Title: Mohsen Erfanfar: Innovator in Electric Motor Technology
Introduction
Mohsen Erfanfar is a notable inventor based in Carmel, IN (US). He has made significant contributions to the field of electric motor technology, holding 2 patents that showcase his innovative approach to engineering.
Latest Patents
One of his latest patents is titled "Modes of cooling hybrid electric machines." This invention presents a system and method for cooling an electric motor that includes a plurality of laminations defining a lamination stack, a coolant passage, and a motor winding. The design allows coolant to be pumped into the passage and forced along the entire length of the lamination stack, ultimately spraying the coolant on the motor winding to enhance cooling efficiency.
Another significant patent is the "Method of rotor assembly without the hub." This method provides a way to assemble a rotor without the use of a rotor steel hub. It involves forming first, second, and third lamination stacks by stacking individual rotor laminations together. The stacks are then cast to lock the laminations, resulting in a rotor assembly that reduces total cost and manufacturing cycle time while improving performance and efficiency.
