ABSTRACT:
A tubular stator capable of creating a magnetic field having both linear and rotary components comprises a tubular magnetic frame formed from longitudinal magnetic elements which are angularly spaced. The magnetic elements have teeth which extend radially inwardly. Circular induction coils are disposed between the teeth and undulating coils are disposed longitudinally between the magnetic elements. A magnetic sleeve surrounds the magnetic frame.
An electric motor comprises a cylindrical rotor mounted within the tubular stator so as to be rotatable and translatable.
