Question
Chapter 20, Problem 1RQ
To determine
The indication shown by TENV on the nameplate of the motor.
Expert Solution & Answer
Explanation of Solution
The National Electrical Manufacturers Association defines some basic parameters regarding the design and dimensions in order to define the basic performance and mounting parameters.
These parameters are coded on the motor nameplate in order to define the key features of the motor. The information which is inscribed on the motor nameplate is arranged by categories.
TEMV stands for totally enclosed non ventilated type motor which indicates that the motor is sealed in such a way that it is totally safe from dirt and humidity although hot environment is not favorable for these kind of motors.
