India’s electric vehicle market is growing fast enough that the engineering teams behind it are under continuous pressure to deliver better products on shorter timelines with smaller budgets than the established global players they are effectively competing with. In the electric motor and drivetrain space specifically, this pressure is acute.
An electric motor for a vehicle application is a multi-physics design problem. Electromagnetic performance determines efficiency and torque output. Thermal management determines continuous power rating and operational reliability. Structural integrity of the rotor determines the maximum speed the motor can sustain. NVH behavior of the motor determines how much noise and vibration it contributes to the vehicle. These physics domains interact with each other. A rotor design change that improves electromagnetic performance may worsen the thermal behavior or the NVH characteristics.
Designing this system by building physical prototypes of each iteration and testing them through the performance envelope is technically possible but commercially unviable for the pace that India’s EV market demands. A single motor prototype and full test program can cost 30 to 60 lakhs and take three to four months. Running five or six iterations to optimize the design that way is neither affordable nor fast enough for most Indian EV programs.
Simulation-first means that the primary engineering decisions about motor topology, winding configuration, rotor geometry, and cooling architecture are made based on simulation results before a physical prototype is built. The simulation program runs thousands of virtual design iterations to find the configuration that best meets the performance requirements. The first physical prototype is built from a design that has already been optimized in the virtual environment, not from a first-cut guess that needs to be refined through physical testing.
For electric motor design specifically, this involves electromagnetic FEA to model the flux distribution and torque ripple, thermal simulation to model heat generation and cooling performance under drive cycle conditions, and structural analysis to validate rotor integrity at maximum speed. In an integrated simulation environment like Simcenter, these analyses can exchange data with each other so that the coupled effects between domains are captured.
The honest picture is mixed. Some of the better-capitalized Indian EV startups and the OEMs with established engineering capabilities have built simulation teams and use multi-physics simulation as a core design tool. Ola Electric, Ather Energy, and the major two and three-wheeler OEMs that have moved into EVs are examples where engineering investment levels are sufficient to support this kind of capability.
A larger number of smaller EV companies and motor suppliers, particularly those that entered the market quickly to take advantage of the FAME scheme and PLI incentives, are still doing most of their motor development through physical prototyping and test. This is not because they do not understand the value of simulation. It is a combination of the cost of the software, the shortage of engineers in India who can run electromagnetic and thermal co-simulation effectively, and the pressure to ship product that makes investing time in building the simulation capability feel like a luxury.
The competitive pressure from Chinese EV motor suppliers, who have invested heavily in simulation-driven development and are delivering motors with very high power density and efficiency at aggressive prices, is making development cost and speed a survival issue for Indian motor companies. You cannot compete on development cost and speed with a physical-prototype-first approach against competitors who are running simulation-first development at scale.
Additionally, the export opportunity for Indian EV components to markets in Southeast Asia and Europe requires meeting international certification standards and demonstrating design process maturity that increasingly includes simulation documentation as part of the technical file. For companies with export ambitions, simulation capability is becoming part of the market access requirement rather than an optional investment.
