The speed control of a DC motor is the device that controls the speed of a DC motor. A DC is very important and is widely used in our daily lives. The DC motor turns the electrical energy into mechanical energy. This is used to perform various tasks, thus creating the need for speed control. And the device to regulate the DC motor’s speed is known as the DC motor’s speed control. One can either control the speed manually or use an automatic device to control the speed. There are three ways in which one can control the speed, flux control, armature control and voltage

Top 10 Best Speed Control of DC Motors in India
Features of DC Motor
- The speed control of DC motors comes with different voltage inputs.
- Similarly, the output also varies by different brands.
- They have different prices and shapes as well.
- Most of the controllers use the technique of Pulse-Width-Modulated PWM.
- This provides different pulses to the motor driver which controls the voltage.
- Through this power, the loss can be minimized.
- Speed control of the DC motor comes in multi-colour as well.
- This helps to identify each part of the device.
Types of DC Motors
- There are different types of speed control of DC motors.
- For example, Speed control for DC shunt motors.
- Speed Control of DC series motors.
- Speed control for parallel series motors.
- The devices use different methods to control speed.
- Some use flux control methods.
- Some armature control, some use voltage control methods.
- While there are some which use paralleling field coil method and tapped field control method.
How to use DC Motor?
- Speed control of the DC motor is very necessary.
- It is applicable in various applications for example as a light dimmer, in DC fans, to control the speed of robotic vehicles like RC boats etc.
- Connect the device with the motor.
- Make sure about the input and output terminals.
- Adjust the voltage. Connect it with a power supply.
- You can adjust the speed through the controller.
Buyer’s guide for DC Motor?
- When buying the speed controller look for the nominal voltage of the DC motor and the speed control of the DC motor simultaneously.
- A DC motor comes in various voltage ranges so it is important to select a suitable controller.
- The next thing to consider is continuous current.
- DC motors use a certain amount of current, so it is better to choose the controller which suits the specific amount of current.
- It would be just a waste to use a low current controller with a high current motor.
- Similarly, a high current motor will burn the low current controller.
- Next is what kind of control method you are going to use. Choose which suits your motor.
