The controller may be configured with a series-wound or a separately excited DC traction motor. In the series-wound motor/controller configuration, the field and the armature current are separately controlled. In the separately excited motor/controller configuration, the field of the motor is ...
The magneticpoles of a DC motorare fitted onto the yoke’s inner wall with screws. They consist of two parts: the pole core and the pole shoe. The pole core, with a small cross-sectional area, holds the pole shoe over the yoke. The pole shoe, with a larger cross-sectional...

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 vice-versa. In this article, we will explain the con...
发明人: JC Bastholm 摘要: The drive unit has a pair of controllers for compensating the losses occurring in a direct current (DC) motor and removing the voltage ripples, respectively. Independent claims are also included for the following: (1) control unit; and (2) adjustable furniture.收藏...
A stationary part like a stator is one of the parts in DC motor parts which includes the field windings. The main function of this is to get the supply. Rotor The rotor is the dynamic part of the motor that is used to create the mechanical revolutions of the unit. ...
This paper presents the model construction of a brushless DC motor via MATLAB/SIMULINK and FPGA control, so that one can evaluate the performance of the BLDC motor control with various control schemes using MATLAB/SIMULINK. The constructed model consists of a BLDC motor dynamics block, a Hall-se...
The working principle of a DC Shunt Motor is, whenever a DC motor is turned ON, then DC flows throughout the stator as well as the rotor. This current flow will generate two fields namely the pole as well as the armature. In the air gap between armature and field shoes, there are tw...
Carbon brushes in DC machine: Brushes are used to collect the current due to the induced emf from the armature coils in a DC generator. When a brush is at any particular segment, it shorts out that particular coil and draws current from the rest of the coils, ...
Synchronous motors face the challenge of not self-starting due to the absence of uni-directional torque. Thus, several methods are used to start a synchronous motor such as installing a damper winding, using pony motors, using an exciter as a DC motor, or connecting it with a DC generator....
