Motor Vibration Analysis: Keeping It Simple

Vibration Analysis - An Animated Introduction by Mobius Institute It isolates the motor/base system from the measurement. The first measurements you take should represent the machine under normal operation and may indicate the tests you should perform next. This condition removes all effects of the coupling and mechanical load driven by the motor.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.

When Does Poor Power Quality Cause Electronics Failures? Code Q&a: Protection Of Type Mc Cable Cable connectors with insulated throats that are suitable for use with either Type AC or Type MC cable are a satisfactory substitute for the insulating bushings. If this type of fitting is used, the cable should be fully inserted into the connector so that the cut end of
Energy Department Seeks Information On Efficient And Flexible Building Loads Efficient and flexible building loads provide options to increase electricity system reliability and energy affordability, while also supporting a portfolio of generation options in grid modernization. To date, savings resulting from flexible building loads have been primarily achieved through traditional… Choosing Transformers For power distribution projects demand For Horticultural Lighting Is Driving Research And Development

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.

2011 National Electrical Code Changes Code Q&a: Protection Of Type Mc Cable Cable connectors with insulated throats that are suitable for use with either Type AC or Type MC cable are a satisfactory substitute for the insulating bushings. If this type of fitting is used, the cable should be fully inserted into the connector so that the cut end of
