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 ...
For retrofits Electro Static Technology’s AEGIS® Shaft Voltage Test Kit makes it easier than ever to measure and document damaging VFD-induced voltages while there is still time to head off bearing ...
This article was updated Feb. 20, 2023. It was originally published March 2, 2011. Engineers are constantly called on to select motors for the applications that will be able to do the task at hand and ...
With the increasing use of variable-frequency drives (VFDs), there is increased generation of electrical currents on shaft motors, causing electrical damage to bearings. Manufacturers and end users ...
In the age of energy efficiency, engineers are often excited about the potential cost savings associated with variable-frequency drives (VFDs) and their ability to operate motors to match demand loads ...
