Through proper application of simulation and modeling within industrial environments, greater impact for energy, waste and production improvements can occur. Modern simulation and modeling systems can help determine impacts of energy and waste reduction concepts on production and vice-versa. Through a 1999 Illinois Department of Commerce and Community Affairs funded project, improvements of over 40%…
A new inline ventilation motor operating on a VFD with bypass tripped on startup with the VFD and instantaneously tripped when tested across the line. Smoke was noted in the drive cabinet and MotorDoc was contacted to evaluate the electric motor and work with the VFD installer following recommendations by repair shops to remove the…
Initial testing of an ID fan performed in 2018 with corrections made and retesting performed with EMPATH analysis, GTI Predictive vibration analysis and RDI motion amplification. While values were not extreme in the pre-test, the resulting vibration destroyed fan bearings and other poor conditions which prevented the operation of the fan system. Testing was performed…
As we start into ESA theories and application, we will have to spend a little time on electric motor theory. As we will start out with a basic system, AC motors are the simplest in terms of operation and components, we will start out with AC induction motors. Using this base knowledge, we can later…
It does happen, although rarely, in typical industrial environments that an electric machine will die of old age. The reason is that machines are often exposed to contamination issues, other environmental issues, power issues or a combination of events that degrade the insulation slowly or rapidly. There is also a rule of reliability that should…
This is not my normal style of writing or presenting. These are thoughts on leadership within governments during the global pandemic. They reflect my personal views as they stand at this moment. Audio or paper – enjoy.
Based upon increasing concerns surrounding business during the Covid-19 outbreak, please find the MotorDoc LLC commitment to safety in relation to the pandemic. MotorDoc LLC is considered an essential business for field services, maintenance and testing. With the conditions rapidly changing, we outline how we are approaching different conditions.
Free Seminar April 20, 2020 from noon to 1pm CST We will discuss the art of EMPATH data collection and analysis of wind turbine generators, gearbox, main bearings and blades from the voltage and current. We will discuss how the data is collected and the approach to analysis. This will be exclusive for wind companies…
Free Live Seminar for April 17, 2020 from noon to 1pm CST In this presentation we will work step-by-step how to analyze an electric motor, sheaves, belts and fan including related bearings using real field data. The demonstration will be with the EMPATH system but applies to other current and electrical signature analysis. GoToWebinar to…
