Intellectual Property Protection
CALNETIX Proprietary Technology brings unique, cost effective
solutions that are not available elsewhere in the marketplace!
The technology in Calnetix’s high speed motors, generators,
and magnetic bearing products are protected through component
and system level patents. Calnetix patented technology offers
the following benefits to customer applications:
- Core and system level technologies are in scalable configurations
for addressing a broad market including size ranges from
1KW to 20MW
- Configurations and construction offer performance and
cost advantages
- Core patented products provide significant advantages
for new product introduction
The company has filed system level patents in the United
States, as well as internationally, on various systems. These
system level patents, combined with design and manufacturing
know-how and proprietary processes, make it extremely difficult
and expensive for any competitor to duplicate Calnetix’s
technology.
Calnetix high speed motor, generator and magnetic bearing
construction is also protected by proprietary design and manufacturing
methods. The design of each system is conducted with analysis
codes that have been developed in-house and are based on years
of experience. Calnetix possesses unique design and manufacturing
processes which include the following:
- Steel sleeving for high speed two pole rotor topology
- Proprietary process for graphite sleeving of high speed
rotor topology.
- Stator winding and end turn forming for low loss and
high power density
- Magnetic bearing integration and assembly
Calnetix possesses proprietary software that is used both
in the development of the company’s products, as well
as in the products themselves. A sampling of the software
includes:
- Design and analysis software
- In-house developed analytical tools for the design
of permanent magnet motors, generators and magnetic bearing
actuators.
- In-house developed rotordynamic analysis software which
incorporates magnetic bearing performance characteristics
to predict performance and system stability in all operating
conditions.
- High speed rotor stress analysis for sleeving fit and
bearing component fittings.
- Complete thermal analysis of the rotating components.
- Operational software
- Magnetic bearing control system software for high
speed, high performance magnetic bearings which includes
open loop compensation for no-vibration and low bearing
loads.
- Motor control software for sensored and sensorless
motor drives for high speed permanent magnet machines.
This line of motor drives which is specifically for
high speed permanent magnet systems offers higher efficiencies.
- Testing software
- Diagnostics software for power and energy measurement
of high performance systems.
- Graphical user interface for magnetic bearing performance
and interface, allowing for updating of control system
and review of performance data.
- Control system interface for command and communication
between the facility, power electronics, and magnetic
bearings.
