Gurgaon-headquartered Sona Comstar, a leading supplier of differential bevel gears and assemblies to passenger and commercial vehicle OEMs in India and overseas, which has diversified into e-axles and e-motors for electric two- and three-wheeler OEMs in the domestic market, has lined up a comprehensive display of futuristic technologies at its stall at Auto Expo 2023, in New Delhi’s Pragati Maidan.

The company will showcase a range of advanced driver assistance systems (ADAS) sensors developed by Serbia-based Novelic in which it recently announced plans to acquire a 54% stake at Rs 356 crore by end-Q4 FY2023.­­­

Novelic has developed an in-cabin radar-sensing technology to monitor vehicle occupants using millimetre or mmWave technology which offers a wireless solution to ascertain presence of passengers inside a vehicle to offer functionalities such as triggering seatbelt alarm and airbag system activation.

The technology company also offers perception solutions and full-stack embedded systems and is vertically integrated across the value chain from machine learning and perception software to hardware and chip design. Novelic’s partners include global automotive OEMs, autonomous vehicle makers, Tier-1 suppliers and chip manufacturers like Infineon and Texas Instruments. 

SRMs for two-, three- and four-wheeled EVs

Sona Comstar will also showcase its range of switched reluctance motors (SRM) for two- and three-wheeler high-performance motorcycles and four-wheeler cargo-delivery EVs. The compact, lightweight magnet-less motors arise out of the company’s strategic partnership with Canada’s Enedym which is a leading supplier of electric propulsion and electrified powertrain solutions.

While the two-wheeler SRMs will be targeted at vehicles having 10kW or greater nominal power delivery requirements, for four-wheeler cargo delivery electric vehicles, these will be suitable for vehicles having 20kW or greater nominal power. Sona Comstar is likely to commence series production of these motors in India later this year.

Finally, the Tier-1 major will also showcase its electronic differential lock for SUVs and range of high-voltage (300V) electric motors for commercial vehicle electric bus applications. The company also intends to foray into the area of high-voltage electric motors for electric passenger vehicles in the coming years. "We will venture into the space at the right time and in a step-by-step manner. We have gradually moved up from 24V to 48V and now 96V in the e-motor space and will certainly offer reliable and high-quality products EV drivetrain components for passenger vehicles with the right and mature technology,” said Vivek Vikram Singh, MD and Group CEO, Sona Comstar.
