A DC motor is an electrical machine that converts electrical energy into mechanical energy. The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force.
We know that a DC motor has an armature which rotates within a magnetic field, and the main working principle of this motor depends on a current carrying conductor which is arranged in a magnetic field, and the mechanical force will be experienced with the conductor.
A DC Motor like we all know is a device that deals in the conversion of Electrical energy to mechanical energy and this is essentially brought about by two major parts required for the construction of dc motor
DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings.
What is a Brushless DC or BLDC Motor? A Brushless DC Motor, BLDC accomplishes commutation electronically using rotor position feedback to determine when to switch the current. The BLDC motor is electrically commutated by power switches instead of brushes. The structure of Brushless DC Motor, BLDC is shown in figure below. In simple words, a 
11-2-2013· Construction. BLDC motors have many similarities to AC induction motors and brushed DC motors in terms of construction and working principles respectively. Like all other motors, BLDC motors also have a rotor and a stator. Stator. Similar to an Induction AC motor, the BLDC motor stator is made out of laminated steel stacked up to carry the
Synchronous Motor Working Principle and Construction. Principle and Operation of Synchronous Motor. When an induction motor is connected to a three-phase supply, a rotating magnetic field is established; this induces currents in the rotor windings, thereby producing a torque.
Construction of brushless Dc motor: We can say that brushless motor has the same construction of Ac induction motor and brushed Dc motor; like all other motors, there is a stator and a rotor. The stator: The stator of this motor made of laminated steel stacked up to carry the windings which may be arranged in star (Y) or delta (∆) pattern.
DC servo motor : The basic operating principle of DC motor is the same as other electromagnetic motors. The design, construction, and the modes of operation are different. The rotors of this kind of motor are designed with long rotor length and smaller diameters. Their size is larger than that of conventional motors of same power ratings. DC
DC Motors Although ac motors are used in most of the cases, DC motors have many applications and used for multi-purpose applications. DC Motor Principle A machine that converts dc power into mechanical energy is known as dc motor. Its operation is based on the principle that when a current carrying conductor is placed in a
THEORY, CONSTRUCTION, AND OPERATION 1. CHAPTER 1 PRINCIPLES OF OPERATION Other members of the family are the direct-current (dc) motor or generator, the induction motor or generator, and a number of derivatives of all these three. What is common to all the members of this fam- (dc) electric power. The dc can be considered a particular
DC Shunt Motor Construction and Working Principle. The DC shunt motor construction is the same as any type of DC motor.This motor can be constructed with the basic parts like field windings (stator), a commutator and an armature (rotor)..
Stepper motor is a specially designed DC motor that can be driven by giving excitation pulses to the phase windings. They cannot be driven by just connecting the positive and negative leads of the power supply. They are driven by a stepping sequence which is generated by a controller. The...
A commutated DC motor has a set of rotating windings wound on an armature mounted on a rotating shaft. The shaft also carries the commutator, a long-lasting rotary electrical switch that periodically reverses the flow of current in the rotor windings as the shaft rotates. Thus, every brushed DC motor has AC flowing through its rotating windings.
