Document Summary
In this lab we examine key characteristics of dc motors. In engineering applications incorporating dc motors, it is important to know the torque-speed relationship so that the right motor can be selected to match the performance requirements. Through this lab, we aim to further our understanding of these motors by learning new applications of this versatile piece of equipment. We have outlined our data and findings in this report. The scr is connected to the armature while the power is supplied to the field by a connector box dc motor. We viewed how the motor is working and obtained data. 4. 1 & 4. 2 using tachometer to measure rpm. We used a tachometer to measure the revolutions per minute (rpm) for the dc motor. It led to the results of around 1. 8 on the saf silicon controlled rectifier, which resulted in an rpm measured at. The measured rpm at 1. 5 speed was 15. 38.
