Definitely, Maybe.....
Gary,
The best arrangements (for the attraction motors discussed in this thread) use coils with large gauge wire, low number of turns, high current, low voltage pulses. The speed of the motor is regulated by the inductive rise-time of the coils. The faster the magnetic field can appear in the coils, the stronger it can pull on the rotor at the beginning of the power stroke. Producing high levels of tangential force on the rotor is the key to producing torque in the motor. The efficiency of the electrical recovery is regulated by the change of reluctance in the air-gap between the "turn on point" and the "turn off point", as the rotor is attracted into alignment with the stator pole. As the air-gap closes, the reluctance of the circuit drops. As this occurs, the energy stored in the magnetic field drops to a lower state, meaning that there is less energy to recover when the field is discharged. Still, 70% electrical recovery has been demonstrated, which is approaching the reasonable limit in a variable reluctance arrangement.
The need for very small air-gaps and rapid switching of high current pulses has turned out to be a formidable project for the home model builders. Still, this thread does contain a treasure trove of data and principles on how an advanced motor can operate.
There are a number of very important implications that can be derived from a careful analysis of this situation. These include motors that will run on pure Reactive Power, as well as motors that will run at full power on nothing more than the magnetizing current.
For those that can think it through, there is a treasure beyond your wildest dreams.

Hi Peter,
Do you think it would be better to have 4 stators in series instead of 2 like Jetijs has or would it somehow hinder the performance of the motor or the recovery electric.Thx for any input

a few questions: what was the cop on jetijs attraction motor and what design would you now go with jetijs, hope you don t mind sharing ,would like to build one seek + explore obviously typing and spelling are somewhat challenged here but i do promise to work on all.Also does anyone have any info on robert adams thermo motor thanks bart
