Motor starter with speed control

Nettet12. okt. 2024 · The different mechanisms of speed control can be deduced from the speed equation of a DC motor. From the above expression, it can be revealed that the speed can be controlled by any one of the following three factors. by varying the field current and hence flux per pole φ. by varying the armature resistance, Ra and so the … NettetStarters are made from two building blocks, contactors and overload protection: • Contactors control the electric current to the motor. Their function is to repeatedly establish and interrupt an electrical power circuit. • Overload Protection protects motors from drawing too much current and overheating, from literally “burning out.” = +
