Description
Technical field
The utility model relates to a kind of DC motor speed test macro.
Background technology
Rotating speed is the very important parameter of motor, all will measure the rotating speed of motor in the systems such as a lot of motion, detection, explorations.At present, market there are centrifugal velocimetry, test generator velocimetry, photoelectric coding velocimetry, Hall element velocimetry, flash of light velocimetry etc. to concentrate the method for main measured motor rotating speed.Tachometer gage or tachometer and the object that tests the speed of centrifugal velocimetry or tech-generator method are rigidly connected, and add load to measurand, add the power consumption of motor, motionless tachometer gage is even with by some micromotor, is therefore not suitable for testing the speed of low-power machine; Photoelectric coding velocimetry and Hall element velocimetry are also on the axle of measurand, install porose disc or the disk with little magnet steel, although the load not having first two method to cause motor is large, but still there is impact for low-power machine, and these speed-measuring methods all will at some devices of the peripheral directly interpolation of measurand, test macro is made to seem crowded, both unsightly, measurement was also not accurate enough; And the flash of light rule that tests the speed will utilize the power source special of adjustable pulse frequency to be applied on flashlamp, the design of such light source is comparatively complicated, and test adjustment operation is complicated.
Summary of the invention
In order to solve the above-mentioned deficiency of existing motor speed method of testing, the utility model provides a kind of can not cause load, outward appearance brief introduction, simple to operate, the accuracy of detection that can improve motor, a kind of DC motor speed test macro of being particularly suitable for low-power machine to motor.
For this reason, the technical solution adopted in the present invention is: a kind of DC motor speed test macro, and primarily of power pack, control section and part of detecting composition, power pack power supply source is direct current adjustable stabilized voltage supply, to system power supply, the current value of testing of electric motors needs simultaneously; Control section comprises electron speed regulator and telepilot, is controlled the change of motor speed by telepilot; Part of detecting is rotational speed detector, tests motor speed under different electric current.
The power supply of described power pack is adjustable stabilized voltage supply, and system power supply simultaneously can the current value that needs of testing of electric motors.
Described control section is electron speed regulator and telepilot, and telepilot controls motor speed by controlling electron speed regulator.
Described part of detecting is rotational speed detector, tests the rotating speed of motor under different electric current.
The beneficial effects of the utility model are: providing one can change motor power consumption by changing telepilot throttle stroke, keeping voltage constant, measure motor speed under corresponding current fast.The utility model hardware cost is low, structure is simple, easy to operate, energy-conserving and environment-protective, security is high, working stability is reliable.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structured flowchart of the utility model embodiment.Each module title is as follows: direct current generator 1, electron speed regulator 2, wireless receiver 3, telepilot 4, adjustable stabilized voltage supply 5, rotational speed detector 6;
Fig. 2 is the utility model embodiment method of testing process flow diagram.
Embodiment
For further setting forth the present invention for the technological means reaching predetermined object and take and effect, below in conjunction with enforcement profit and accompanying drawing, the utility model is described in further detail, is described in detail as rear to the utility model.
With reference to Fig. 1: a kind of DC motor speed test macro, comprise power pack, control section and part of detecting composition, power pack power supply source is direct current adjustable stabilized voltage supply 5, to system power supply, and the current value of testing of electric motors needs simultaneously; Control section comprises electron speed regulator 2 and telepilot 4, is controlled the change of motor speed by telepilot; Part of detecting is rotational speed detector 6, tests motor speed under different electric current.
In the present embodiment, described electron speed regulator 2 is that 20A electricity is adjusted, and is convenient to telepilot and controls motor speed measurement.Described rotational speed detector 6 is stroboscope.
With reference to Fig. 2, a kind of DC motor speed method of testing, comprises the following steps:
1) system initialization;
2) motor power consumption is changed by changing telepilot throttle stroke;
3) keep voltage constant, and read current value;
4) testing of electric motors rotating speed, motor speed under use rotational speed detector test corresponding current.
The principle of work of the present embodiment: under the condition of adjustable stabilized voltage supply voltage constant, when direct current generator 1 works, change by changing telepilot throttle stroke the current value that direct supply exports, current value stablizes the rotating speed of motor under rear use rotational speed detector test corresponding current value.
