Dc motor characteristic curve
WebFrom comparison between this graph and the above characteristics of DC motors, you will find the following characteristic of induction motors. Changes in the load do not affect their speed much though their torque … WebDC MOTORS Basic DC motors as used on nearly all packaged drives have a very simple performance characteristic the shaft turns at a speed almost directly proportional to the voltage applied to the armature. Figure 1 shows a typical voltage/speed curve for a motor operating from a 115 volt control.
