Abstract
The utility model relates to a short circuit testing device for a motor driver, comprising a bulb, an electric wire and a power supply, wherein an output motor plug of the motor driver is connected with the bulb through the electric wire; the power supply is used for supplying power to the motor driver and the bulb; and the maximum current permitted by the bulb is larger than the short circuit current of the motor driver. In the short circuit testing device for a motor driver, a short circuit testing result can be more easily judged by adopting the high-power bulb, connecting the bulb with the output motor plug of the motor driver and observing whether the brightness of the bulb reaches the highest or not so as to judge the short circuit protection property of the tested motor driver. The detection device is safe and reliable during working, has low cost and can greatly improve the quality of the motor driver products.
Description
Technical field
The utility model relates to the motor driver field, specifically, is a kind of short-circuit test device that is used for motor driver.
Background technology
The Electric Machine Control driver is used for controlling the startup of motor and stopping, and the Electric Machine Control driver generally all has the function of short-circuit protection, and when the motor short circuit, driver can in time turn-off output current, and the element of protection motor internal is not burnt.
Though motor driver has the function of short-circuit protection when design, in the process of manufacturing, each product all may exist quality bad, if crucial performance not test aborning such as short-circuit protection, this can bring potential safety hazard to the user.Because big short circuit current can produce heating and damage element, does not therefore have a kind of fixing inspection process in the former production.
Existing solution is: in one batch, only spot-check several drivers and do various tests, comprise short-circuit test, see if there is the bad driver of short-circuit protection performance with inspection.This detection scheme is quite loaded down with trivial details, and owing to just spot-check the part machine, so can't guarantee the reliable and secure of All Drives product short-circuit protection performance in this production batch.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of short-circuit test device that is used for motor driver is proposed; can detect the quality of driver short-circuit protection performance easily; can do short-circuit test to the All Drives in producing; improved the quality of product greatly; it is loaded down with trivial details thoroughly to have solved the technical operation of existing driver short-circuit detecting, the shortcoming that detection efficiency is low.
The utility model is achieved through the following technical solutions:
Be used for the short-circuit test device of motor driver, comprise bulb, electric wire, power supply, the output motor plug of motor driver connects bulb by electric wire, and power supply is given motor driver, bulb powered.
The maximum current that described bulb can pass through is greater than the short-circuit current of motor driver.
Beneficial effect: the utility model is used for the short-circuit test device of motor driver; by adopting a powerful bulb; and bulb is connected with the output motor plug of motor driver; whether reach the brightest by the brightness of observing bulb; just can judge the result of short-circuit test with comparalive ease; judge the quality of the short-circuit protection performance of tested motor driver; pick-up unit of the present utility model is safe and reliable when work; with low cost, can improve the motor driver product quality greatly.
Description of drawings
Fig. 1 is the structural representation of motor driver when drive motor in the utility model;
Fig. 2 is the structural representation of short-circuit test device when carrying out short-circuit test in the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Embodiment:
Referring to Fig. 1, comprise power supply 1, motor driver 2, motor 3 among the figure, the output motor plug of motor driver 2 connects motor 2 by electric wire, and power supply 1 is given motor driver 2, motor 3 power supplies.
Referring to Fig. 2, comprise power supply 1, motor driver 2, bulb 4 among the figure, the output motor plug of motor driver 2 connects bulb 4 by electric wire, and power supply 1 is given motor driver 2, bulb 4 power supplies.The maximum current that bulb 4 in the present embodiment can pass through is greater than the motor driver short-circuit current.
The utility model is when the testing of electric motors driver:
1, at first, the output motor plug with motor driver 2 is connected by electrical wiring to a high-power bulb 4;
2, guarantee maximum current that bulb 4 can pass through short-circuit current greater than motor driver 2, such as short-circuit current protection point is designed to 10A, select the enough little bulb of a resistance 4, make its electric current that can pass through can reach 15A, bulb 4 is the brightest when passing through the electric current of 15A;
3, the starter motor driver 2, observe the brightness of bulb 4, if bulb 4 does not reach the brightest, the electric current that passes through this moment are described at 10A, and the short-circuit protection function of motor driver 2 has played effect; If bulb 4 has reached the brightest, illustrate that the electric current that passes through this moment is 15A＞10A, illustrate that the short-circuit protection of motor driver 2 does not work, product is defective.
Show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. be used for the short-circuit test device of motor driver, it is characterized in that, comprise bulb, electric wire, power supply, the output motor plug of motor driver connects bulb by electric wire, and power supply is given motor driver, bulb powered.
2. the short-circuit test device that is used for motor driver according to claim 1 is characterized in that the maximum current that described bulb can pass through is greater than the short-circuit current of motor driver.
