iRotorBalance SP1 is an educational and technical tool for balancing of rotating machinery in single plane using the four-runs method. The iPad application connects to the hardware to collect the vibration data with the accelerometer and calculates the correction balancing weight and its angular position.

iRotorBal SP1 requires external hardware for proper operation. A complete hardware package, including an iPad, data acquisition and an external accelerometer (by GTI Spindle Technology) is available. Please contact Motionics LLC for the details (
