Oct 07, 2019 · So, these machines are used at a place where there is a requirement of single directional power. These machines are used in batteries to generate unidirectional power. This article gives an overview of a DC machine, which includes construction, working, parts, EMF equation, types, its losses, and appliions.
Sep 09, 2019 · Unlike series DC motors, shunt DC motors excel in constant speed appliions due to their feedback design. They can keep a precise RPM and torque, even under varying load conditions, making them useful for woodworking equipment, grinders, or any other rotating power tool where a user will be pushing against rotation.
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 generator can be run as a dc motor and viceversa. Read: Working of DC Motor. All dc machines have five principal components.
Jul 16, 2021 · In dc machines electromagnets are used for producing necessary flux. Whenever these field windings carry current, pole cores get electromagnetized and produce flux. Construction material: Copper is used for the construction of field windings. 4Armature: The armature is the rotating part of the machine. It mainly has two parts:

Is DC generator and motor have same construction??? 3. Main construction diagram 4. Main parts The two major parts required for construction : 1.
Oct 14, 2020 · DC Generator Generator principle. An Electric generator is a machine that converts mechanical energy into electrical energy. It is based on the principle that whenever flux is cut by a conductor, an emf is induced which will cause a current to flow if,the conductor circuit is closed.
Ans 1. Same as number of poles. Explanation: In a lap winding, the number of parallel paths, a, is always equal to the number of poles, p, and also to the number of brushes. The number of parallel paths in a DC machine depends on the type of armature winding used.
