Rare-Earth-Free Brushless Roof Motor


Following our rare-earth-free brushless wiper motors, we are expanding our lineup of rare-earth-free motors, and this brushless roof motor marks the second addition to that lineup. Furthermore, while rare-earth-free motors generally tend to be larger, this product achieves a more compact and lightweight design compared to conventional models.


This motor is a brushless motor for opening and closing automotive roofs and sunshades, developed jointly with Webasto Roof &Components (Headquarters: Stockdorf, Bavaria, Germany; hereinafter “Webasto”), a leading provider of automotive roof systems, and we have begun supplying it to German luxury automakers through Webasto.


In the roof motor market, our sales volume for fiscal year 2025 is approximately 14 million units, representing a 36% market share; according to our research, this represents the top global market share. Leveraging this strong market position, we aim to expand the range of vehicle models equipped with these motors in collaboration with Webasto, with a target of 2 million units sold annually.

We will continue to develop rare-earth-free motors, contributing to the electrification of automobiles, improved comfort, and reduced environmental impact, with the aim of sustainably enhancing corporate value.
