Electric Motors and My Job
I work at Baldor Electric Company as an Electrical Design Engineer. My primary duty is applying electrical specifications to fit customer orders. If there are no existing designs which will work, I will design a motor that will. I work primarily with motors 250 thru 440 NEMA frames. This generally goes from 7.5 thru 400 Hp, depending on the speed and enclosure of the motor.
I use a program developed in house by Baldor to calculate the performance of a design. This program uses Fortran for the calculations with a Pascal front end as a user interface. I also use spreadsheets to predict some of the characteristics of a motor. Some of these characteristics include safe stall times, time to accelerate an inertia as well as some common calculations involving horsepower, speed and torque.
