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 were … 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 rotation of the armature is referred to as the commutating plane. In this diagram the commutating plane is shown for just one … 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 … See more DC motors Brushed DC motors are constructed with wound rotors and either wound or permanent-magnet stators. Wound stators The field coils have traditionally existed in four basic formats: See more A DC motor's speed and torque characteristics vary according to three different magnetization sources, separately excited field, self-excited field or permanent-field, … See more Shunt wound motor With the shunt wound motor's high-resistance field winding connected in parallel with the armature, Vm, Rm and Ø are constant such that the no load to full load speed regulation is seldom more than 5%. Speed control … See more WebElectric Motors. We provide a full line of brushed and brushless motors with sizes and outputs for all types of aerospace and defense applications.
