DC motors steering the rear wheels of race cars.
Maxon actuators, DC motors, gearheads and encoders help to improve the handling and overall driving stability of a race car through rear wheel steering, with up to 3 degrees transfer per side.
A maxon supported Young Engineers Student project is developing mechatronics for steering the rear wheels of a race car. At the heart is a maxon spindle drive (linear actuator) that converts rotational movement into linear movement. Fitted with an EC-4 pole brushless DC motor to provide up to 200W of power, GP32 planetary gearhead for torque and two maxon EPOS2 position controllers with HEDL encoders to set the steer angle of the wheels. The maxon drive system is connected to the cars internal controls to calculate the desired steer angle.
The main issues for the engineers were lightweight, small components, with enough force to set the required steer angle and trustworthiness of the components to work reliably without fail.

|Linear Actuator||EC-4 pole DC motor||GP32 Planetary gearhead|
|maxon’s linear actuator (spindle drive) convert the power generated by the motor into feed velocity and feed force.||The EC-4 pole DC motors have no cogging torque, high efficiency, and excellent control dynamics.||Planetary gearheads are suitable for transferring high torque up to 180 Nm.|
|EPOS2 encoder||HEDL sensor|
|EPOS is a modular, digital positioning controller by maxon motor. It is suitable for permanent magnet-activated motors plus encoders with a range up to 750 W continuous output power.||maxon encoders allow accurate evaluation of the speed & angle position and form the framework for high-precision control loops.|
