EXPERTISE
Experience that shortens the path to a solution New motion control approaches do not start from scratch. Proven platforms make expertise built up over many years available from the outset.

Developing a servo drive or motion controller may not seem particularly complicated at first glance. Many microcontroller manufacturers offer exten- sive software development kits (SDKs) and libraries for controlling brushed and brushless DC motors. Today, a wide range of highly integrated compo- nents is also available to handle various motor con- trol functions. A skilled engineer can use these resources to develop functional control solutions in a relatively short time, even without in-depth expertise in con- trol engineering and power electronics. This may be entirely sufficient for simple applications. As requirements become more complex, however, this approach soon reaches its limits. The demanding requirements of highly dy- namic ironless motors, uncompromising minia- turization, and stringent efficiency targets com- bined with sophisticated thermal design require specialist expertise and experience. The same ap- plies to clock synchronization across a wide range of communication interfaces and modern sensor systems. If high production volumes and availabil- ity over several decades are also required, it be- comes clear why maxon decided to develop its own electronics as well. The crucial point, however, lies elsewhere: a drive system reaches its full potential only when
