INVERTER DRIVE HELPS SPEED UP THE DRILLING PROCESS
HOW LIGHTWEIGHT MOTORS CAN HELP ADD A SENSE OF LUXURY TO CARS
Many vehicle manufacturers are now looking to integrate in-car entertainment systems that feature large, high- resolution, flat screens into the overall interior design, rather than adding them on as a feature. For these, they often opt for motorised screens and displays, so they can be hidden from view for aesthetic or safety purposes. The automated opening and closing mechanisms, however, need to last for years with minimal maintenance, so a quality motorised drive system is therefore needed. With space limited, compact and lightweight drive
solutions that offer superior torque while coping with the forces associated with the opening and closing of the monitors, need to be chosen. These also need to be capable of withstanding vibrations and varying temperatures. EMS is the sole UK supplier of FAULHABER motors and has
in-house bespoke design and manufacturing capabilities. For one automotive application, the company developed and supplied the drive unit for a rotating multimedia display interface, which maximised the potential screen size for the minimal space across the vehicle’s interior. These same systems can also be adapted and integrated
into other motorised interior vehicle features, such as electric seat positioning systems, motorised sunroof shades, wing mirror adjustors and even automatic passenger assistance steps. All of these features not only add a sense of luxury to the vehicle, but the standard of the motor system used adds to the customer experience, the company explains.

Larvae from the Black Tiger Fly is produced at Entofood and Veolia’s bioconversion plant in Malaysia. The flies feed on waste food made up of unused or undervalued organic waste before producing the larvae, which is used as protein in the rapidly expanding global aquaculture and agriculture industries. Around 1kg of eggs from the flies produces six metric tons of protein in 10 days that is used by fish farms, poultry and pig producers, among others. It’s estimated that 10% of the protein market could come from insects by 2040. Ventilation fans are used to
maintain an even environment for the flies to feed on the waste before laying the larvae, but the drives at the plant were not matching with the motor current of the fans, causing frequent tripping. This resulted in fluctuations in the facility’s environment, making production less efficient. To overcome the problem, Invertek Drives
Malaysia and DSC Engineering installed 58 Size 2 Optidrive E3 IP66 VFDs. These were commissioned

with 4kW output at 9.5 Amps to match the fans’ motor current. Not only did these prevent tripping, but they provided great control of the fan speed. With their IP66/NEMA 4X rated VFD enclosure,
these are also capable of withstanding washdowns, waste products and flies. The Optistick Smart, which uses
NFC and Bluetooth technology, was used with the Optitools Mobile app to commission and to duplicate parameters on the 58 drives. The growing market for such
animal and fish food protein will mean an increase in such facilities, relying on VFDs to control fans for ambient environments. “The prospects are promising:
aquaculture provides half of the fish consumed worldwide. Bioconversion will mean that cultivated fish do not have to be fed with other fish or any
protein grown to the detriment of food crops or forests,” said a Veolia Biodiversity statement.

DRIVE SOLUTIONS FOR PLASTIC EXTRUDERS
In addition to its MAXXDRIVE industrial gear units, NORD DRIVESYSTEMS’ extruder- type drive solutions are proving beneficial for the plastics industry. The extruder
option can be customised to the customer’s shaft and matched to their demands with several bearing variants. This gives plant constructors, manufacturers and processors of plastics the opportunity to develop safe and highly reliable drive units that are particularly versatile. Extruder types are available for the MAXXDRIVE industrial gear units in sizes five to 11 with rated torques from 15 up to 75kNm.

With Tool Drives’ modern high-speed drilling units, it takes just 17 seconds to drill 100 holes 6mm in diameter and depth in a coated composite wood panel, with the greatest precision. During this operation, the drill reaches speeds of up to 18,000 revolutions per minute, even though it has to adapt its power to the different layers and characteristics of the panel. With finished quality of the drilled holes what really counts,
the company examined the drilling process very closely. So, they developed a special feed screw, and used motors and motion controllers with enough power to apply maximum forces, while still allowing a high degree of fine control. To achieve the desired result, the inverter drive for the high- power drill drive needed to be able to supply an output frequency of 1,000Hz but, at the same time, fine control of the PM motor used for the drill unit’s drive was essential. Turning to YASKAWA, the company selected the A1000 inverter drive which supplies
the required output frequency of 1,000Hz, provides 1.5kW of power with open-loop vector control and delivers up to 150% of its rated output for short bursts. Of benefit to Tool Drives, the company offers worldwide support and an extensive
product range, enabling it to be used as a one-stop shop. The MP series’ all-in-one machine controller, for example, is a single platform that combines all the functions required for the machine’s processes, including motion and PLC functionality, inputs/outputs, sequential logic and process algorithms. The controller integration saves on system costs, reduces the amount of space the unit takes up in the control cabinet and standardises the programming. The scalable hardware for motion applications is suitable for use in complex applications with up to 64 axes. With the high-speed drilling unit, the drilled hole specifications were achieved
using Yaskawa’s tried-and-tested G-code. The MotionWorks IEC software and the Yaskawa toolbox feature make programming the machine controller easier, combining the five programming options ladder diagram (LD), function block diagram (FBD), structured text, instruction list (IL) and sequential function chart in one developer package. In addition, these controllers also have a built-in web server and are compatible with international network protocols such as Profibus and Ethernet.
