Compact Rapid Attack Weapon 

This project is dedicated to the development of a 100 hp powerplant tailored for a Compact Rapid Attack Weapon (CRAW) propulsion system. It introduces an innovative Gapless Rolling (GR) electric motor, wherein magnetic rollers replace the conventional airgap. This pioneering motor design represents a transformative exploration of gapless rolling machines in electric propulsion. The key attributes of high power density (kW/kg), compact size, and reduced maintenance align seamlessly with the specified requirements for the power plant embedded in the CRAW.

In addition to the motor, the project places equal emphasis on the development of an efficient battery pack and a sophisticated bipolar motor drive. These components are integral to the overall performance of the powerplant. The battery pack is designed to meet the high current requirements and spatial constraints of the CRAW, while the bipolar motor drive, interfaced with the battery pack, is tailored to optimize the power output of the GR motor. A dedicated control strategy ensures the motor maintains a steady speed, crucial for the CRAW's operational efficacy.
