Abstract
The utility model discloses a tester for the starting torque of a permanent magnet motor, wherein a permanent magnet motor shaft is connected with one end of a force transferring lever by a flange plate, another end of the force transferring lever is fixed on a support provided with a pressure sensor, and the pressure sensor is connected with a data processor by a line. After the tester is installed, the permanent magnet motor is electrified at 5 seconds, the stalled permanent magnet motor generates a fluctuant rotating torque, the torque transfers a force onto the pressure sensor through the force transferring lever, the pressure sensor acquires a fluctuant pressure signal and transmits the signal to an signal amplifier, the signal is amplified and is transmitted to the data processor by means of analog-to-digital conversion, the data processor obtains the starting torque of the permanent magnet motor by means of analysis computation, and stores the starting torque, and a test result is displayed on a display screen or printed as required. The tester experimentally testes the starting torque of more than seventy permanent magnet motors, thereby being exact and stable in result.
Description
Technical field
The utility model relates to a kind of torque testing device, especially a kind of magneto detent torque proving installation.
Background technology
The application of magneto has the history of many decades, but on oil pumper only 10 years on probation, and is on probation at oil pumper from 1999, to 2007 through 8 years update, make this motor be tending towards ripe.The power savings of magneto is more and more by everybody approval.Magneto manufacturer is also more and more.Before 2008, do not have the national standard of magneto, do not have industry standard yet.The testing apparatus that does not more have specialty.Therefore, be difficult to the overall quality of thoroughly evaluating magneto.Main cause is that present starting moment proving installation cannot satisfy the fluctuation of magneto in start-up course.Traditional electric motor starting force moment testing device mainly contains following two kinds.
1. directly read the detent torque of motor with electronic weighbridge
Welding a length on the axle sleeve of asynchronous motor 6 is 1 meter steel pipe 7, and other end level is placed on the table top of electronic scale, sees shown in Figure 1.The steel pipe test arm is loaded onto in rotation in a clockwise direction after the empty load of motor energising after the power failure, and the reading of electronic scale is exactly the detent torque of asynchronous motor 6 behind the motor.
2. on the axle of motor, be connected in series torque sensor
Directly on 6 in asynchronous motor, go here and there torque sensor 8, stop operating but load end adopts clamping device 9 to tighten axle, energising back torque sensor 8 is measured dtc signal, and the torque testing device demonstrates staring torque after signal analysis is calculated, and sees Fig. 2.
More than two kinds of sides be adapted to the test of the average detent torque of asynchronous motor, mainly be because the not fluctuation of asynchronous motor detent torque, data stabilization.And magneto is in start-up course, and detent torque is in a fluctuation status, and vibration frequency is 50Hz, so conventional test methods can not be tested the detent torque of magneto.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned prior art, provide a kind of simple in structure, easy to use, the magneto detent torque proving installation that test result is accurate, stable.
For realizing above-mentioned purpose, the utility model adopts following technical proposals:
A kind of magneto detent torque proving installation connects force transferring lever one end through ring flange on the Permanent Magnet and Electric arbor, and the force transferring lever other end is fixed on the support that is provided with pressure transducer, and pressure transducer links to each other with data processing equipment through circuit.
Said force transferring lever is provided with the safeguard protection cover.
Said force transferring lever is a structural I-beam.
Said pressure transducer be arranged at three block plates on the support of lever below below.
Said pressure transducer links to each other with data processor through signal amplifier, A/D modular converter through circuit, is connected with control panel, display and printer on the data processor respectively.
During application, at first, on the Permanent Magnet and Electric arbor, put a ring flange, follow the motor shaft fixing compact, the ring flange of an equal size in the end welding of force transferring lever links together two ring flanges through screw then then
Principle of work: after installing the utility model; Switched on for 5 seconds to magneto; Magneto behind the stall produces the rotating torque of fluctuation, and this moment is delivered to power on the pressure transducer through force transferring lever, and pressure transducer is gathered out the pressure signal of fluctuation and delivered to signal amplifier; Signal is delivered to data processor after amplifying again after analog-to-digital conversion; Data processor is stored through drawing the detent torque of magneto after the analytical calculation then, is presented at as required and perhaps prints test result on the display screen.
Amplifier and pressure transducer adopt high speed device, and every 1ms gathers a pressure signal, that is to say in a sinusoidal cycle image data 20 times, go out the moment oscillogram in the start-up course 5 according to these point-renderings.Consider that the moment that starts beginning is unstable, when calculating average torque, cast out first second data, 4000 data of collection in back 4 seconds are calculated, draw average torque.
This device is crossed the detent torque of more than 70 permanent magnet motor through experimental test, the result accurately, stable.
