WebA DC motor is defined as a class of electrical motors that convert direct current electrical energy into mechanical energy. From the above definition, we can conclude that any electric motor that is operated using direct current or DC is called a DC motor. We will understand the DC motor construction and how a DC motor converts the supplied DC ... WebThis equation is specific to the voltage (V) across the resistance (R in ohms) being generated as a result of the resistance and current (I in amps) circulating through the resistance. As an example, a current shunt with resistance of 0.002 ohms and current of 30 Amps will result in the generation of 0.002 x 30 = 0.06 volts or 60 mV (milliVolts). WebA DC shunt motor is a variety of brushed motor that has field windings connected in parallel with the armature. Shunt wound DC motors have a lower current because of the parallel windings. A shunt motor is used for applications that require a constant torque, where the load is not significantly altered by speed, such as conveyor belts, mixers and hoists. how did apple get its name and logo
