A 12v DC motor is a 12-volt direct current electrical machine that converts 12 volts of direct current electrical energy into mechanical energy. Its operation is based on the law of magnetic induction, which states that when a conductor moves in a magnetic field, it produces a mechanical force.
12v DC motors are used for various purposes ranging from high-power applications to battery-operated devices. Since 12 volts is a low amount of voltage, the motors are more suitable for specific applications. Similarly, low voltage implies high current to produce high power which could result in a significant drag on the circuit. The 12v DC motors are ideal for using it in small electric appliances and electronic toys, as well as power tools and automotive applications like windshield wiper and window opener systems.
A 12v DC motor operates by running a direct current through the conductors in the motor. The magnetic field produced by the current reacts with the magnetic field coming from the permanent magnets to the sides. The motor turns because of the force created by these magnetic fields.
When selecting a 12V DC motor, consider key factors such as speed (RPM), power, torque, and efficiency. Additionally, evaluate the specific requirements of your application, including load conditions, operating environment, and performance expectations, to ensure the motor meets your needs.
Proper maintenance of the 12v DC motor would help to increase its life span. Maintenance can include cleaning the major parts of the motor, checking the insulation resistance, lubricating oil to all moving parts, and avoiding overloading the motor.
