DC Motor Basics, Construction, Types & Its Application
What is DC Motor? Construction of DC Motor. The construction of the DC motor is shown below. It is very important to know its design DC Other types of DC motors require no commutation. • Homopolar motor A homopolar motor has a magnetic field along the axis of rotation and an electric current that at some point is not parallel to the magnetic field. The name homopolar refers to the absence of polarity change. Homopolar motors necessarily have a single-turn coil, which limits them to very low voltages. This has restricted the practical application of this type of motor.DC motor

Electric motor
The coreless or ironless DC motor is a specialized permanent magnet DC motor. Optimized for rapid acceleration,the rotor is constructed without an iron core. The rotor can take the form of a winding-filled cylinder, or a self Position the armature in the paper clip loops, with the shiny, uncolored side touching the paper clips. Make sure it doesn’t touch the magnet. If your motor doesn’t start immediately, try giving it a start by spinning the wire bundle. Since the motor will only spin in one direction, try spinning it both ways.How to Make a DC Motor Simple Science Project + Video from

DC Motor: Types, Working Principle, Applications Collegedunia
A direct current (DC) motor is a form of electric machine that converts electrical energy into mechanical energy. DC motors take electrical power through the direct current and convert this energy into mechanical rotation. The three main types of DC motor that are available are: Shunt, Series, and Compound. DC shunt motors can be used for The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. Any dc Construction of DC Machine (Generator & Motor)

Electric motor
Animation showing operation of a brushed DC electric motor. An electric motor is an electrical machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's The term ‘DC motor’ is used to refer to any rotary electrical machine that converts direct current electrical energy into mechanical energy. DC motors can vary in size and power from small motors in toys and appliances to large mechanisms that power vehicles, pull elevators and hoists, and drive steel rolling mills.Everything You Need To Know About DC Motors RS

Brushless DC Motors Part I: Construction and Operating Principles
Working Principles and Operation. The underlying principles for the working of a BLDC motor are the same as for a brushed DC motor; i.e., internal shaft position feedback. In case of a brushed DC motor, feedback is implemented using a mechanical commutator and brushes. With a in BLDC motor, it is achieved using Construction of BLDC Motor. The main design difference between a brushed and brushless motors is the replacement of mechanical commutator with an electric switch circuit. Keeping that in mind, a BLDC Motor is a type of synchronous motor in the sense that the magnetic field generated by the stator and the rotor revolve at the same Introduction to Brushless DC Motors (BLDC Motor) Electronics

Construction and Working Principle of DC Generators
A DC generator operates on the principle of electromagnetic induction i.e. when the magnetic flux linking a conductor changes, an EMF is induced in the conductor. A DC generator has a field winding and an armature winding. The EMF induced in the armature winding of a DC generator is alternating one and is converted into direct A DC machine is an electromechanical energy alteration device.

There is no basic difference in the construction of a DC generator and a DC motor.. In fact, the same DC machine can be used interchangeably as a generator or as a motor. Like generators, there are different types of DC motors which are also classified into shunt-wound, series-wound and compound-wound dc motors.. DC motors are The construction is same for DC motor and DC generator. Working of DC Machine The working principle and operation of a DC machine is based on an effect when a current carrying conductor coils laying in a magnetic field, the magnetic field produces a mechanical force on it known as torque which rotates the conductor coils in magnetic field.DC Machine Construction, Working, Types and Applications
