How does a simple DC motor work GCSE?
How does a simple DC motor work GCSE?
A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. The electromagnet is now repelled by the south pole of the permanent magnet, and moves away from it.
How does a simple DC motor work?
A simple DC motor uses a stationary set of magnets in the stator, and a coil of wire with a current running through it to generate an electromagnetic field aligned with the centre of the coil. The commutator allows each armature coil to be energised in turn, creating a steady rotating force (known as torque).
How does a DC motor work class 10?
D.C. motor can be defined as a machine which converts electrical energy to mechanical energy of rotation based on the principle of magnetic effect of current. The DC motor works according to Fleming’s right hand rule. When the armature is rotated in the clockwise direction, the split rings are connected to the brushes.

What is the full form of DC motor?
A direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through direct current, and convert this energy into mechanical rotation.
What is the example of DC motor?
1 Introduction. Direct-current motors are extensively used in variable-speed drives and position-control systems where good dynamic response and steady-state performance are required. Examples are in robotic drives, printers, machine tools, process rolling mills, paper and textile industries, and many others.
How does a DC motor turn electricity into motion?
Electric motors turn electricity into motion by exploiting electromagnetic induction. A simple direct current (DC) motor is illustrated below. The motor features a permanent horseshoe magnet (called the stator because it’s fixed in place) and an turning coil of wire called an armature (or rotor, because it rotates).
What causes a d.c.motor to rotate?
Electricity & Magnetism 4.6 Electromagnetic Effects 4.6.9 D.C. Motor When there is a current in the coil, the magnets exert a turning effect on the coil, causing it to rotate
How are the different types of DC motors different?
A Direct Current (DC) motor is a motor that turns energy from a direct current and turns this into mechanical energy. There are four types of DC motors
How does the torque of a DC motor work?
Consider the load on a dc motor is suddenly reduced. In this case, required torque will be small as compared to the current torque. Speed of the motor will start increasing due to the excess torque. Hence, being proportional to the speed, magnitude of the back emf will also increase. With increasing back emf armature current will start decreasing.
