Hi,

No cordless electric chainsaws :( .

Sounds too good to be true:

Lincoln Jore and Matt Jore came up with the idea of eliminating the wire windings and iron laminations used in conventional motors by embedding copper-etched conductors into a multi-layered printed circuit board to form a stator that works in conjunction with permanent magnets to produce torque in a new type of ironless and wireless motor. They created a special pattern of conductive material, laid out on individual layers of conductive material, and laminated and interconnected to each other to form an efficient, compact, and powerful stator. After six years of development by the Jores and Core Motion, Inc., the technology is now being referred to as CORE™ (Conductor Optimized Rotary Energy). With the highest energy factor per weight of any existing motor or engine, and one-third to one-fifth the size and use of raw materials, CORE™ Technology is designed to replace existing conventional motion devices, motors, and engines. The process for manufacturing a CORE™ stator is the same well-known and mature process used in the construction of printed circuit boards (PCBs) and is, as such, a very reliable and cost-effective production process. Driven largely by the tremendous growth of the computer industry over the past thirty years, PCB manufacturing has evolved into one of the most mature and reliable methods of manufacturing. The proprietary CORE™ stator design allows for elimination of wires and is at the center of a portfolio of very unique and broad patent claims. Core Motion, Inc. has been issued patents, based on US Patent No. 7,109,625, in thirty-two countries covering broad claims relating to the CORE™ technology and several new patents on improvements are pending.

CORE Outdoor Power was founded to commercialize an innovative motor technology into outdoor power products or equipment. The Conductor Optimized Rotary Energy (CORE™) motor is a cutting edge device capable of producing high torque rotary motion at high efficiencies and power densities. This technology was developed by Matt Jore and Lincoln Jore, a father & son team, along with a talented group of engineers at Core Motion, Inc. In brief, CORE™ technology uses a proprietary printed circuit board (PCB) stator to produce high torque rotary motion in a very compact package, without use of the heavy iron used in conventional motor technologies. The proprietary pattern of conductive material in the PCB stator, cooperating with permanent magnet rotors, optimizes the generated efficiency and power. With zero emissions, little noise and torque levels equal to two-cycle engines, CORE™ technology is uniquely poised to disrupt the market for portable outdoor power equipment, especially when combined with the recently developed hybrid power cell that will be used in all CORE Outdoor Power products. This hybrid power cell, which uses lithium based prismatic cells, is capable of storing and delivering unprecedented amounts of power in a very small package. The marriage of these two unique technologies allows for an “environmentally clean” line of products capable of consuming a large portion of the outdoor power equipment market, which has been historically dominated by two-cycle gas engines.
 
Hype.

The fibreglass making up the pcb results in poor "slot utilization". You can see the writer of "Geeks have feelings too" come to the same conclusion in his venture into axial-flux-pcb-stator motor

Edit: you can also read his comparison of tradition windings with the PCB oneshere. These come out about three times better than the PCB windings.
