A unique magnetic arrangement in which the magnetic forces acting on the rotor are in the direction of motion. This sets the LL Motor apart from conventional electric machines. The data has shown that the Linear Labs (LL) configuration is capable of producing nearly 100% more torque and continuous power than its commercial counterparts within the same frame size and geometrical envelope.
With virtually no end windings, the LL machine allows for reduced copper losses. The data shows that when applying the same frame size as used in commercially available propulsion units, a significantly higher efficiency (especially at the low speed region) can be achieved. This can lead to substantial reduction in onboard energy storage requirements or an extended driving range using the existing commercial Energy Storage System (ESS).
Our data indicates that the continuous and peak power density of the LL motor using standard cooling can exceed 7.0 kW/kg at base speed of 3000 rpm. This is a major accomplishment by an electric motor which clearly supersedes other commercially available electric propulsion units.
Cost & Compactness
The LL motors use the same inverter as conventional electric propulsion drives and operate at lower dc link voltage which allows for smaller dc link capacitor and reduced switch ratings. This results in a more compact and low cost power electronic converter at the required power ratings used in commercial propulsion units.
A unique advantage of the Linear Labs Technology in terms of maintaining high efficiency and high electro-mechanical energy conversion efficiency, where the concentrated windings of the stator results in significant savings of material and reduced copper losses as compared to conventional ac windings, which typically contain large end windings that make no contribution to torque or output.
Variable Speed Applications
The LL Technology with its low noise and low cost power electronics makes it an ideal candidate for variable speed applications such as pumps and compressors, traction, and high speed actuators.
The radial forces in the LL machine are smaller than their commercial counterparts and produce very limited torque pulsation, which provides a very quiet motor drive system.
The Linear Labs motor compared to its commercial counterpart of the same size delivers twice the torque and power. As shown in the graph, the LL design delivers much higher efficiency starting at low speeds and continuing throughout the speed range when compared. This results in energy savings that translates into more driving range on a single battery charge.
The Linear Labs motor is characterized by two main attributes; (1) very high torque starting at low speeds, and (2) high efficiency throughout the speed range.
These attributes can eliminate the need for gear reduction in many applications.
