First products from new CG Drives & AutomationCG Drives & Automation releases

fi rst products since its acquisition

as Emotron by Crompton Greaves

in India. The fi rst new products

from the new formation are the

IP20/21 version of Emotron FDU/

VFX AC drives and the Emotron

TSA soft-starter.

In 2011 Emotron, with its base in

Sweden, Germany and the Nether-

lands, was acquired by Crompton

Greaves, headquartered in India.

By combining its senior technical

expertise in Europe with a strong

corporate organisation in India CG

Drives & Automation has rapidly

expanded its off ering and now

presents the new soft-starters and

AC drives along with CG’s wide

range of electrical motors and

transformers.

New AC drive, Emotron FDU/VFX

in IP20/21 version up to 132 kW.

The new IP20/21 series of drives

from CG targets users of cabinet

or wall mounted AC drives and is

based on the range of IP54

units, Emotron FDU and Emotron

VFX.

The softstarter Emotron TSA is the

fi rst in a new line of CG high

performance softstarters. It

complements the company’s MSF

line of heavy duty fully solid state

soft-starters and off ers integrated

by-pass contactors, soft torque

starting, intelligent load moni-

toring and functions for smart

stops, including braking capability.

The company claims that by

developing the Emotron TSA

range, CG has taken a major step

towards the ideal motor controller

for applications where variable

speed is not required.

Sensor survives extreme ambient temperature testOne of Zettlex’s customers, a

UK-based scientifi c research

company, has successfully

performed tests on an IncOder

sensor in extremely low ambient

temperatures down to -100°C.

Standard IncOders are rated by

Zettlex to operate at temperatures

down to -40°C.

Zettlex IncOders use an inductive

technique and may be considered

as inductive encoders. The

company says that the sensors are

suitable for harsh environments

such as industrial, military and

aerospace equipment – where

electrical contacts, optical or

capacitive devices are

likely to prove unreliable

or pancake resolvers

are too expensive.

“We’re not surprised to

hear from one of

our customers

that an IncOder is operating

successfully below the rated

ambient temperature of minus

40°C, as we know it is such a

robust technology. However, we

were a little shocked to discover

that the IncOder withstood such

an extremely cold environment

down to minus 100 °C. In the past,

we’ve custom engineered

IncOders that can operate down

to minus 65°C, but this recent

discovery has exceeded everyone’s

expectations and again proves just

how robust and reliable the

IncOder actually is.”

Zettlex IncOders are non-contact, absolute angle measuring devices.

Deep groove ball bearing reduces friction by 30%Bearing manufacturer SKF has

launched the SKF sealed energy

effi cient deep groove ball bearing

which, it claims, reduces friction

by more than 30% compared to

the SKF Explorer sealed DGBB.

The new feature, compared with

the previously launched E2

performance class of bearings, is

the addition of a seal that

provides minimal interference

between the inner ring and seal

lip without compromising the

performance of the sealing ability.

For a typical textile machine

running 8000 hours per year

equipped with 200 sealed E2

DGBBs, the reduction is estimated

to 11 310 kWh annually. This

reduction translates into a CO2

saving of 8,5 tonnes per year

according to world power grid mix

CO2 factor of 0.749 kg CO2e/kWh.

The bearing is suitable for applica-

tions in many industries, ranging

from electric motors and two

wheelers to industrial conveyors

and water pumps. The product is

included in the SKF BeyondZero

portfolio.

The SKF Sealed Energy Effi cient

deep groove ball bearing is

available in diff erent sizes up to

52 mm outer diameter.
