If you are talking polarity. DC motors automotive application run poss to neg. But any dc motor can reverse by changing polarity.
Its an electric component that resists the flow of electrical current. Resistors are used to control the flow of current to the blower motor so that different speeds can be achieved
To reverse the direction of current in a motor, the current conducting wires must be switched. By changing the configuration of the wires, the flow of current through the motor's coils can be reversed, thereby changing the direction of rotation of the motor.
Yes. It is identical to the line current.
Excessive resistance (drag), will cause motor to draw more amps (current flow) to operate.
Inrush current is the initial surge of current that occurs when an electric motor is first powered on. This current can be several times higher than the motor's normal operating current and lasts for a brief period until the motor reaches its operating speed. The high inrush current is primarily due to the low impedance of the motor at startup and the absence of back electromotive force (back EMF) that normally opposes the current flow once the motor is running. Managing inrush current is important to prevent damage to electrical components and to ensure proper operation of motor control systems.
If 200 amperes flow from the positive terminal of the battery to operate the starter motor, the same amount of current, 200 amperes, will flow back to the negative terminal of the battery. This is due to the principle of conservation of charge, where the current flowing out of the battery must equal the current returning to it in a closed circuit. Therefore, both the outgoing and returning current will be equal at 200 amperes.
In a motor, electrical current enters through the brushes, which are in contact with the commutator. This flow of current energizes the motor's windings, generating a magnetic field that interacts with the stator's magnetic field. This interaction produces torque, causing the rotor to spin and ultimately driving the mechanical load connected to the motor. The design of the brushes and commutator allows for the continuous transfer of current, enabling smooth motor operation.

A series DC motor has to have a starting resistor to limit the current flow before the speed builds up.
The starting current is high because the motor's rotor winding has very low resistance. It's similar to a transformer with a shorted secondary windings. As the motor accelerates,the back emf increases which resist the flow of current in the rotor winding. Hence,the current drop to the rated full-load value.
Motors overheat due to excessive current, not necessarily voltage. Normal voltage can cause a motor to overheat if it is stuck (not spinning). The problem is not usually the voltage, but whatever is causing excessive current flow (usually because the motor is not spinning like it is supposed to).
A DC motor is an electric motor that turns on the application of a DC current. A DC Servo motor is similar but it produces a DC current from a mechanic movement of the armateur or may also produce small movement from the application of low current.. An example of a servo motor is as was used in steering gears and auto pilots. The physical turning of the wheel either caused a current to flow or caused an inbalance in the electrical systems, this causes a counter action to restore the original position.
