DC electric motor with ironless rotor
0.3 - 250 W
maxon motor
DC motors with moving coil rotor and high performance permanent magnets
maxon DC motor programs may be distinguished as follows:
RE-Program
- Æ 6 - 75 mm
- 0.3 - 250 watts
- Highest performance by using Neodymium- (NdFeB) magnets
S-Program
- Æ 22 - 32 mm
- 6 - 15 wattsAlNiCo magnets
- Flexible program with many versions
A-Program
- Æ 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
- Æ 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.
