GCSE Physics: Motor Effect - commutator

WebA DC motor or direct current motor is an electrical machine that transforms electrical energy into mechanical energy by creating a magnetic field that is powered by direct current. When a DC motor is powered, a magnetic field is created in its stator. The field attracts and repels magnets on the rotor; this causes the rotor to rotate. WebHow they work Motors have many different working parts in order for them to continually rotate, providing power as needed. Motors can run off of direct current (DC) or alternating current (AC), and both have their benefits and drawbacks. For the purpose of this article a DC motor will be analyzed, to read about AC motors, click here. grantham college open evening

WebThe basic mechanism of a DC motor. All inductive loads (like motors, electromagnets, and solenoids) work on this same principle: induce a magnetic field by putting current through … WebThe Commutator. The answer is to use a commutator. This device prevents the wires from twisting. More importantly it actually allows the coil to keep rotating in one direction! The one shown is a split-ring commutator. It has two halves, each connected to the power supply, completing the coil circuit. The coil is able to turn smoothly around it. WebApr 21, 2024 · Electricity is the flow of electrons through a wire. When lots of electrons flow in the same direction we call this current. DC electricity means the electrons flow in just a single direction, from one terminal of a battery directly to the other. If we reverse the battery then the current will flow in the opposite direction. Electricity Basics chipboard brackets
