MAG-G (split pulse wheel)

Magnetic incremental encoder Type MAG-G 160 ... 1200 with split pulse wheel – ideal for retrofitting/upgrades

Application/installation options: 

Rotating (drive) shafts with ø from 40 mm, e.g.

  • Ship drives
  • Gas and water turbines
  • Pumped storage power plant
  • (Tandem) test stand engines
  • Large excavators in open cast mining
  • Conveyors
  • Drilling towers

Advantages

Split pulse wheel:

  • Particularly suitable for retrofitting/upgrades
  • Saves disassembly/installation costs
  • Also suitable for high speeds thanks to patented positive fit design
  • Tolerance rings ensure suitability with a wide variety of shaft qualities
  • Individual adaptation to customer shaft possible

Magnetic scanning principle:

  • Impervious to dirt and soiling
  • Large air gap and axial offset possible, (for example necessary for aligning bearing side of motor)

No integrated bearings:

  • Suitable for large hollow shaft diameters
  • Wear-free
  • No heating
  • Low noise
  • More economic than hollow-shaft encoders with bearings

IDEAS AND SOLUTIONS

INDUSTRY: Steel and rolling mills

FIELD: Hot and cold rolling mills

APPLICATION: Tandem motors

Uninterrupted processes and the quality of the rolled steel are of huge significance in rolling mills. A crucial factor is the drive technology, with a variety of drive concepts in use across the industry. Motors are also used in tandem for coilers as well as reversing mills to be able to operate with lower or higher drive power according to the material to be rolled. more
