A NEW RANGE OF SLOTLESS MOTORS FOR HIGH SPEED APPLICATIONS
New from Nanotec is the slotless BLDC motor DS16, which is said by the company to offer an efficient solution for high-speed applications – such as drills, grinders and even tattooing instruments. The stator of the motor consists of ring-shaped plates with
New from IDEC Corporation is the FL1F SmartRelay, an upgrade to the previous FL1E model. The device can now accommodate small- to medium-sized OEM machine control and other applications, the company explains. The FL1F SmartRelay CPU module has
eight discrete inputs and four discrete outputs. In addition, there are six types of I/O expansion modules, and up to 12 I/O expansion modules can be added to the CPU, expanding the I/O capacity to 60 I/O. Maximum configurations are 24 discrete inputs, 20 discrete outputs, eight analogue inputs and eight analogue outputs. Each discrete output can switch up to 10A. These I/O points are monitored and
controlled through the use of the device’s expanded programming capacity with a maximum 400 function blocks. In addition to industry standard function blocks, five new types are supported: astronomical clock, analogue filter, maximum and minimum, average and stop watch. Additional features include an improved
LCD operator interface which can display six lines, each with up to 20 characters. Selectable white, amber or red backlighting allows operators to easily distinguish alarm and alert status at a distance, and an external Text Display Panel, which mimics the CPU display, is also available to provide an additional operator interface point. The FL1F SmartRelay’s Ethernet port can be used to connect to: a PC for programming; text display panel; other FL1F controllers; and the internet for remote monitoring.

a flat winding on the inside. Since the windings don’t have an iron core, the motor’s inductance is very low and the current rises rapidly. In addition, the amount of iron lost is greatly reduced and the motors have a high efficiency rating. During slow operation, the lack of torque ripple has a positive effect. DS16 is available in size S with a power output of 3.7W at max. 27,000 rpm; in size M with a power output of 10W at max. 30,000 rpm; and in size L with a power output of 25W at max. 29,000 rpm. The low inductance of these slotless motors, combined with the PWM frequency of the controller, can lead to high current ripple generating additional heat. Therefore, additional motor throttles need to be used between the controller and motor.

FIRE-RATED ENCLOSURES FOR DEMANDING ENVIRONMENTS
According to enclosure manufacturer CE-TEK, one of the biggest challenges is providing a suitable housing capable of maintaining electrical integrity and continuity during and after a building fire. To meet the demands, the
company offers the CEX range, which consists of over 42 size options manufactured in high grade materials including electro-polished and orbital finished 304L/316L stainless steel, and powder coated mild steel. Standard protection is to IP66 with IP67 and IP68 versions available on request. The enclosures meet all the
INDUCTIVE ANGLE ENCODERS
There are now 100 million product variants in Zettlex’s IncOder range of inductive angle encoders. The new range includes mini IncOders at 37mm diameter, midi IncOders at 58mm diameter and maxi IncOders from 75 up to 300mm diameter. In addition, a new range of mechanical formats are available, as well as options on connections and cabling. Customers can also set pules per rev for A/B pulse devices from the part number. Of additional benefit, the range has been improved, with faster update rates which are now at 10kHz for absolute digital outputs.

stringent conditions set out by British Standards: BS5839-1: 2013 Section 26.2e. This states that enclosures should be able to support cables so that circuit integrity is not reduced below that afforded by the cable when exposed to fire, whilst still maintaining PH120 classification for continuity of power supply. The British Standards test replicates a fire
scenario, rapid heat build-up (the enclosures were tested up to 970˚C) and the process of extinguishing with water, and mechanical shock associated with masonry collapse. As a result, the enclosures are designed
to ensure building fire safety in over-ground and underground rail applications, road tunnels, oil & gas installations, and other public places where electrical power supply, emergency lighting and public address systems are required to remain fully operational in the event of a fire.

www.ce-tek.co.uk NEW LUBRICATING GREASE FOR PLANT AND MACHINERY
NCH Europe has introduced a calcium sulfonate based lubricating grease. K Nate is designed to protect bearings and axles from the adverse effects of friction, heat, water damage and pressure. The blend of additives and tackifiers means the lubricant is highly effective across industrial sectors such as mining, construction, paper and pulp, steel mills and automotive manufacture, marine and even agriculture. When subjected to repeated heavy shock loads, the grease stays in place, resists excessive wear

and has a weld load in excess of 800kg on a four ball machine. It also has a melting point of over 290˚C, so can effectively protect the components it is lubricating from the adverse effects of excessive heat while retaining its lubricating properties. In addition, K Nate’s calcium sulfonate base is naturally water resistant, so it scores 0.5% in a water washout test and continues to perform unaffected by the introduction of moisture.
