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.

In the process of applying industrial drive products, we occasionally are misled into believing that we are applying horsepower. The real driving force is not horsepower - it is torque. This paper is developed to impart a deeper understanding of torque, its relationship to horsepower, and the types of loads we most frequently encounter.

This issue our Baldor Basics series continues with the topics of motor temperature ratings and metric motors.
