The objective of optimized shaft alignment is to increase the operating life span of rotating machinery. To achieve this goal, components that are the most likely to fail must be made to operate ...

High vibration is a common problem for motors installed on top of vertical pumps. Its source can stem from a mechanical issue with the pump, motor, or coupling — or even hydraulic forces from the pump ...

Mechanical Dynamics and Analysis (MD&A) was retained by a utility to perform a stub-shaft repair of a generator rotor collector-end shaft. The customer reported that the generator rotor had suffered a ...

One of the more common repairs needed for many Corvettes is axleshaft u-joint replacement. In IRS cars, Corvette axleshaft u-joints constantly change drive angles as the suspension traverses bumps and ...

• The major issue with all parallel-drive systems is orthogonal alignment. • The dynamic motion generated by any two identical linear-shaft motors is the same ...

Small and medium AC induction motors account for more than 75% of motor electrical energy demand; however, they typically receive less maintenance than their larger counterparts. This leaves them ...

Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...
