Abstract

A superconducting engine relates to a superconducting direct-current motor, wherein, the electric motor is composed of a stator, a rotor and a bearing. The rotor is provided with a U-shaped annular groove single-pole magnetic field surrounded by the permanent magnet. The stator is provided with a U-shaped annular groove single-pole magnetic field which is arranged in the rotor and a superconducting armature coil that spaces the permanent magnet of the rotor with a clearance. The superconducting armature coil is immersed in the refrigeration liquid and generates cyclic current in the superconducting armature coil thereby driving the engine to work. The motor has the advantages of no commutator, no electric brush, and no iron loss in stable operation, extraordinary high energy saving rate, extraordinary high efficiency, long service lifetime, easy velocity modulation and broad usage.

Description

technical field [0001] The invention relates to a DC motor, in particular to a superconducting DC motor without commutator, brushless and iron loss. Background technique [0002] DC motors are divided into electromagnetic type and permanent magnet type according to their magnet types. Permanent magnet type without excitation winding has simpler structure, smaller volume, lighter weight, less copper consumption, less loss, high efficiency and more reliability than electromagnetic type, so permanent magnet DC motors are more widely used. However, the existing electromagnetic DC motor has both a commutator and a brush; the existing permanent magnet DC motor either has a commutator, a brush, or both a commutator and a brush; Brushes and commutators affect the service life of existing DC motors. In the existing DC motor, the magnetic poles around the armature are alternately distributed along the circumference, and there is a gap between the adjacent magnetic poles. Because the...
