Motor design involves the process of creating electric motors that efficiently convert electrical energy into mechanical energy, tailored for specific applications and performance criteria. It requires a multidisciplinary approach, combining principles of electromagnetism, materials science, and mechanical engineering to optimize factors such as efficiency, torque, speed, and thermal management.
Cogging torque is an undesirable torque ripple in permanent magnet motors caused by the interaction between the magnetic fields of the rotor magnets and the stator slots. It leads to vibration and noise, affecting the motor's performance, especially at low speeds, and is typically minimized through design optimizations like skewing rotor magnets or stator slots.
