Technical field

The present invention relates to a kind of efficient biserial permanent-magnet speed governors, belong to permanent-magnet speed governor technical field.

Background technique

Permanent-magnet speed governor is that the conductor material in conductor disc cuts the magnetic line of force on permanent magnetic disk, generates nest electric current and forms dislike magnetic Field transmitting torque, conductor disc is driven disc, drives driven disc permanent magnetic disk, the torque of conductor disc and the bigger transmitting of permanent magnetic disk distance Efficiency is lower, and similarly conductor disc and the torque of the nearlyr transmitting of permanent magnetic disk distance are bigger, the effect of speed regulation is realized, while speed regulation Conductor disc can generate a large amount of heat it is necessary to radiate by cooling fin.The structure of existing permanent-magnet speed governor is two and leads Body disc acts on two permanent magnetic disks, and the cooling fin when power is greater than 400KW on existing air-cooled governor can not take away generation Heat is needed using expensive oil cooling or water cooling permanent-magnet speed governor.It is solved for this reason, it may be necessary to design corresponding technical solution and give.

Summary of the invention

The present invention be directed to the shortcomings of the prior art, provide a kind of efficient biserial permanent-magnet speed governor, solve above-mentioned Background technique there are the problem of, meet actual operation requirements.

To solve the above problems, the technical solution used in the present invention is as follows:

A kind of efficient biserial permanent-magnet speed governor, comprising: rack is driven, operating motor is installed in the driving rack, The power output end of the operating motor is equipped with permanent magnet transmission system；

The permanent magnet transmission system includes: the magnetic actuator for being mounted on operating motor power output end, the permanent magnetism Two groups of inner and outer rotors are installed, inner and outer rotors described in two groups include four conductor discs being mounted on magnetic actuator on driver Four permanent magnetic disks used with cooperation conductor disc, inner and outer rotors described in two groups further include that four be mounted on magnetic actuator dissipate Backing.

As an improvement of the above technical solution, inner and outer rotors described in two groups be symmetrical arranged, and inner and outer rotors described in two groups it Between there are the air gaps.

As an improvement of the above technical solution, the cooling fin is mounted at the air gap, and the cooling fin is installed respectively In the outer end of inner and outer rotors.

As an improvement of the above technical solution, the driving shell outside is equipped with triangular support bracket, in the driving rack Side bottom is equipped with triangle reinforcement plate.

Compared with prior art, implementation result of the invention is as follows by the present invention:

The present invention increases by one group of inner and outer rotors, acts on four permanent magnetic disks using four conductor discs, while also there are four disks Cooling fin, heat dissipation capacity also double, and compensate for blank of the 400KW or more without air-cooled governor, air-cooled governor it is cold to oil or Water cooling governor has the characteristics that structure is simple, ground area of standing is small, operation and maintenance is at low cost.
