WO/2025/188315

Problem Solved

Traditional electric motors often have slots in their stator design, which can lead to inefficiencies such as increased energy loss, noise, and vibration. These challenges limit the performance and longevity of electric motors, making them less efficient and more costly to maintain.

Core Features

This invention introduces a slotless electric motor design. It comprises two cylindrical layers, with the inner layer made from non-conductive, non-ferrous materials and the outer layer from ferrous materials. The motor features orthocyclic windings placed in an air gap between these layers, secured with a dielectric potting compound. A unique mounting system with raised ridges and slots facilitates easy connection of wire connectors.

Inventive Step

The novelty lies in the slotless design and the use of orthocyclic windings, which are more efficient and reduce energy loss. The innovative mounting system and the use of a dielectric potting compound further enhance the motor's performance by reducing noise and vibration. This design offers a more efficient and durable alternative to traditional motors.

Benefits

The slotless electric motor is quieter, more efficient, and has a longer lifespan than traditional motors. It reduces energy consumption, leading to cost savings and a smaller carbon footprint. The design also simplifies manufacturing and maintenance processes.

Broader Impact

This invention could significantly improve the efficiency of various industries relying on electric motors, such as automotive and manufacturing. By reducing energy consumption and noise pollution, it contributes to sustainability efforts and enhances the quality of life.
