Advantages and Disadvantages of Brushed Motors

Introduction: In the world of electric motors, there are various types available, each with its own advantages and disadvantages. One such type is the brushed motor, which has been widely used in a variety of applications. In this article, we will explore the features and benefits of brushed motors, specifically focusing on the LeanMotor brand. So, let's dive in and discover why brushed motors are a popular choice!

1. The LeanMotor Brand: When it comes to brushed motors, the LeanMotor brand stands out as a reliable and trusted name in the industry. Known for their quality craftsmanship and innovative designs, LeanMotor has been delivering top-notch brushed motors to meet the diverse needs of customers.

2. Rotational Mechanism: The brushed motor operates using a sliding contact rectifier mechanism, which consists of brushes and a commutator. This mechanism allows for the switching of armature current, enabling the motor to rotate.

3. No Additional Driver Required: One of the significant advantages of brushed motors is that they do not require any additional driver devices. This means that you can directly connect the motor to a power source, simplifying the overall system setup.

4. High Starting Torque: Brushed motors are known for their high starting torque. The torque is directly proportional to the armature current, making brushed motors ideal for applications that require a significant initial force. This feature is particularly beneficial in medium to high-speed applications.

5. Rotational Speed: The rotational speed of a brushed motor is directly proportional to the voltage applied to the armature. However, as the load torque increases, the speed decreases. It is important to note that the maximum speed achievable is limited by the wear and tear of the brushes and commutator, typically ranging from a few hundred to a few thousand revolutions per minute (rpm).

6. Reversing Direction: Reversing the direction of a brushed motor is as simple as changing the polarity of the pin voltage. This flexibility makes brushed motors highly versatile in applications where bidirectional rotation is required.

7. Control Flexibility: To maintain a constant rotational speed, brushed motors require speed control, which can be achieved using feedback from a speed sensor. Additionally, torque control is relatively easy with brushed motors since torque is directly proportional to the current. This control flexibility allows for precise and efficient operation in a wide range of applications.

8. Affordable Price: Compared to other motor types, brushed motors are relatively inexpensive. While coreless motors may be slightly more expensive due to magnet upgrades, brushed motors remain a cost-effective choice for various applications.

Conclusion: In conclusion, brushed motors, particularly those offered by LeanMotor, have several advantages that make them a popular choice in the industry. Their high starting torque, ease of control, affordability, and flexibility in reversing direction make them suitable for a wide range of applications. However, it is essential to consider the limitations imposed by the wear and tear of brushes and commutators. Despite these limitations, brushed motors continue to be a reliable and cost-effective option for many industries. So, whether you need a motor for your robotics project, home appliances, or automotive applications, LeanMotor's brushed motors are definitely worth considering!
