Is Dura-Trac Technology Disruptive?

Dura-Trac Disrupter Why Dura-Trac Disruptive

■ Optimizes motor performance over broad range of situations

■ Creates “mechanical” electric motor

■ Can be retrofit to existing PM motors

■ Reduces PM motor assembly time/cost

■ Increases PM motor life

■ Works with large/small PM motors


Disruptive Technology #1Axial Field Weakening of Rotor

Current Motors

■ Physics limits PM motor performance

■ Wide dynamic speed range may require transmission

■ Extending speed range electronically has performance penalties

Dura-Trac Technology Motor designed for MAX torque…and

Rotor field reduced for added speed

Functions as a magnetic CVT

Full decoupling for wind, hybrid uses


Disruptive Technology #2Stator-Tooth Construction

Current Construction■ Conventional stator construction

limits wire and coil optimization

■ Results in a higher resistance and inductance winding

Dura-Trac Technology Separate stator tooth stack for

optimum winding

Increases ROI by lowering cost and lowering assembly time


Disruptive Technology #3Stator Winding

Current Windings

■ Coil wire size and resistance dictated by stator-tooth gap

■ Design forces higher resistance and reduces efficiency

Dura-Trac Technology


Wire and copper fill optimized – not

limited by slot width

Form wound coil helps assembly

Increases motor efficiency/output

Disruptive Technology #4PM Motors Magnet Assembly

Current Assembly■ Assembling rotor into stator

involves very high forces

■ Hydraulics and massive fixtures required for production

■ Service problem: field bearing change often not possible

■ Result: much higher life cycle costs

Dura-Trac Technology Motor assembled with rotor disengaged

eliminating high-cost equipment

Optimizes DFM PM motor assembly

Service: easy field bearing change

Result: longer life and lower OpEx


Disruptive Technology #5Field Replacement PM Main Bearings

Current Technology

■ PM bearing failure requires:

– Motor removed from housing

– Repair at specialized facility

– High cost; long repair time

■ Reasons preventing field repair

– Motor design results in extreme magnetic forces

– High force requires special equipment to overcome

Dura-Trac PM Technology


Dura-Trac design

Allows full rotor decoupling

Decoupling eliminates magnetic

forces

Bearings replaced in field

Benefits to user:

Lower service costs

Increased up time

Longer motor life

Higher ROI

Disruptive Technology #6Dura-Trac Retrofit of Existing Motors!

■ Existing stator designs can add Dura-Trac shifting technology

■ Existing PM rotors can add splined shaft for field weakening

■ Changes result in increased speed, torque and efficiency.

Micro-Utility usingVertical Axis Wind Generators

Vertical vs Horizontal

■ Vertical smaller footprint

■ Lower cost

■ Opportunity for Micro-Utility

– No expensive grid infrastructure for delivery

– Horizontal generators require grid to operate

– Store energy in battery pack

– Can combine with solar

Vertical as “Micro-Utility”

■ Remote locations where grid delivery expensive

– National parks

– Indian reservations

– Developing countries, etc.

■ Clusters of homes or small businesses

■ Lower-cost new installations for larger electric utilities


Energy Storage: Lower-Cost Option

Flow Batteries Benefits of Flow Batteries

■ Lower cost

■ Long life

■ Decent energy density

■ Totally recyclable

■ No parasitic drain

■ Constructed as single unit

■ Environmentally benign (almost)
