Description
Technical field
The present invention relates to a kind of rotating shaft mechanical torque detection technique field, start the special firing test device of magneto particularly to a kind of high-power frequency conversion.
Background technology
As far back as early in the twentieth century, the first permanent magnet material aluminum nickel cobalt of industrial circle is produced, thus opening the development course of permanent magnet synchronous electric machine technology.But Al-Ni-Co permanent magnet material magnetic energy product is little, limit the development of permanent magnet synchronous electric machine technology, until rare earth material comes out, just make permagnetic synchronous motor grow up gradually.The eighties in 20th century, along with the appearance of NdFeB material and power electronics and microelectronic development, permagnetic synchronous motor cost is greatly lowered, and controls to be more easy to realization.The nineties in 20th century is so far, permanent magnet material, power electronics and microelectronics and the technology such as designing permanent-magnet synchronous motor and exploitation have had marked improvement, so that the application of magneto is more extensive, have become as the first-selected motor of drive system, represent the direction of 21 century motor driven systems development.High-power slow-revving permagnetic synchronous motor is a lot all applied in as constant torque load occasions such as ribbon conveyers, require that motor all has constant torque characteristic in whole frequency range, particularly ribbon conveyer, requirement has under nominal load, from the ability that zero-speed starts, this require motor startup stage there is 1.5-2 times of nominal load fan-out capability, but now but without the assay device testing this electric motor starting ability in industry, the firing test special purpose device of present invention invention well solves the test of the heavy load starting ability of variable frequency starting magneto.
Summary of the invention
The technical problem to be solved is: the invention provides the high-power frequency conversion of a kind of heavy load starting ability testing variable frequency starting magneto and starts the special firing test device of magneto.
The technical solution adopted in the present invention is: a kind of high-power frequency conversion starts the special firing test device of magneto, include tested magneto and for installing the motor rack of magneto, also include brakes, be located at brakes and be provided with connection axle, described magneto is provided with motor shaft, described motor shaft is connected by shaft coupling with being connected axle, and described shaft joint is provided with torque sensor.
Adopt technique scheme, the connection axle shaft coupling of motor shaft and brakes is bound up, at motor shaft, torque sensor is installed simultaneously, detection motor output torque, then brakes band-type brake is allowed, starting magneto, observe whether motor output torque reaches designing requirement on torque sensor, this mode well solves the startup aptitude tests of magneto.
The present invention is further arranged to: described brakes is disk brake, the other end that described connection axle is connected with disk brake is connected with shaft coupling by band set of books flange, and described shaft coupling is connected the other end of axle one end and is connected with motor shaft by the second band set of books flange.
Adopt technique scheme, shaft coupling by band set of books flange and the second band set of books flange respectively with is connected axle and motor shaft connects, mounting structure simply, firmly installs.
The present invention is further set to: also including torque sensor support, described torque sensor one end is sheathed on motor shaft, and the other end and torque sensor support removably connect.
Adopting technique scheme, torque sensor support is used for supporting torque sensor and torque sensor with torque sensor support removably connects, and so arranges and torque sensor can be made to facilitate when taking off from motor shaft dismantle.
The present invention is further set to: described torque sensor and torque sensor support are removably connected by screw.
Adopting technique scheme, the connected mode of screw is relatively simple, and installation is connected firmly, and dismounting and installation are all convenient.
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
