Constant 200 W from 40 mm motor
Second Quarter 2005
Electrical switching & drive systems & components
maxon set its sights high when developing the new 30 mm diameter power motor, focusing clearly on customer orientation. At 200 W output power, the EC-powermax is one of the best drives available today in the international drive sector. The new optimised maxon winding technology gives it significant performance benefits. The stator is grooveless which means there is no detent, providing excellent control characteristics, particularly for positioning operations. It is also much quieter in the upper speed range, as there is less mechanical vibration.
The 4-pole rotor is fitted with the best available magnetic material, with the magnetic field scanned for electronic commutation. The motor design has been kept deliberately robust and promises to be highly reliable, even for the expected high currents. The increase in the motor's characteristics which define a motor's output capacity is 5,7 min-1mNm-1, ie, four times better than the comparable 2-pole version.
The motor can be combined in the modular system with 42 mm planetary gearheads, digital encoders up to 100 pulse and brakes. The drives form a high-powered drive system in combination with electronic maxon controls Type DES or a modern positioning system.

Energy management system for electrohydrostatic actuation systems
Electrical switching & drive systems & components
In the machine manufacturing industry, more drive systems are being converted from servo-hydraulic throttle to electrohydrostatic actuation systems. The four-quadrant capability of the electrohydrostatic pump unit and servo drive used in this technology, in combination with the new Moog energy management system, allows regenerative power flows generated during braking or pressure relief to be stored and reused.
