Motor Air-Core Coil - Project Details

Application

❖ Coreless Cup Motors: Featuring a coreless, hollow-cup rotor structure, these motors offer high response speeds and low inertia, making them frequently utilized in robotics and aerospace applications.

❖ Linear Motors: The primary or secondary coils can be designed with a hollow structure to minimize cogging effects and enhance motion smoothness.

❖ High-Frequency Motors: Such as certain ultrasonic motors or high-speed spindle motors, which employ hollow coils to reduce high-frequency losses.

Key Considerations for Coil Design

❖ Winding Topology: Techniques such as honeycomb or helical winding are employed to optimize space utilization.

❖ Material Selection: High-temperature enameled wire or Litz wire is selected to mitigate the high-frequency skin effect.

❖ Support Structure: Epoxy resin or composite materials are used to secure the coils, thereby ensuring mechanical integrity.
