Magnet-equipped motors on the starting grid

21st February 2013

As the new Formula 1 season gets under way, new rules on aerodynamics have put Maxon motors at the forefront of technology to make races more exciting.

In 2009, for the first time in over 40 years, F1 drivers will be permitted to alter the aerodynamic characteristics of the car while it’s moving, significantly boosting their chances of overtaking.

The new rule allows for a small but significant six-degree movement in adjustable flaps on the vehicle’s front wing, up to twice per lap; increasing downforce to combat the 'upwash' in a rival car’s wake, before cutting drag at the crucial moment for a sudden burst of speed.

However, teams wishing to take advantage of the change needed to source drives capable of performing the precise movements stipulated, with absolute reliability, while subject to extreme conditions the front tip of a 220mph (360 km/h) grand prix car; but also small and light enough to avoid compromising precious weight and aerodynamic calculations.

Quickly, maxon’s Neodymium magnet-equipped motors established themselves as a ready solution to this challenging new task.

Because of the world-leading NdFeB magnets, the miniature motors deliver immense low-speed torque for their weight and size, enabling teams to gain excellent results from the wing actuator using the smallest possible device.  

Indeed, even teams who have yet to adopt variable aerodynamic systems use maxon motors in fuel and oil pumps, fans, or for other critical functions.  This year, virtually every F1 car will rely upon maxon technology.
