Above-mentioned DC adds energy motor operation principle as shown in Fig. 8～9: when the p-m rotor of motor is in initial 0 degree of position Putting when starting working, three groups of commutating brushes 20 are energized with three-phase windings the most simultaneously, and electric current conversion latus rectum is: DC source → lead Electricity brush → conducting ring → commutation semi-ring → commutating brush → three-phase windings → collection magnetic core → permanent magnetism add energy → p-m rotor → Mechanical energy exports；Owing to commutation semi-ring and three groups of commutating brush locations when circular contact are different, cause three-phase windings The sense of current controlled is also the most different, so the magnetic direction of collection magnetic core is different, and the produced suction to p-m rotor, repulsion Designing defined just, they drive the two poles of the earth rotor to move in the direction of the clock respectively, permanent magnetism in the angle of 0 degree～60 degree Power-increasing device is under " positive flux field " state, permanent magnetism and electromagnetism superposition, and couples magnetic flux increases, and p-m rotor magnetic is made by collection magnetic core 5 Firmly strengthen, play permanent magnetism and add and can act on；Otherwise when permanent magnetism power-increasing device is under " counter magnetic field " state, collection magnetic core 5 is to internal layer P-m rotor only plays the effect of electromagnetic force, and the effect of stator permanent magnet is blocked in outer layer, " positive and negative " of this two circulations simultaneously Magnetic field jointly acts on rotor and rotates；When going to 60 degree, commutator assembly sequentially enters next phase place, and rotor continues to rotate, defeated Go out power, such iterative cycles, motor continuous firing.

Machinery (the having brush) DC that controls adds and can be mainly characterized by energy-conservation, low cost, is applicable to drive class electricity by motor Machine.

DC disclosed in this utility model adds energy motor, mainly by rotor permanent magnet and permanent magnetism power-increasing device stator poles Three level (ternary) energy resource structure compositions of assembly, when p-m rotor starts to rotate, diverter is powered to permanent magnetism power-increasing device, collection Magnetic core winding excitation, produces electromagnetism and permanent magnetic overlapped couples magnetic flux, jointly acts on p-m rotor and rotates, and synthesis is converted to Mechanical energy, completes permanent magnetism in this electromagnetic energy transformation process simultaneously and adds energy, the utilization rate of permanent magnetism energy is greatly improved； It can electric machine structure be ternary that DC adds, and principle is two circulations, and the technology adding energy with permanent magnetism utilizes permanent magnetism energy, and feature is efficient Energy-conservation, mechanism is relatively easy, is a kind of New-type electric machine.

Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, this utility model is also Have various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model Claimed scope is defined by appending claims and equivalent thereof.
