Calculation of transient torsional stresses ... The transient torques of a synchronous motor were measured during startup (Figure 1827) by attaching a strain gauge to the motor shaft and obtaining the signal with an FM telemetry system. A synchronous motor produces a pulsating torque [39] that varies from twice line frequency as it starts to zero frequency when it is synchronized with the ...

A treadmill that stops running after starting the workout can mean something is wrong with the belt, platform, motor or speed controls. When too much resistance occurs during a run or walk, the treadmill stops running to avoid any damage to the motor. This is a safety precaution to preserve the motor and to avoid excess heat which can cause fires in the home. A treadmill owner can check a few ...

 · Finally, one of the best ways to minimize the pressure and power stresses during startup and shutdown is to install a VFD, which has many additional benefits [see WW, March 2008]. Variable frequency/speed drives eliminate the inrush current and pressure spikes on startup. Softstarting reduces the stress on the motor, pump, coupling and the supply network.

Jun 01, 2012 · Oscillations in stress, such as those created by earthquakes, can increase permeability and fluid mobility in geologic media. In natural systems, strain amplitudes as small as 10−6 can increase discharge in streams and springs, change the water level in wells, and enhance production from petroleum reservoirs. Enhanced permeability typically recovers to prestimulated values over a period .
