'
Inventor(s) include Arun Ramkrishna Limaye.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "A brushless inductor-type alternator comprises a stator (3) carrying three-phase star-connected armature windings (4), a rotor (2) consisting of two ferromagnetic claw poles without windings or permanent magnets, a completely stationary shaft (1) having a fixed shaft portion locked to the rear end head (6) and a drive shaft portion assembled in the front drive end head (5), and a stationary excitation field coil (7) directly wound on a flanged core without a separate bobbin and rigidly mounted on the fixed shaft portion. The terminals of the stationary field coil (7) are routed through a groove in the fixed shaft and directly electrically connected to a stationary voltage regulator (13). The claw poles (2), formed from cold-rolled steel via blanking and forming, are positioned on either side of and encapsulating the field coil with minimal air gaps, mounted on bearings in pole housings, and rotated via a coupler from the drive shaft portion without physical contact with the field coil."
