The resulting motor construction is what conventional technologists would describe as a wave wound axial air gap brushed DC motor. The performance, however, is far from conventional. When compared to an equivalent wire wound DC motor capable of producing similar torque, several advantages are obvious. The first is that the Etek motor uses one-tenth the steel and one-half the copper as is used in a conventional DC motor. The second advantage is that the Briggs & Stratton motor is one-half the size of a competitive motor. While many designers today think of the motor and controller late in the design cycle, Briggs & Stratton believes that some designers may want to start with the company’s motor size and design around it.

Possibly one of the most significant performance features of the Etek motor is efficiency. While demonstrating high efficiencies under no or small loads, conventional DC motors experience a dramatic drop in efficiency (as low as 70 percent are not uncommon) as they are loaded down. This simply means that nearly a third of the valuable energy in the on-board batteries is going toward producing heat and other unwanted power rather than motion. The Etek motor technology does not use battery energy to produce its electric field in the stator. This is done by the neodymium permanent magnets. The use of copper bus bars gives the motor an extremely low internal resistance, which results in greatly reduced losses.
