Single-cable distributed servodrives ‘can save 80%’

Kollomorgen claims that a new distributed servodrive technology, which uses a single hybrid cable to link IP67-protected servo controllers near a motor to central power modules located in switchgear cabinets, can cut costs by more than 80% by saving cabinet space and simplifying the cabling.

Integrated PM motors deliver high power densities

The German manufacturer Baumüller has integrated a range of permanent magnet synchronous motors, previously used as part of its powerMela system for mobile drives, with its b maXX 5000 controllers to produce efficient 80kW and 140kW drives with high power densities, suitable for use in restricted spaces.

Servodrives are '25% cheaper than rivals'

A new range of servodrives from the German manufacturer Metronix has been designed to be about 25% cheaper than comparable European drives. The company has achieved this using various techniques, including embedding features that would usually be provided using expansion slots. It has also split the electronics across two PCBs, thus reducing the number of layers needed and allowing single-sided component mounting.

IE4 PM motor package will pay for itself in two years

At the recent SPS IPC Drives show in Germany, Yaskawa was demonstrating a package of a permanent magnet (PM) motor and a matching inverter which, it says, operates with a higher efficiency than the proposed IE4 level and will pay for itself in about two years through increased energy savings compared to an IE2 motor-and-inverter combination.

Next-generation drives offer 3ms scan times

Mitsubishi Electric has previewed its next generation of general-purpose VSDs (variable speed drives) at the SPS IPC Drives show in Germany. The company also showed a new 690V addition to its earlier FR-A700 series.

‘Revolutionary’ encoder adapts to any shaft size

The German sensor manufacturer Baumer has developed a “revolutionary” magnetic encoder technology that provides precise angular and speed measurements from large shafts of almost any diameter.

Microdrive is ‘the smallest with a built-in HMI’

The Brazilian drive technology and motor manufacturer WEG has launched a mini frequency inverter which, it claims, is the smallest to incorporate an LCD HMI. The CFW100 inverter, which made its debut at the recent SPS IPC Drives show in Germany, has a built-in micro-PLC that supports IEC 61131-3 programming, making the drive suitable for simple applications such as swimming pool pumps, small fans and special-purpose machines

Passive harmonic filter ‘exceeds active filter efficiencies’

The Canadian power quality specialist Mirus International has announced a high-performance harmonic filter that, it claims, matches the performance of active front-ends (AFEs) and is at least 2% more efficient than active harmonic filters (AHFs). It adds that the Lineator HP (high performance) filter is also free from the high-frequency harmonics and noise issues associated with inverters used in active systems.

Microdrives include autotuning sensorless vector mode

At the recent SPS IPC Drives show in Germany, Parker Hannifin unveiled a new family of microdrives aimed at speed or torque control applications in the power range 0.2–15kW. It claims that the AC10 drives, which come in five frame sizes, are among the smallest of their type, and offer functions normally associated with higher-specification drives.

‘World’s most popular PLC’ enters a new generation

Mitsubishi Electric has unveiled a new generation of its FX compact PLC, with the claims that it is three times faster, and will cut running costs and energy consumption. At the recent SPS IPC Drives show in Germany, the company also launched a new version of its high-end iQ series modular PAC (programmable automation controller), which can control up to 192 axes and is said to cut development, maintenance and operating costs.

3G gateway simplifies remote management of equipment

The Swedish industrial communications specialist HMS Industrial Networks has launched a communication gateway that, it claims, will make it easier to configure, monitor and control industrial equipment remotely.

Submersible PM motor can boost outputs by 50%

The US-based flow control specialist Flowserve has announced a submersible electric motor that uses permanent magnet technology. It claims that the pump motor is up to 10% more efficient than asynchronous motors, has a longer operating life, and can boost power outputs by nearly 50%.

Explosion-proof motors add a cast-iron option

Siemens Drive Technologies division has announced a range of explosion-proof motors with cast-iron housings aimed at challenging hazardous and corrosive environments such as those found in the chemical, pharmaceutical, oil and gas sectors. The motors expand Siemens’ Simotics XP 1MB1 portfolio which, until now, has been available only with aluminium housings.

Instruments can perform real-time power analyses

Yokogawa has launched a pair of portable instruments that can perform real-time measurement and analysis of electrical power variables. The ScopeCorder DL850E and the DL850EV (dedicated to vehicle applications) instruments combine the functions of a high-performance digital oscilloscope with those of a multi-channel data-acquisition recorder that can capture and analyse transient events and trends for periods of up to 200 days.

'Premium micro-PLC' outperforms similarly priced logic blocks

Mitsubishi Electric has announced a new micro-PLC which, it claims, creates a new class of device – which it calls a “premium micro-PLC” – offering many of the functions of compact PLCs, but at similar price to a logic block.
