Abstract

A testing device configured to operate as a dedicated tool for testing motor drives and motor shafts guides a user (such as a test engineer or a technician) through the steps of testing the motor drive and shaft. The testing device is configured to output testing results to the user. By configuring the testing device to output specific motor drive and shaft measurement results and by guiding a user through the steps of performing the measurement, operation of the testing device is simplified.

First claim

The invention claimed is:

1. A scopemeter, comprising:
one or more probes;
an input device;
a display;
a processor; and
memory configured to store executable instructions that, when executed by the processor, cause the processor to:
cause a motor drive stage selection menu to be displayed on the display, the motor drive stage selection menu listing a plurality of motor drive stages;
receive, via the input device, a selection of a motor drive stage of the plurality of motor drive stages;
in response to receiving the selection of the motor drive stage, cause a test selection menu to be displayed on the display, the test selection menu listing a plurality of tests associated with the motor drive stage of the plurality of motor drive stages;
receive, via the input device, a selection of a test of the plurality of tests;
in response to receiving the selection of the test of the plurality of tests, display an operational menu associated with the test, the operational menu including a representation of a connectivity of the one or more probes to the motor drive stage for the test, and the representation including a diagram showing connections to be made by one or more voltage probes or one or more current clamps;
cause the test to be performed on the motor drive stage; and
display a result of the test that is performed on the motor drive stage.

2. The scopemeter of claim 1 , wherein the plurality of motor drive stages include at least one of a drive input stage, a drive stage or a motor and drive train stage.

3. The scopemeter of claim 2 , wherein the executable instructions cause the processor to:
in response to receiving a selection of the drive input stage:
cause the test selection menu to be displayed including a listing of one or more of: a voltage test, a current test, a frequency test, a voltage unbalance test or a current unbalance test of the drive input stage; and
receive a selection of at least one of: the voltage test, the current test, the frequency test, the voltage unbalance test or the current unbalance test of the drive input stage.

4. The scopemeter of claim 1 , wherein the plurality of motor drive stages include at least one of: a drive input stage, a drive direct current (DC) bus stage, a drive output stage, a motor input stage or a motor shaft state.

5. The scopemeter of claim 4 , wherein the executable instructions cause the processor to:
in response to receiving a selection of the drive DC bus stage:
cause the test selection menu to be displayed including a listing of one or more of: a voltage test, a ripple test or a voltage unbalance test of the drive DC bus stage;
receive a selection of at least one of: the voltage test, the ripple test or the voltage unbalance test of the drive DC bus stage; and
in response to receiving the selection of the at least one of: the voltage test, the ripple test or the voltage unbalance test of the drive DC bus stage, cause the at least one of: the voltage test, the ripple test or the voltage unbalance test of the drive DC bus stage to be performed on the drive DC bus stage.

6. The scopemeter of claim 1 , wherein:
the motor drive stage selection menu includes an information tab, and
the executable instructions cause the processor to:
receive user selection of the information tab; and
in response to receiving the user selection of the information tab, display information associated with items displayed in the motor drive stage selection menu.

7. The scopemeter of claim 1 , wherein the executable instructions cause the processor to save a report including the result of the test that is performed on the motor drive stage in the memory or transfer the report to a separate device.

8. A method, comprising:
causing a motor drive stage selection menu to be displayed on a display, the motor drive stage selection menu listing a plurality of motor drive stages;
receiving, via an input device, a selection of a motor drive stage of the plurality of motor drive stages;
in response to receiving the selection of the motor drive stage, causing a test selection menu to be displayed on the display, the test selection menu listing a plurality of tests associated with the motor drive stage of the plurality of motor drive stages;
receiving, via the input device, a selection of a test of the plurality of tests;
in response to receiving the selection of the test of the plurality of tests, displaying an operational menu associated with the test, the operational menu including a representation of a connectivity of the one or more probes to the motor drive stage for the test, and the representation including a diagram showing connections to be made by one or more voltage probes or one or more current clamps;
causing the test to be performed on the motor drive stage; and
displaying a result of the test that is performed on the motor drive stage.

9. The method of claim 8 , wherein the plurality of motor drive stages include at least one of a drive input stage, a drive stage or a motor and drive train stage.

10. The method of claim 9 , comprising:
in response to receiving a selection of the drive input stage:
causing the test selection menu to be displayed including a listing of one or more of: a voltage test, a current test, a frequency test, a voltage unbalance test or a current unbalance test of the drive input stage;
receiving a selection of at least one of: the voltage test, the current test, the frequency test, the voltage unbalance test or the current unbalance test of the drive input stage; and
in response to receiving the selection of the at least one of: the voltage test, the current test, the frequency test, the voltage unbalance test or the current unbalance test of the drive input stage, causing the at least one of: the voltage test, the current test, the frequency test, the voltage unbalance test or the current unbalance test of the drive input stage to be performed on the drive input stage.

11. The method of claim 8 , wherein the plurality of motor drive stages include at least one of: a drive input stage, a drive direct current (DC) bus stage, a drive output stage, a motor input stage or a motor shaft state.

12. The method of claim 11 , comprising:
in response to receiving a selection of the drive DC bus stage:
causing the test selection menu to be displayed including a listing of one or more of: a voltage test, a ripple test or a voltage unbalance test of the drive DC bus stage;
receiving a selection of at least one of: the voltage test, the ripple test or the voltage unbalance test of the drive DC bus stage; and
in response to receiving the selection of the at least one of: the voltage test, the ripple test or the voltage unbalance test of the drive DC bus stage, causing the at least one of: the voltage test, the ripple test or the voltage unbalance test of the drive DC bus stage to be performed on the drive DC bus stage.

13. The method of claim 8 , wherein:
the motor drive stage selection menu includes an information tab, and
the method includes:
receiving user selection of the information tab; and
in response to receiving the user selection of the information tab, displaying information associated with items displayed in the motor drive stage selection menu.

14. The method of claim 8 , comprising:
saving a report including the result of the test that is performed on the motor drive stage or transferring the report to a separate device.

15. A scopemeter, comprising:
one or more probes;
an input device;
