Description

Drive technology
All conveyor drives are equipped with HXR
type six-pole totally enclosed fan-cooled
squirrel-cage motors fed by ACS 600
frequency converters. They are low-voltage
drives for a supply voltage of 690 V, all
designed for 4-quadrant operation, i.e.
working as motors and generators. The
electrical energy generated during the
braking process is fed back into the grid
through grid inverters.
Two different concepts have been
implemented on the frequency-converter
systems, depending on the number of
motors in question:
• single drive
• multi drive
While the single drive, simply speaking, consists of one grid-side and one motor-side
inverter, the multi drive is more complicated. Here one diode rectifier and one grid
inverter each feed in parallel on one common DC busbar which, in accordance with
the drive configuration, supplies up to three inverter units.
Quality criteria
Introducing speed control for belt conveyors, the customer has defined precise
economic and technological objectives:
• power savings through a load-dependent control of the belt speed
• efficiency increase
• minimisation of system perturbations
• reduction of gear and belt wear
Demanding quality criteria have been specified as benchmarks for accomplishing
those objectives. They include in particular:
• dynamic torque characteristics at starting and stopping
• efficiency with different belt speeds and loads
• power factor (cos ϕ ≥ 0,95)
• system perturbations (THD ≤ 10%)
ABB Automation, the supplier of the electrical-engineering part of the system, could
successfully prove that all agreed criteria have been attained.
