A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems … See more The following graphics illustrate a simple, two-pole, brushed, DC motor. When a current passes through the coil wound around a soft iron core situated inside an external magnetic field, the side of the positive pole … See more In a dynamo, a plane through the centers of the contact areas where a pair of brushes touch the commutator and parallel to the axis of … See more Generally, the rotational speed of a DC motor is proportional to the EMF in its coil (= the voltage applied to it minus voltage lost on its resistance), and the torque is proportional to the current. Speed control can be achieved by variable battery tappings, variable … See more To extend a DC motor's service life, protective devices and motor controllers are used to protect it from mechanical damage, excessive moisture, high dielectric stress and high temperature or thermal overloading. These protective devices sense … See more DC motors Brushed DC motors are constructed with wound rotors and either wound or permanent-magnet stators. Wound stators See more A DC motor's speed and torque characteristics vary according to three different magnetization sources, separately excited field, self-excited field See more Shunt wound motor With the shunt wound motor's high-resistance field winding connected in parallel with the … See more WebBrushless DC motors, known as BLDC motors, are a permanent magnet synchronous electric motor driven by direct current and an electronically controlled commutation system, the process of producing rotational torque by changing phase currents. They are also referred to as trapezoidal permanent magnet motors. WebMedia in category "Permanent magnet DC electric motors".
