MOTION CONTROL: maxon’s RE 50’s “heart” is, as with all mechanically commutated maxon motor drives, the ironless rotor, which results in detent-free running and minimized mass inertia. The combination of a two-pole Neodymium permanent magnet with the patented maxon winding technology results in high torque and remarkable acceleration.
The drive measures Ø50 x 108 mm and is available with four different windings. It reaches a nominal torque of up to 0.38 Nm, a nominal speed of 2800 to 5700 rpm and an efficiency of more than 90 percent. Low nominal voltage (24.70V dc) and high power density make the RE 50 an excellent choice for the use in battery-powered applications, such as electric vehicles, transport and logistics equipment, mobile systems, robots, etc.
Pre-loaded bearings contribute to low-vibration and quieter running and an extensive life span. The well proven maxon modular system offers matching planetary gearheads, encoders and control systems. Look for more information soon on a dust and splash water protected RE 50 version, which will be available with an optional brake.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
