Less is More: Reduced Number of Variants, Smaller Size.

Lenze has developed a decentralised drive solution that is specially tailored to the requirements of horizontal materials handling systems. Coming from Lenze as a specialist in Motion Centric Automation, this mechatronic solution combines the well-known Lenze Smart Motor with the g500 gearbox series. The efficiency of the Lenze Smart Motor plus gearbox is more than 94 per cent over the entire ratio range. This enhances the energy efficiency of the machine in question as a whole. With a single version of this motor-gearbox combination, variable motor speeds with a constant torque are possible. This renders superfluous many of the different variants of such combinations that are normally needed today. What's more, the motor's speed of rotation can be adjusted with the help of a smartphone and NFC technology.

In the area of horizontal materials handling, many drive concepts now in use rely on complex frequency inverters in order to achieve a high starting torque. In contrast, the continuous torque is usually relatively low. As a result, the drives are over-dimensioned and consume far too much energy. Lenze has taken a very close look at such applications and questioned the conventional solutions usually applied in these cases. The result of this approach, which is aimed at improving the concrete application, is a smart drive package that performs its respective materials-handling tasks very precisely and effectively. This is made possible by the intelligent interaction of the components.

The Lenze Smart Motor combines the simplicity of a mains-operated motor with the advantages of an electronic drive control unit, whereby the electronics and the software are integrated in the drive and, together with the mechanics, form a single aggregate unit. Due to the freely adjustable speed, the variety of different drives in use can be reduced by up to 70 per cent as only one geared-motor version is sufficient for all tasks. Time-consuming and costly version management is thus no longer necessary, as a result of which the number of drives that the mechanical engineering company has to keep in stock can be reduced and costs can be lowered sustainably. Moreover, the operator can control the equipment with a smartphone and the use of "near field communication". The advantage of all this is that the motor's speed can be converted into torque intelligently and precisely. Due to intelligence in the terminal box, the Lenze Smart Motor can flexibly cover speeds of between 500 to 2600 revolutions per minute at constant torque. Mechanical engineering companies and plant operators can therefore profit from this carefully designed drive package in several different ways: a highly modern operator control concept, low energy consumption and thus reduced operating costs and fewer different drives with different ratings.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as ...

EGCS-D0 Accelerometer Now Available in 10,000g Range

Measurement Specialties, Inc. (NASDAQ: MEAS) has recently redesigned the EGCS-D0 accelerometer to enable it to accurately and reliably measure up to ±10,000g. This rugged device is critically damped, which is the ideal mechanism to protect the accelerometer against ±20,000g impacts and prevent sensor ringing. The EGCS-D0 accelerometer is now available in ranges from ±5g to ±10,000g which makes it ideal for both critical low-g measurements and high-g impacts. These units feature a Wheatstone Bridge mV output with a standard compensated temperature range of 20ºC to 80ºC (other options available). The EGCS-D0 was specifically designed for impact and shock testing in auto safety, aerospace, military and civil engineering applications. Designed to be bolt-mounted, this device operates from 2-15Vdc excitation with electrical output ratiometric to voltage input. Optional triaxial mounting blocks (MTG-F4), signal conditioners (Model 101) and auto-zero inline amplifiers (Model 140) are avai...

Ilix Cermet Reamers Are Ideal For Dry Machining Engineers Cutting Tools, the UK agent for Ilix, has introduced Ilix solid-carbide and cermet reamers for the machining of hard metals. The machine reamers 6372C and 6323 allow the production of high-precision holes with good surface finish. Compared with HSS, the solid-carbide qualities enable the increase of cutting parameters and tool life. The quality of the reamers is said to guarantee high performance, even for hard metals with a resistance more than 1200N/mm2. The Ilix carbide 6372C range of hundredth reamers is from 0.98mm through to 12.05mm in increments of 0.01mm. The reamers are manufactured to a tolerance of +0.000 - +0.004mm. The cermet reamers 6323 have new cutting geometry developed by Ilix. These reamers are said to be ideal for steel machining, having high chemical stability during the cutting process. They offer good wear resistance due to the high hardness and have low material adhesion. The Ilix cermet reamer is said to...
