DRIVES, CONTROLS & TRANSMISSIONS FEATURE
MOTOR DELIVERS HIGH TORQUE AT LOW SPEEDS Harmonic Drive UK has launched TorkDrive, a multi-pole direct-drive torque motor designed for applications including rotary transfer machines, rotary tables, machining centres, roller and cylinder drives as well as positioning and handling axes. The multi-pole design allows the drive to transmit high torque at low to medium rotational speeds. TorkDrive has been developed to provide high dynamic response, precision and system rigidity in industries from robotics and handling to machine tools, packaging and the food and beverage sector. The range is available in five sizes offering a maximum torque from 19 to 600 Nm. Units can be customised for integrated drive solutions and are available in kit form where the stator and rotor are delivered as individual components without housing. This provides a compact solution for direct integration into machine design. “TorkDrive operates like a synchronous servo motor because the rotor is fitted with permanent magnets and the stator houses the windings,” explains managing director Graham Mackrell. “The main difference that really sets it apart is that it has a large number of pole pairs in the stator and rotor. These single pole windings are rated for 400 VAC; TorkDrive delivers maximum torque at
low speeds, exceptionally low noise levels and minimal wear for the lifetime of the drive. Integrated temperature sensors ensure that the motor is protected from overheating. In addition to sensors the standard version is designed for water cooling so that users can take advantage of a higher power output while keeping heat transfer to a minimum.” A large hollowshaft in the centre of the
unit allows users to pass through cabling, supply lines, optical lasers and other services while minimising unit footprint.

ATEX-COMPLIANT GEARED MOTORS
WEG has launched ATEX-compliant geared motors to help companies operating in hazardous areas improve reliability while reducing energy consumption and operating costs. Combining robust gear units from
TorkDrive is designed for applications including rotary transfer machines, rotary tables, machining centres, roller and cylinder drives as well as positioning and handling axes
WEG’s subsidiary WATT Drive with energy-efficient W22X motors - available in frame sizes from IEC 71 to IEC 800 and energy efficiency classes up to IE4 - the range is suitable for harsh processing applications in most industries worldwide. Watt Drive’s full range of gear units can be combined with W22X motors using IEC adapters. All gear ratios in the MAS gear unit product line and all drive and flange options are possible including solid shaft with flange and hollow shaft with shrink disc. The gear units are robust and reliable
as they are fully compliant with ATEX standards and feature impact-resistant hollow-shaft or shrink-disc covers. Furthermore, all bolts are secured to prevent accidental loosening and heavy-duty high temperature-resistant oils are used.

UK launch of Rittal’s Innovative Blue e+ Cooling System
The Blue e+ is a major advance for the sector and represents a quantum leap forward in terms of efficiency and cost effective operation. As well as being far more energy efficient than existing cooling solutions, Blue e+ systems use state of the art technologies, packaged in a unique manner, to also deliver greater flexibility, safety and ease of handling. Key to the efficacy of the Blue e+ is Rittal’s innovative patented hybrid system. “The hybrid system increases energy efficiency significantly,” says Steffen Wagner, Rittal’s Head of Climate Control Product Management. “It uses a clever combination of a compressor cooling device and a heat pipe to take maximum advantage of passive cooling. The compressor only kicks in when passive cooling becomes insufficient to meet demand,”he adds.

From Ice Cold to Burning Hot
s of the end of September, the new Temperature Sensor OptoTemp has expanded wenglor’s product portfolio in the field of Photoelectronic Sensors.
A The high-performance sensor measures
temperatures within a range of -25 to 350° C on the basis of infrared radiation emitted by the object, regardless of the material it’s made of and its state of aggregation. And thus wenglor is once again demonstrating innovative market competence in the area of optical sensor technology. The measurement of infrared radiation is quick and contactless, and the object itself is not influenced in any way. The temperature of a great variety of objects can thus be reliably measured, regardless of the material they’re made from and their state of aggregation. The sensor measures temperature with a spectral sensitivity of 8 to 14 m within a measuring range of -25 to 350°C. The measured value appears at the integrated, intuitively operable display and is read out via the outputs or the RS-232 port.
