Wireless Rotor Runout Kit
(iPad, rotor, dimensional measurement, angle measurement, Bluetooth)

Motionics Wireless Rotor Runout Kit is a novel tool for rotor runout measurement. It consists of a Bluetooth dial indicator BlueDial, a Bluetooth angle sensor BlueAngle and the iPad application Runout. Together these sensors work to seamlessly measure both circumference deflection and rotor rotating angles to show the real shape of the rotor on an iPad.

You can visit the individual pages of each sensor to find out specifications and more hardware information.

How it Works

Users can attach BlueAngle to the end face or the circumference of a rotor with its magnetic base. While the rotor rotates, BlueAngle also rotates with it and continuously measures the rotating angle. At the same time, BlueDial can be set to measure at the edge of the rotating plane. Both sensors transmit data wirelessly to iPad. In the Runout app, displacement measurements from BlueDial and rotating angle readings from BlueAngle are matched to depict the real contour of the rotor in test.

To better visualize collected data, we embed a probe meter for BlueDial readings. Two different options of probe meters with different numbers of ticks are available for different resolution requirements. Additional, users can freely set the range of the probe meter to further adjust display resolution. An analog needle rotates while BlueDial reading changes. For BlueAngle, a rotating arrow follows the value of BlueAngle, indicating the angular position of the rotor.

Runout App can connect up to 4 displacement sensors simultaneously, allowing users to conduct runout test for 4 planes at the same time. An individual reading panel is assigned to each sensor connected without interference between each other.

When starting a Runout test session, user can define the number of test points needed for one revolution of the rotor. With our wireless runout kit, instead of marking all testing points, stopping at each of them and writing down values, the Runout app itself automatically triggers data recording once BlueAngle reaches the preset angular position. The corresponding dash line on rotating angle indicator will also change to solid green line, indicating value for this angle has been recorded. In the end of each test, values and locations of maximum/minimum readings are summarized in the result table. By tapping at the summary, readings for each test point are shown in the reading table. A plot page is also available to view both cartesian plot and polar plot.

A new smoothing feature is added to the App in case the roughness of rotor surface introduces undesired spikes to the measurement. By adjusting the averaging parameter slider, users can select to use different numbers of samples for averaging and see the smoothing effect right away on the plot. Once the optimum parameter is found, the smoothed result can be saved as a new entry to the test result table.

Once the test session is complete, user can export test data or create and save a test report on the iPad. A local test record manager will allow future access to previous tests data and reports.
