Cage Induction Rotors
~ High Performance
~ Rugged Reliability
~ Small Footprint
This well proven industry work horse
is available in a number of different
designs from low voltage fractional
horse power up to 300 ton machines.
Designs are offered with copper or
copper alloy, or for smaller machines,
both copper and fabricated aluminum.
Each machine is optimized to suit
specific needs by modifying the stator
and stator winding as well as the rotor
cage bar profiles and materials. In this
way a design can be optimized to give
the right starting torque capability,
ensuring high efficiency and an
optimized power factor.
With our ability to optimize motor
designs for use with variable frequency
drives, cage motors are now being
supplied for applications never
previously considered. GE has supplied
very high speed cage induction motors
that eliminate the need for gearboxes
(some of which operate at 20,000 rpm!)
Our mine hoist technology supplies
shaft-less induction motors in excess of
100 tons.
Aluminum Cage Construction
> Low mass bars and end-rings reduce
centrifugal force.
Copper Cage Construction
> This design provides greater capability
for starting high inertia loads.
> High efficiency helping to reduce
CO
2
emissions.
