Induction motor with highest power density in its class
When it comes to technology, there seems to be no denying that smaller is better. The more
advanced the world becomes in its capabilities, the more we rely on technologies to help us
realise our maximum potential. More than ever, heavy industry is experiencing the same pres-
sure to process more without compromising operational performance. Today, GE Power Con-
version announces its latest induction motor leading the way in facing the challenge. With over
one hundred years of experience in developing induction motor technology, the N37 induction
motor is an upgrade to the well-established N3 motor line. It builds on a time-proven design
with cutting-edge mechanics in order to meet heightened customer demands on footprint and
performance. Working to decrease the component weight, GE Power Conversion achieved an
induction motor design with a dramatically increased power per kilogram ratio. At a lower frame
size than conventional induction motors, this compact design translates to space savings and
lower weight, essential both in onshore and offshore applications.The N37 squirrel-cage induc-
tion motors operate at 50 Hz and will soon be available in 60Hz. The N37 is among the most
efficient motors in its class. GE’s solution works to reduce energy waste while simultaneously
reducing the operator’s environmental footprint. “We’re constantly facing tougher demands in
the power conversion industries – customers want products that are simplified, streamlined and
compact but nevertheless meet increasing performance expectations,” said Luc de Camas, product
leader, GE Power Conversion. “GE is responding to this call with the N37, which retains all the
benefits of tried and tested technology but has been adapted to bring increased convenience to
the operator”.The N37 launch marks the first of
GE
Power Conversion’s induction motors to be
standardised for a wide range of industrial applications.

Energy consumption reduced by up to 50 %

Turbo’s advanced new closed loop differential pump (CLDP) servo drive design is simple.
The heart of the unit is an integrated servo pump consisting of a servo motor and an internal gear
pump. Its flow rate is per-fectly matched to the cylinder surfaces of a differential cylinder,” says
Grant Robinson,VoithTurbo vice-president – EMEA Division, Mining and Metals SouthernAfrica.
The unit also includes intelligent control via fieldbus connection, a pressure
limiter, and a small compensating tank. This control system design renders
other components, such as expensive valve engineering, unnecessary.
“Energy losses caused by throttle effects do not occur with the
CLDP.This increases the machine energy savings by up to 50 %,
compared to machinery using conventional drive systems,”
adds Robinson.
