With the spread of electric vehicles (EV) and hybrid vehicles, the need for traction motors is increasing.
A traction motor is the heart of an automobile that replaces the engine, and efforts are being made to improve its efficiency and reduce its size and weight in order to extend the torque characteristics that determine the dynamic performance of automobiles and the cruising range. In addition, the demand for quality such as quietness and high reliability is rapidly increasing in order to a comfortable car life.
The EV motor case is one of the main parts that make up the traction motor and is becoming thinner and more complicated in shape due to the need to reduce weight. Machining of such thin-walled and complicated-shaped workpieces tends to be difficult due to the reduction in rigidity of the workpieces and fixtures. Tungaloy proposes an optimal tool lineup and processing methods for motor case machining, and contributes to the problem solving and the productivity improvement.
