The Electric Elevator H. D. James: We often hear engineers speak of the difference in efficiency between electric elevators of the same size, and many of them seem at a loss to understand why this difference exists. It will perhaps be made a little clearer to many of them if we analyze the various sources of loss which occur between the motor and the load, and point out some of the factors which cause a variation in these losses.
