About The Course:

Centre for Outreach and Digital Education (CODE), IIT Madras, offers a short-term executive certificate programme on Motors and Controllers. The performance of an electric vehicle is primarily defined by its
“engine” – the motor. Although motors have been known for over a century, EVs make far more exacting demands that have brought motors to the centre-stage of technology and set new benchmarks. All
of these advances are driven by developments in power electronics and embedded firmware.
Most students and professional engineers in the automotive industry are bewildered by these rapid advances and unable to make informed decisions on the kind of motor that would be appropriate for
a vehicle. This course seeks to demystify the “Multi-physics” of the motor and make the underlying ideas accessible. Spanning electromagnetic, thermal, hardware design and control algorithms, this course bridges the gap between academic theory and industry practice. The learners will be empowered to develop motors for vehicles of their choice through a specially curated software tool for design and simulation.
