-> maxon DC motor: Nothing else comes as close to 100%. DC motors with moving coil rotor and high
performance permanent magnets
maxon DC motor programs may be distinguished as follows:
RE-Program

• D 6 - 75 mm
• 0.3 - 250 watts
• Highest performance by using Neodymium- (NdFeB) magnets

S-Program

• D 22 - 32 mm
• 6 - 15 wattsAlNiCo magnets
• Flexible program with many versions

A-Program

• D 15 and 20 mm
• 0.8 and 1.2 watts
• AlNiCo magnets
• Designed for optimum manufacturing efficiency the A-Program offers many of the advantages of the S-Program at lower cost.

F-Program

• D 30 - 60 mm
• 2.5 - 80 watts
• Ferrite magnets
• Often a very interesting price/performance ratio, in spite of the higher volume-to-power relationship.

Characteristics

• Mechanical commutation (graphite or precious metal brushes)
• Excellent volume/performance ratio
• Highest efficiency
• Low inductance
• No magnetic cogging
• High acceleration thanks to a low mass inertia
• Low electromagnetic interference
• Linear characteristics
• High reliability
• Multiple combination possibilities with gears, feedback devices and control electronics

Some applications
space robots, aircraft seats, packaging systems, conveyors, chip mounting systems etc.
