ABOUT

Agnikul Cosmos is a company incubated at IIT Madras and we build rockets that can take satellites up to 500 kg to Lower Earth Orbit (LEO). In May 2024, we successfully completed our maiden launch from our own launchpad (India's first private launchpad). The launch has proven all the new technologies developed by Agnikul and also earned recognition from Honourable Prime Minister of India.

RESPONSIBILITIES

​

• Motor Design & Architecture – Design and develop high-power, high-voltage BLDC/PMSM motors for propulsion and actuation applications, defining architecture based on voltage, power, torque, speed, efficiency, duty cycle, mass, cooling and environmental requirements.

• Motor Sizing & Trade-offs – Perform motor sizing and design trade-offs for torque density, power density, efficiency, thermal performance, mechanical integrity and operating-speed requirements.

• Electromagnetic Design – Perform electromagnetic design and analysis covering back EMF, torque, torque ripple, cogging torque, losses, efficiency, flux density,



demagnetization margin and short-circuit behaviour using ANSYS Maxwell, Motor-CAD, JMAG, Flux or equivalent.

• Motor Mechanical Design – Design rotor, shaft, stator housing, end shields, bearings, retaining systems, cooling jackets and mounting components, considering structural integrity, manufacturability, assembly and inspection requirements.

• Rotor Dynamics & High-Speed Design – Perform rotor agile analysis including critical speeds, shaft deflection, bearing loads, balancing, stability, rotor integrity, overspeed margins and magnet retention for high-speed operation.

• Materials & Manufacturing – Select and evaluate electrical steels, permanent magnets, copper conductors, structural materials, insulation, adhesives and retaining materials based on strength, temperature, magnetic properties, density and environmental requirements; support suppliers and manufacturing teams.

• Thermal Design – Analyse copper, iron, magnet and me
