Rohm Semiconductors has introduced the brushless (BL) DC motors for the Indian market.
At a gathering in Bangalore, Rohm detailed the line-up for energy efficient ceiling fans and room AC outdoor unit fans. Designed specifically in India, for India, the use of BLDC motors can reduce power consumption of home appliances and industrial equipment by up to 50 percent.
Nakamura Daisuke, MD, Rohm Semiconductors (India), said that quality has always been the company’s top priority. Sixty percent of Rohm’s revenue come from Asia. Rohm started its India design center in 2014. The design center does 100 percent inhouse production – from IC chip design and layout to photomasking.
Britto Edward Victor, head, India Design Center, Rohm Semiconductors (India), added that India was currently the largest market for ceiling fans as well as air coolers. India has been estimated to produce 73 million ceiling fans per year by 2020. It currently produces 40 million ceiling fans at 10 percent growth year-on-year.
Using BLDC motors, instead of AC induction motors, could lead to a saving of 35W and ~50 percent in savings. Rohm has a smart integrated power module (IPM) for BLDC motors. Rohm also made the smallest package in the industry. The BLDC motors are designed for the Indian market and helps reduce the time to market.
Rohm has been providing analog, power, sensor, and mobile solutions. Rohm has been focusing on automotive, power and motor, as well as smartphones. Daisuke added that power emerged as a key area. Rohm started off with power and motors. Rohm also offers mobile solutions, called RASMID.
