Description
Technical field
It is especially a kind of for motor temperature and load test the present invention relates to motor product testing field
Load device.
Background technique
In the temperature rise and load test of motor, need that a kind of device is selected to apply to motor to load, and this negative
It carries continuous, steady adjustable.Apply there are many ways to loading to motor at present, one is utilizing magnetic powder viscous motion device, it is general this
Kind of loading method is suitable for the application for being applied to need frequent start-stop, commutation, and the temperature rise load test time of motor compared with
Long, low-power machine is also required to more than 3 hours；Revolving speed is higher, and general synchronous rotational speed is 3000r/min or 1500r/min, this
So that produce, the heat that accumulates it is more, to directly cause in the temperature on magnetic powder brake whole (each component and surface)
It rises；One is dragging ac motors, and this mode needs complicated feedback control system, to change the frequency of load motor
Rate, investment is bigger, and general enterprise laboratory is difficult have enough investments；One is dragging dc motor, this modes
Exciter Sets, armature circuit resistance adjustment and energy feedback are needed, system complex, investment is big, and direct current generator is in high revolving speed
The maintenance and maintenance of lower brush and commutator frequently, load difficult disadvantage and are also difficult to overcome in the case where the slow-speed of revolution.
Summary of the invention
The purpose of the present invention aiming at deficiency of the prior art, and provides a kind of motor load device
Technical solution applies to motor when the program can be applied to testing laboratory to motor temperature and load test and loads,
It is particularly suitable for the small-scale motor experiment room of enterprise；When test, by two kinds of resistance value that adjust exciting current and turntable
Means apply convenient for motor to be loaded, and is expanded adjustable range, is improved degree of regulation and stability.
This programme is achieved by the following technical measures: a kind of motor load device, including motor, torque turn
Fast sensor, characteristics of this program are: motor drives a turntable by torque rotary speed sensor, is provided in the two sides of turntable
Opposite polarity electromagnetic pole disk, the turntable are connected with a variable rheostat.

The beneficial effect of this programme can according to the description of the above program, due to there is electromagnetic pole disk in this scenario,
Turntable can be given to provide magnetic field, when motor rotation, drive turntable rotation, turntable cutting magnetic induction line generates electromotive force, Jin Erqi
To certain resistance, that is, play the role of load；Turntable is pressed into contact with a runner, draws a conducting wire, then from the central position
An other conducting wire is drawn, variable rheostat is connected to, to adjust the resistance value of turntable current loop, to adjust the negative of motor
It carries；There is flabellum shape spoke on turntable, the effect of spoke is that cutting magnetic line is in magnetic field to generate electromotive force, another effect
Be heat dissipation, by the rotation of flabellum shape spoke, thus take away electric current tide over the heat of the heat, ferromagnetic material that are generated when spoke with
And the heat of enameled wire, to realize that itself is cooled down；It is provided with the pipelined channel for water cooling between winding conductor, may be implemented
Water cooling, and the temperature rise of equipment is further decreased, the load capability of equipment is improved, the service life of equipment is extended；Ferromagnetic core includes
Multiple silicon steel sheets laminated, reduce eddy-current loss.It can be seen that the utility model is compared with prior art, there is substance
Feature and progress, beneficial effects of its implementation are also obvious.
