Summary of MOTORES (2ª parte): corriente continua (CC)

00:00:00 - 00:05:00

This video discusses how a continuous-current motor works. The motor is represented as a rotating spiral conductor, and the discussion focuses on the motor's power supply. A meter that measures current intensity is shown being connected to the motor, and as the current is increased, the meter decreases to zero when the current is turned off. The video explains how the motor works by breaking down the process into two functions: one where the current is constant, and the other where the current is pulsed. The constant current function is shown first, and then the pulsed function is shown. The video discusses how the motor works in detail, explaining the difference between constant voltage and constant current conditions, and how the motor is used in small cars.

• 00:00:00 This video explains how a motor that operates on continuous current works. The video starts with a simple drawing of the electrical motor, which is represented as a rotating spiral conductor. Next, the video leaves the representation of the magnetic field out of the discussion, and instead focuses on the motor's power supply, which is shown as a pole and brake. A meter that measures current intensity is shown being connected to the motor, and as the current is increased, the meter decreases to zero when the current is turned off. The video then explains how the motor works by breaking down the process into two functions: one where the current is constant, and the other where the current is pulsed. The constant current function is shown first, and then the pulsed function is shown.
• 00:05:00 In a continuous-current motor, the current flows up and down the shaft, caused by the tension in service and the external supply voltage. The motor's power comes from the difference in voltage between the applied voltage and the motor's electromotive force (EMF). When the motor is stopped, the EMF drops to zero, and the motor operates in a continuous mode. In a continuous-current motor, there are two processes going on: one is due to the rotation of the motor, and the other is due to the generator effect. The generator effect happens because the motor is turning, and according to the load and number of revolutions, it produces EMF. Small variations in voltage between the voltage in service and the EMF produce big differences in power output. In a continuous-current motor, it's important to take into account both of these processes. A continuous-current motor can operate either under constant-voltage or constant-current conditions, but the latter is more efficient. A continuous-current motor is used in small cars that have a large battery, because the small variation in voltage between the battery voltage and the EMF allows the car to run on very little electricity. In a continuous-current motor, the difference in voltage between the battery voltage
