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.

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.
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.
Getting the balance right with mechatronic systems involves the focus on a whole system and using modular motor system components for successful integration.
The new educational website by maxon motor drive.tech showcases the latest technologies and applications in the advanced motion control world. Dr Urs Kafader’s new article explains the process of getting the balance right in the critical motion control application of modern prosthetics.
Artificial limbs have rapidly moved into the world of advanced mechatronics. The synchronisation of multiple DC motors, sensors, transmissions and processors has become decentralised. The DC motors in these systems are required to fulfil an increasing number of functions that could soon encompass every human (or animal) movement. As such a huge variety of dynamics within the DC motor are required and modularity of components becomes a powerful ally. Each motor in these dynamic multi axis coordinated systems can now be locally controlled with real time field buss communication with full interpolation.

When you only have 0.2seconds to move your load maxon motors and gearheads are required.
In 2016 the Academic Motor Sports Club Zurich set a world record for electrically powered vehicles by accelerating to 100km/h in 1.513s. Maxon motors are used in the vital race car Drag Reduction System (DRS). The maxon 22mm Brushless DC motor and high powered 22mm planetary gearhead drive rear airfoil. Rotating 165˚ in 0.2 seconds means the gearhead had to withstand very high forces.

Pictured left maxon EC22 – The EC motors have excellent torque characteristics, high power, and a wide speed range of up to 100,000 rpm.
Pictured right maxon GP22 HP – Planetary gearheads are suitable for transmitting high torques of up to 120 Nm.
maxon motor planetary gearheads fitted with rubber sealed bearings when an IP rated motor or motor and encoder combination is selected.
maxon standard brushed motors of 50mm 200W and 65mm 250W sizes in 12V, 24V and 48V have the option of either an industrial housing to seal the unit in harsh environments or a 500 and 1000cpt 3 channel digital encoder in a sealed industrial housing. This standard option is also available on 45mm 250W brushless motors and 60mm 400W brushless DC motors. All motors have an extended range of planetary gearhead options which when ordered in conjunction with a sealed motor are automatically upgraded and supplied with sealed bearing assemblies. The motors do not require airflow and as such also have been supplied with custom coatings to suit specific environmental conditions. Sealed motor housings are available with axial or radial cable exits and custom uniform diameter designs.

New motors and configuration features available at the touch of a button.
Maxon have added more options to the configuration tool allowing for greater flexibility of DC motor combinations – choose from different motors, add encoders or change gearhead types and reduction.
A new “change” mode has been added that allows replacement in a configuration, for example a brushed DC motor (DCX) can be swapped to a brushless DC motor (ECX). Change the motor windings, bearings and commutation on an existing part number, as well, change the type and reduction in a gearhead. Once your configuration is complete you can buy, add to your wish list, download the specification or create the CAD data.
The guaranteed 11 day turnaround from configuration to manufacture still stands. Visit www.maxonmotor.com.au to take a look at the updates. For application assistance contact maxon motor Australia on +61 2 9457 7477.
