Efficient permanent magnet direct current generator

Abstract

The invention provides an efficient permanent magnet direct-current generator. The efficient permanent magnet direct-current generator is composed of a generator and a full-wave rectifier connected with the generator, wherein the generator is composed of a cylindrical rotor and a stator, wherein the cylindrical rotor is filled with permanent magnet cylindrical magnetic materials in the radial direction in an outer stator wound with a coil, and the stator is externally wound with a stator coil. The winding mode of the stator coil is that the coil of the same phase winding can be wound between two adjacent tooth grooves of a single armature tooth and can be wound by crossing a required armature groove according to needs, and the two ends of the stator coil of each phase are connected with a full-wave rectifier. All the south pole and the north pole on the magnetic rotor generate electricity at the same time when the rotor generates electricity and rotates each time, the efficiency and the power of the generator are improved, the defect that the electricity generation efficiency of a traditional generator is reduced is avoided, the utilization rate of a winding coil is improved, and the electricity generation power is increased. The direct-current generator can be widely applied to direct-current generators and extended-range new-energy electric vehicles.

Problems solved by technology

In traditional permanent magnet DC generators, a large number of coils are wound across the armature teeth. For example, most generators with three-phase windings are wound across two armature teeth. In order to increase output power and The utilization rate of winding coils almost always uses the star connection and delta connection of three-phase AC motors. Every time it generates electricity, at least two phase coils flow through them. However, due to the different physical locations of the two phase coils, when the two When a group of coils generates power at the same time, there are often positive and reverse winding currents on the same armature tooth edge, which reduces the power generation efficiency.
