DC motor Wikipedia
The DC motor was the mainstay of electric traction drives on both electric and dieselelectric locomotives, streetcars/trams and diesel electric drilling rigs for many years The introduction of DC motors and an electrical grid system to run machinery starting in the 1870s started a new second Industrial RevolutionIt also provide unidirectional torque for dc motor; Material used It is made of a large number of edge shaped segments of hard drawn copper The Segments are insulated from each other by thin layer of mica OR The Segment of commutator is made of copper and insulating material between segments is mica 8 BrushesConstruction of DC Machine Polytechnic Hub

Motor control Wikipedia
Motor control is the regulation of movement in organisms that possess a nervous system Motor control includes reflexes as well as directed movement To control movement, the nervous system must integrate multimodal sensory information (both from the external world as well as proprioception) and elicit the necessary signals to recruit muscles to carry out a goalFig – 1 Difference Between AC & DC AC is more serial killer as AC with less frequency (50 Hz in EU and 60 Hz in US) is more dangerous than the DC having the same level of voltageIn other words, 230V AC (or 120V AC) is more dangerous than 230V DC or 120V DC respectivelyAC or DC Which One is More Dangerous And Why
