Process roller conveyors in reversing
rolling mills are almost exclusively
equipped with directly driven rollers today.
This places high demands on the mechanical
design of the drive. Our three-phase roller
conveyor motors for inverter-fed operation
were designed to satisfy these requirements.
They are designed as totally enclosed
asynchronous three-phase motors with a
housing of spheroid graphite iron,
ring ribs and strengthened bearing brackets.
