SPS IPC Drives 2013 exclusive show report

06 January, 2014

Bonfiglioli has also added six new sizes to its BMD range of synchronous motors, which now cover the torque range 1.7–50Nm, and speeds from 1,500–6,000 rpm. The motors can be used with the company’s AgiLe inverters for open-loop speed control, or with its Active Cube inverters for positioning applications. They can be equipped with EnDat or Hiperface absolute encoders for high-end positioning applications.

Control Techniques was highlighting the scalability and performance of its recently launched Unidrive M machine automation drives, using the Codesys programming environment which is provided onboard the M400 to M810 models. The M400 to M600 versions have Codesys-based PLCs while the M700 adds a real-time capability for interfacing with a 1.5-axis controller with a 250µs cycle time. The M800 model adds Ethernet communications.

Danfoss is offering 690V drives from 11–30kW in IP20 enclosures which, it claims, are the smallest on the market (520 x 230 x 242mm). The company’s 690V drives are now available in ratings up to 1.2MW.

Delta Line has a new range of three-phase stepper motors in 42, 57 and 86mm versions, covering the torque range 80mNm–6Nm. The company is also offering a series of ultraflat (9.4mm high) stepper motors from Fulling, with a step angle of 1.8 degrees, and a holding torque of 0.98Ncm.

Elmo launched a new generation of rugged integrated drives and motors that combine high-performance servomotors with its Gold servodrives. The EtherCat-based Gold Duet motor-drives cover ratings from 30W–5kW and flange sizes from 40–130, and are said to save space and wiring, and to reduce EMI, as well as cutting labour and maintenance costs.

Elmo was also showing a range of compact, high-power-density AC bus servodrives, that deliver up to 25kW of continuous power from a rectified AC input of up to 3 x 528V, with 40A continuous currents. The servodrives incorporate Elo’s Gold Line servo core designed to optimise any mechanical load, even in demanding non-linear, high-resolution applications.

Lenze was demonstrating its Smart Motor technology, first seen at the Hannover Fair, which combines AC motors with onboard controls that can deliver speeds from 500–2,600 rpm, while maintaining constant torque. Lenze says that this capability can reduce the number of different motors that users need to stock by up to 70%. The Smart Motors (above) can be operated remotely from a smartphone using the contactless NFC (near-field communication) technology.

LinMot was previewing a new generation of servodrives that includes the C1100 series for simple applications, such as replacing pneumatics, and the C1200 for more complex tasks such as synchronising axes and numerical control. Both series support Profinet and EtherCat, with the C1200 adding a modular bus that can be used with Sercos III, Ethernet IP and Powerlink. There are up to 99 programmable motion profiles and 255 storable commands. Safe Torque Off is an option.

The Italian manufacturer Lovato has a new range of drives for use on 200–240V single-phase supplies, and capable of controlling three-phase AC motors from 0.2–2.2kW. The VE1 drives offer eight preset speed curves with independent acceleration and deceleration times. They cover output frequencies from 0–650Hz and can handle 150% overloads for 60 seconds. PID functions are built in, along with analogue inputs and outputs and an RS-485 communications port.
