Title:
MOTOR
Document Type and Number:
Japanese Patent JPH037057
Kind Code:
A
Abstract:
PURPOSE: To obtain a motor which can operate correctly even if the supply voltage and the mechanical output increase by realizing a homopolar field electric machine requiring no commutator part. CONSTITUTION: Inductor field generated from a permanent magnet 28 runs from one pole to the other pole. Since these poles are set in tandem in the axial direction, magnetic lines of force from one pole are directed radially over the entire circumference and pass through an air gap 24 into a stator 22 where they touch the magnetic part of an armature. Subsequently, the lines of magnetic force are curved in the axial direction according to a tubular shape concentric to the electric machine and further curved radially to match the other pole before being passed again into the rotor 20 while interacting with the corresponding magnetic part. A groove 26 for receiving the magnetic part is set in each juxtaposed disc laminate while extending in parallel with the axis.
