High performance motor control
Published: 08 May, 2019
ABB has announced it has expanded its all-compatible drives offering to include the ACS6080 medium voltage (MV) drive for critical applications. ABB says the new drive introduces a breakthrough control technology, it has developed, that brings high performance motor control to demanding processes used in industries such as mining, metals and marine and the drive also enables plants to operate more efficiently and produce higher quality output.
Traditionally, achieving high dynamic performance and excellent power quality required hardware with multiple devic-es. However, this increase in components could decrease reliability of the operation. The ACS6080 drive maintains the same highly reliable hardware as its predecessor, the ACS6000, and includes the new advanced control capability, known as Model Predictive Pulse Pattern Control (MP3C).
ABB says its MP3C technology combines model predictive control with optimised pulse pattern to modulate the semi-conductors. This means that at every point in time this control can anticipate the best motor operation point by finding the perfect compromise between dynamics, efficiency and harmonic distortion.
The new control enables system integrators and plant operators to maintain stability, while reducing investment and operational costs by using a smaller drive or a smaller motor. The increased power capability of the ACS6080’s single power module reduces the footprint of the drive by up to 20%. The new control helps to reduce operational cost in two ways: it is more energy efficient than other control solutions, and maintenance costs are reduced as there is less mechanical and thermal stress on the equipment leading to longer lifetime of the components.

RITTAL says its RiLine60, a fully shielded flexible busbar system with a wide range of busbar adaptors, has been extended to include a new OM adaptor ideally suited for the control panel manufacturer. Rittal says by combining contemporary design and outstanding safety technology, with easy design and speedy installation, the RiLine60 offers a safe method of distributing power within cabinets.
Compressed air specialist BOGE has launched the BOGE airstatus, a new remote diagnostic tool designed to deliver maximum control and reliability. Boge says in the age of the computerisation of manufacturing, its pioneering technology redefines and enhances the communications between man and machine and supports users to optimise compressed air performance.
