Advantages of DC Motors & DC Speed Controls
DC Motors & Drives are considered the best suited for electrical traction applications. That means that it is ideal for driving heavy loads in starting conditions. For DC series motors, the starting torque is as high 500% of the actual value of the operating torque. This is why we have several motors in use in applications such as: Extruders, Mills, Trains, Press, Cranes, etc.
DC Motors give you better Speed Control over a Wide Range
Another feature of the DC motor & Drive that makes it attractive for industrial purposes is the fact that it offers you a wide range of speed control. This is not only when it is above the rated speed, but also below the rated speed. One way by which this is done in DC shunt motors is either via armature control method or field control method. Hence, it is widely employed in both Rolling Mills and Paper Mills.
DC Motors are devoid of the Harmonic Effect
One of the major disadvantages of induction motors is the harmonics. This doesn’t just cause inefficiencies and losses; it also shortens the lifespan of the motor. However, DC motors do not have this issue, the harmonic problem is eliminated.
DC Motors give you quick control over the Motors
Fast and accurate control of motors has been hitherto impossible with conventional AC motors. This is especially true for applications that require the immediate start, stop, and reverse operation. DC motors, however, solve this problem properly.
DC Motors are ideal for Low-Cost Operation
In comparison with induction drives used for heavy-duty operations, DC motors considerably save cost.
The Electronics required are Minimal
When you compare a typical DC drive with an AC drive, you will observe that the power electronics circuitry is less complex. Similarly, DC drives can run on several different types of power source.
DC Motors Offer Improved Speed Regulation
DC motors are much more popular due to the flexibility it offers in terms of speed regulation when you compare it to AC motors. When it comes to higher specific speed control, DC motors are the best choice, they have being in used since late 1800's and they have done an excellent job.
