The permanent magnet motor range extends the effective nominal speed range of the rugged industry workhorses down to 100 – 850 r/min. The motors can simplify drive systems by effectively eliminating the need of speed reduction devices. They are designed exclusively for frequency converter supply, where they provide high speed accuracy even without speed sensors because they are synchronous motors without rotor slip.
The most common present drive systems, which permanent magnet motor solution could replace: Traditional AC motor, frequency converter and gear box combination, Traditional slow speed AC motor, typically 10-16-pole or slower with frequency converter, Variable speed DC
ABB-designed system that uses an underwater cable to connect a pump motor on the floor of the North Sea to a frequency converter on an oil platform 31 kilometers away has passed a string test for the Tyrihans oil field, off the coast of Norway. A general practice of the oil and gas industry is to verify the operation of equipment and systems before installation by conducting a ‘string test demonstration’ at the factory that simulates site conditions. ABB in Bergen collaborated closely with colleagues in Turgi, Switzerland (for the frequency converter), and ABB in Vaasa, Finland (for the topside
Cool atmosphere and remarkable energy savings in modern ice sports and event hall with an ABB AC Drive. A refrigerating compressor is the heart of a cooling system. In this application there are two screw compressors with 250 kW cooling capacity each. The frequency converter driven compressor runs continuously. In case high volume of cooling is required the other compressor is turned on and the output is adjusted with the frequency converter driven compressor.
The cooling system includes a coolant pumping system, a heat recovery system and a heat exchanger cooling system, all adjusted with frequency converters. The pumping system circulates
The SPAF frequency relays are intended for protection against frequncy abnormalities in generators, motors and network. The frequency relay SPAF 340 C is used for load shedding in situations where power consumption exceeds the available power of the network. In such a situation of unbalance, the network frequency tends to fall. The frequency relay can control four circuit breakers, allowing four feeders to be disconnected from the network, one by one.
Should the power deficiency still persist, the relay disconnects the plant for island operation. The operation of the relay can be based on set frequency values (f

When ABB was awarded the contract for the Québec- New England Phase II HVDC project in 1986 by Hydro Québec and National Grid USA (formerly New England Electric Systems), it was the first large multi-terminal HVDC system ever contracted. The power is generated at the La Grande II hydro power station in the James Bay area, converted into DC at the Radisson Converter Station, and transmitted over the multi-terminal system to load centers in Montreal and Boston.
Phase I of the bipolar HVDC transmission consisted of two converter stations, each rated 690 MW. One terminal, Des Cantons, is located near
The CC-E/STD is an universal standard analog signal converter from the CC-E range. This converter, with 3-way electrical isolation, operates with a rated control supply voltage of 110-240 V AC. The 4 input signal ranges (0-5 V, 0-10 V, 0-20 mA, 4-0 mA) and the 4 output signal ranges (0-5 V, 0-0 V, 0-20 mA, 4-20 mA) can be configured by means of directly accessible lateral DIP switches. The adjustment of the gain and the offset is made via potentiometers on the front of the unit. Applied supply voltage is displayed by a green LED.
