116 E-mobility is in. Virtually every reputable car- maker is working hard to expand its portfolio of hybrid and e-vehicle products. For mecha- tronic systems suppliers like Brose, which al- ready provides around 200 million motors to the market, this presents both an opportunity and a challenge. On the one hand, the decline of the combustion engine means that belt- driven auxiliary systems must also be electri- fied. This opens up new business potential. On the other hand, OEMs are not taking a stan- dardized approach. Instead, they are deploying a broad spectrum of electrical systems – de- pending on the type of drive and the manufac- turer’s electronics philosophy – with voltages ranging from 48 to 470 to up to 810 volts. Flexible modular system Consequently, almost all of the family-owned company’s motors and drives have to work with different operational voltages so that they can also be used in hybrid or electric cars. Brose helps car manufacturers with a cost- effective solution: a cross-product modular motor and electronics system with standard- ized components covers power ranges from 250 W to 20 kW and voltages ranging from 12 to 810 V. This transfers Brose’s decades of experience and proven technologies to e-vehicles. Independent of the vehicle drive, carmakers benefit from short development times, robust products, a high level of flexibil- ity and economies of scale in global produc- tion – even in the ramp-up phase for new products. The unique feature of Brose’s modular system: the stators and rotors can be combined in any number of ways using standardized interfaces. What’s more, the motors and electronics are also uniform; the order of assembly is always the same. The automotive supplier achieves different power densities by using various types of magnets or adjusting the winding. Brose estimates that it will manufacture over ten million modular drives annually in the coming years. One for all By Willi Parsch, Vice President Development Drives, Brose Group The increasing electrification of the drive train is making conventional 12-volt electrical power systems less important as they are being replaced by a variety of architectures ranging from 48 to 810 volts. Brose is responding to these new demands with a modular motor and electronics system. The mechatronics specialist hopes to use this technology to prepare its products for flexible usage scenarios in a wide range of operational voltages.
