VFD training is one of our more requested services, and we’ve recently started offering specific, hands on training on the Siemens Robicon Perfect Harmony medium
Fuelfix estimates that trillions of dollars more in oilfield projects are subject to cancellation due to low crude prices. Companies are looking for ways to
We’re now offering hands-on training on Medium Voltage Variable Frequency Drives (MV VFDs)
Organic Technology: Advances in electrical physics are most often associated with European, and recently, Asian cultures. As in the fields of medicine and astronomy however,
It’s well documented that VFD bus capacitors have a limited life span and at some point require replacement….preferably prior to a catastrophic failure.
GE Multilins have become the motor protection du jour in many facilities running large medium voltage motors. We began programming the Multilins some time ago
The 20 year typical cost of ownership on a large AC motor is shown on the chart below. We can realize significant savings on variable
EMA repairs and services medium voltage soft starters. We also routinely perform preventive maintenance on the medium voltage soft starters.
A young man from Korea recently taught a training class at our Georgia facility. At dinner that evening we asked him about the Thanksgiving holiday,
EMA recently installed a Siemens Robicon Perfect Harmony Medium Voltage VFD test stand.
Active front end VFDs. A little overview.. The most common VFD technology uses diode rectifiers to convert the incoming line AC to DC, which is
You don’t build a business.. you build people and they build a business Zig Ziglar We have the best people I know working at EMA.
We are often called upon to change bus capacitors in large VFDs. As a result, we have a number of bus capacitors to sell. Bus
Medium Voltage (MV) motors require special consideration compared to low voltage AC motors. For one thing, medium voltage AC motors are usually high horsepower power
