Electric motor with improved cooling system
A recently granted patent (Publication Number: US11876419B2) discloses an innovative design for an electric motor with improved cooling capabilities. The motor comprises a rotor and a stator, with the stator featuring a yoke, teeth aligned parallel to the motor's axis of rotation, field coils wrapped around the teeth, radial baffles, and various coolant circulation paths. These paths include channels between field coils, radial baffles, and teeth, ensuring efficient cooling of the motor during operation. Additionally, the design incorporates circumferential baffles and electrical bussing to enhance the cooling process further.
Furthermore, the patent also covers a method for cooling the electric motor, involving circulating coolant through specific coolant circulation paths within the motor's structure. This method includes directing coolant through channels between field coils, radial baffles, and teeth, as well as utilizing additional coolant channels between the radial ends of adjacent teeth. By implementing this cooling method, the electric motor can maintain optimal operating temperatures, ensuring performance and longevity. Additionally, the method involves circulating coolant between bus rings in the electrical bussing system, further enhancing the overall cooling efficiency of the motor.
