Abstract

A motor which has an improved energy efficiency, is excellent in practical use and has a generator function at the same time. The motor is provided with a basic factor 15 having working surfaces 55a and 55c on both sides thereof, respectively, and movable members 57 made of a magnetic material and arranged opposite to the working surfaces, respectively. Further, the basic factor 15 is provided with an electromagnet element 17 and permanent magnets 19 arranged on both sides thereof through contact surfaces, respectively, and the working surfaces and the contact surfaces are held opposite to each other through the permanent magnets 19, respectively.

Claims

1. A motor using a basic factor having working surfaces on both sides thereof and attraction members made of a magnetic material, and capable of being held opposite to the working surfaces so as to be attracted to the working surfaces, respectively, said basic factor comprising an electromagnet element and permanent magnet elements arranged on both sides of said electromagnet element through contact surfaces, respectively, said electromagnet element comprising a magnetic core having an H-shaped section and a coil wound around the magnetic core, said permanent magnet element being provided at both end portions of said H-shaped section and comprising a permanent magnet and magnetic members sandwiching said permanent magnet therebetween, wherein said permanent magnet has a length shorter than a distance between said end portions of said H-shaped section, said working surfaces and said contact surfaces being held opposite to each other through said permanent magnet elements on both sides of said electromagnet element.

2. The motor as claimed in claim 1, wherein when a DC pulsating current is applied to said electromagnet element, the working surfaces of said basic factor are driven by attracting said attraction members only for a period of time during which said pulsating current is continuously applied.

3. The motor as claimed in claim 2, wherein a plurality of said attraction members are linearly arranged in spaced apart relationships with one another to thereby form a linear motor.

4. The motor as claimed in claim 3, wherein a central member is formed by overlapping a plurality of said basic factors at a first pitch interval, a plurality of said attraction members being arranged on both sides of said central member at a second pitch interval along the overlapping direction of said basic factors with said first pitch interval being made larger than said second pitch interval.

5. The motor as claimed in claim 4, wherein said central member constitutes a movable element, and said attraction members constitute a stator.

6. The motor as claimed in claim 2, wherein a plurality of said attraction members are arranged concentrically on a circle to constitute a stator while said basic factor constitutes a rotor rotatable about a central axis.

7. The motor as claimed in claim 6, wherein said basic factor has said working surfaces respectively arranged at quadrant positions of a circle drawn about said central axis.

8. The motor according to claim 7, wherein said rotor comprises a plurality of said basic factors arranged in series keeping central axes thereof uniform in position in the direction of said central axis.
