Brief Overview of a 12V DC Motor
November 24th, 2015
A DC motor is any motor within a class of electrical machines whereby direct current electrical power is converted into mechanical power. Most often, this type of motor relies on forces that magnetic fields produce. Regardless of the type, DC motors have some kind of internal mechanism, which is electronic or electromechanical. In both cases, the direction of current flow in part of the motor is changed periodically.
The speed of a DC motor is controlled using a variable supply voltage or by changing the strength of the current within its field windrings. While smaller DC motors are commonly used in the making of appliances, tools, toys, and automobile mechanisms, such as electric car seats, larger DC motors are used in hoists, elevators, and electric vehicles.
A 12v DC motor is small and inexpensive, yet powerful enough to be used for many applications. Because choosing the right DC motor for a specific application can be challenging, it is important to work with the right company. A prime example is METMotors, which has been creating high-quality permanent magnet DC motors for more than 45 years.
Selecting the Right Motor
As part of the selection process for choosing the right DC motor, the professionals with METMotors will first learn about your exact application and then consider several different characteristics and specificationsto ensure you end up with the best product possible.
One characteristic of a 12v DC motor is the operating voltage. When a motor is powered by batteries, low operating voltages are typically preferred since fewer cells are required to obtain the specified voltage. However, at higher voltages, electronics to drive a motor are typically more efficient. Although operation is possible with volts as low as 1.5 that goes up to 100, the most common are the 6v DC motor, 12v DC motor, and 24v DC motor.
Other key specifications of a 12v DC motor that METMotors can assist with include the operating current, speed, torque, and power. Although a DC motor at this voltage is ideal for many applications, the company will consider everything prior to making the final recommendation.
