Megohmmeters (meggers) are electrical meters used to check the resistance and condition of the motor windings and the condition of the refrigeration and oil environment around the motor windings. A ...

The operation of an electric motor is typically simple and reliable, making it possible to overlook during day-to-day maintenance practices. Having a checklist makes it easy to know exactly what to ...

HVAC distributor cfm Distributors recently developed a list of items to test and/or questions to ask when dealing with sites that have experienced multiple failed compressors. The first step consists ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

Appliance makers are always looking for quieter, moreefficient motors. Although they've been using singlephase, single-winding, twopole synchronous motors for decades, such motors can be inefficient ...

Electric dc brush motors have traditionally used wire-wound armatures that move through a magnetic-flux air gap. Engineers at ThinGap Motor Technologies, Santa Barbara (www.thingap.com), have come up ...
