  • THEORY, CONSTRUCTION, AND OPERATION

    THEORY, CONSTRUCTION, AND OPERATION 1. OF SYNCHRONOUS MACHINES The synchronous electrical generator (also called alternator) belongs to the family of electric rotating machines. Other members of the family are the direct- direct-current (dc) electric power. The dc can be considered a particular case ofClassifications of DC machines : (DC Motors and DC,Each DC machine can act as a generator or a motor. Hence, this classification is valid for both: DC generators and DC motors. DC machines are usually classified on the basis of their field excitation method. This makes two broad categories of dc machines; (i) Separately excited and (ii) Self-excited.

  • What is a DC Machine? Basic structure & Equivalent circuit

    DC Machine A DC Machine is an electro-mechanical energy conversion device.There are two types of DC machines; one is DC generator, and another one is known as DC motor.A DC generator converts mechanical power (ωT) into DC electrical power (EI), whereas, a DC motor converts d.c electrical power into mechanical power.THEORY, CONSTRUCTION, AND OPERATION,THEORY, CONSTRUCTION, AND OPERATION 1.

  • Construction and Principle of Operation of the Shunt DC Motor

    The DC Shunt-wound motor, running on Direct current, has its field windings placed in parallel to the armature. In Electrical terms, parallel is generally denoted as shunt. That is the reason behind naming it a DC Shunt motor. Same voltage is applied to both shunt winding and armature in this motor. This parallel configuration allows independent path of current for field winding and armature.Working or Operating Principle of DC Motor Electrical4U,Jul 11, 2019· The DC motor is of vital importance for the industry today and is equally important for engineers to look into the working principle of DC motor in details that we have discussed in this article. To understand the operating principle of DC motor we need to first look into its single loop constructional feature.

  • Differentiating Between DC and AC Motors Electrical

    Compound machines can be further classified as cumulative and differential. Cumulative and differential machines can be further classified as long shunt and short shunt. As you can see, there are a variety of electrical configurations for a DC machine. For the purpose of this article, we will stick with the series- and shunt-wound DC motor.Construction and Principle of Operation of DC Series Motor,DC series motor works on the direct current converting electrical energy to mechanical energy. It works on the principle of generation of rotational motion when a conductor placed in magnetic field carries current. The interaction of the generated magnetic field and external magnetic field results in the rotational movement. In this motor field winding is placed in series to the armature.

  • 4 Types of DC Motors and Their Characteristics

    Series DC motor. In a series DC motor the field is connected in series with the armature.The field is wound with a few turns of large wire because it must carry the full armature current. A characteristic of series motors is the motor develops a large amount of starting torque. However, speed varies widely between no load and full load.4. DC MOTORS NUS UAV,4.
