Electric Motor Search Search motors across all brands on one platform Just type in the motor part# or the motor specifications you are looking for and a list of motors matching your query will come up Alternatively you can use drop down search to configure the exact motor you are looking for View Demo Across-the-line powered motors The most common underlying cause of unwanted bearing currents in sine wave-driven motors is alternating flux which is a result of asymmetric magnetic properties of the stator or rotor core Fig 1 In this sine wave powered motor bearing currents result from time-varying flux encircling the motor shaft

The purpose of insulated bearing for Motors with VFD drives or the Alternators is to prevent the flow of circulating current in a closed circuit through bearing and ground (if bearing is not insulated) and consequently prevent the bearing from damage This circulating current is caused by induced voltage in the shaft because of AC flux

2012-5-20The motor standards can be grouped into two major categories: NEMA and IEC (and its derivatives) In North America the National Electric Manufacturers Association (NEMA) sets motor standards including what should go on the nameplate (NEMA Standard MG 1-10 40 Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors)
