Description
Technical field
The utility model belongs to technical field of measurement and test, refers in particular to for motor speed, torque, the detection of power, efficiency
Device.
Background technology
With the iterative method of industrial automation, the pattern and species of motor are more and more.And for motor, turn
The parameters such as speed, torque, power, efficiency are most important, are producing and will measured in detection process.
The detection method of general motor has three kinds：(1) the additional constant load of motor is given；(2) motor inertia load is utilized；
(3) modeled between motor and other parameters for being easier to measure to investigate both relations.These three detection methods have necessarily
The drawbacks of：(1) motor applied load is given, it is either mechanical or electronics, motor and load will be coupled, this ten
Divide time-consuming；And due to the limitation of applied load, test speed and torque all can not be very big, but test torque again cannot be very
It is small, because with the presence of a very big applied load error, such as shaft joint error, load inertia error itself, so as to determine
The method cannot be used for the test of small and large-size machine, it more difficult to realize detection and the producing line full inspection of large quantities of motors.(2) utilize
Although the test of motor inertia load is quick, accurate, precondition is must accurately to test out the rotary inertia and electricity of motor
The angular acceleration of machine boost phase.(3) modeled between motor and other parameters for being easier to measure to investigate both relations,
It is a kind of round-about way, it is impossible to testing of electric motors output quantity, therefore easily there is mistake, error is big, typically no longer uses at present
.
The method of motor applied load is a lot, such as adds flywheel, servomotor, brake etc..It is most commonly used at present to be
Brake, brake load are divided into three kinds of magnetic hysteresis, vortex and magnetic powder brake device.Magnetic hysteresis is most widely used, and vortex is used for rotating speed
Higher test, magnetic are used for big torque slow-speed of revolution test.
For the high-revolving motor of small torque, above method is difficult to accomplish accurately to measure, and above-mentioned load can not be real
The continuously adjustabe of existing rotary inertia.
The content of the invention
The utility model provides a kind of motor detection apparatus, for small torque pot motor rotating speed, torque, power, effect
The detection of rate, by using tunable load, the accurate detection of motor can be achieved.
The utility model takes the technical scheme to be：D.C. regulated power supply, tested motor, high-precision sensor, respectively with bottom
Seat is fixedly connected, and is wherein connected between tested motor and high-precision sensor by shaft joint one, D.C. regulated power supply is tested
Motor is powered, and tunable load is fixed on base, and the tunable load is connected by shaft joint two with high-precision sensor, is tested electricity
It is co-axially mounted between machine, high-precision sensor and tunable load three's rotary shaft；
Tunable load described in the utility model is loaded using electromagnetic damping formula.
The utility model advantage is structure novelty, and tunable load is loaded using electromagnetic damping formula, and resistance is produced using electromagnet
Power, the size of resistance is adjusted by slide-wire rheostat, realizes continuously adjustabe, and it is simple in construction, reliable, and detection efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
D.C. regulated power supply 1, tested motor 3, high-precision sensor 5, it is fixedly connected respectively with base 2, wherein tested electricity
Connected between machine 3 and high-precision sensor 5 by shaft joint 1, D.C. regulated power supply 1 is that tested motor 3 is powered, tunable load
6 are fixed on base 2, and the tunable load is connected by shaft joint 27 with high-precision sensor 5, and tested motor 3, high accuracy pass
It is co-axially mounted between sensor 5 and the three's rotary shaft of tunable load 6；
Tunable load 6 described in the utility model is using the load of electromagnetic damping formula.
Operation principle：D.C. regulated power supply 1 is adjustable from output voltage, and the voltage for adapting to different tested motors will
Ask；Tunable load 6 provides the rotary inertia of adjustable load；High-precision sensor 5 passes through the rotating speed measured and dtc signal
Signal wire is sent to host computer in real time；
During detection, D.C. regulated power supply progressively adjusts tunable load, made adjustable to the voltage required for tested motor input
Ascending change is loaded, until tested motor stall, i.e. the torque of now tested motor output reaches maximum；Whole process
In, the rotating speed of tested motor output, torque are all recorded and upload to host computer and shown, located in real time by high-precision sensor
Reason, the rotating speed exported by tested motor, torque can calculate power, the efficiency of tested motor according to physical knowledge.
