The final installment in our Baldor Motor Basics series covers 50 Hz requirements, as well as motors wet or damp environments.

Explosion-Proof Motors in Division 2 Areas and DC Drive Fundamentals

Failure to specify the proper motor for use in a hazardous location can have serious consequences - lost production, extensive property damage, and even loss of human life. Selection of the proper motor requires an understanding of Underwriters Laboratories' (UL) and National Electrical Code (NEC) class, group and division designations and the T code letters.

Amps, Watts, Power Factor and Efficiency; Approximate Load Data from Amperage Readings; Power Factor Correction on Single-Induction Motors.

Conservation through lighting alterations using different bulbs, ballasts and light sources is well understood and easy to achieve. The use of improved efficiency three phase induction motors has not been as accepted. There are a number of reasons why conservation efforts with motors have not been as popular.

Understanding proper bearing lubrication procedures is critical to ensuring long-term, trouble-free performance. Klüber Lubrication has prepared this explanation as a general guide.

Part 1: There seems to be a lot of confusion about the voltage standards for motors and why they are structured the way they are. Part 2: The effect of low voltage on electric motors is pretty widely known and understood, but the effect of high voltage on motors is frequently misunderstood.
