Advantages of DC Motors
Are you considering a DC motor for your next project? If so, our specialists are on hand to provide you with all the help and advice you need before investing. A DC motor is powered through direct current, meaning the current flows in one direction only. Parvalux stocks a range of DC electric and geared motors in PMDC and BLDC formats.
Below are some advantages of DC motors that you should consider:
Good speed control
DC motors offer highly controllable speed. By changing the armature or field voltage it’s possible to achieve wide speed variation and with this level of controllability, DC motors offer the precision required by a wide range of industry applications.
A DC motor also offers a high starting torque, which makes it perfect for use in applications that are designed to move heavier loads, such as wiper systems and in industrial automation applications, such as conveyor systems or materials handling equipment. The consistent drive power that DC motors deliver means they’re ideal for maintaining a constant torque whilst an application is in use, making them an excellent choice for a geared motor solution.
As DC motors operate with high levels of controllable power across a range of speeds, they offer the benefit of seamless operation. In some industries, it is vital that DC motors can start and stop efficiently to cope with the requirements of the application. If you are looking for a solution that offers rapid acceleration, an option to reverse direction and start/stop efficiency, a DC motor is a good choice.
Free from harmonics
In any electric power system, a harmonic is a voltage or current at a multiple of the fundamental frequency of the system, typically produced by the action of non-linear loads such as rectifiers or saturated magnetic devices. Harmonic frequencies in the power grid can be the cause of power quality problems and harmonics in some AC motors can cause torque pulsations, resulting in a decrease in torque. DC motors are free from issues associated with harmonics.
