Abstract
This paper presents the results of tests to determine the speed-torque characteristics of a d-c series motor driving a crane hoist. Direct readings of speed and torque during dynamic braking lowering operation were taken for various values of resistance in the motor circuit branches. A comparison between test data and calculated performance, using a conventional method of calculation, indicates that calculation obtains performance curves which are sufficiently accurate to forecast the performance of a practical crane hoist controller.
