Brushed vs Brushless DC Motors

DC motors are essential in countless applications, from household appliances to industrial automation. Two common types—brushed and brushless—offer different advantages depending on the requirements. In this guide, we will explore how each motor works, their pros and cons, and real examples using Joydo’s electronic parts such as VZ43FM1B8230001L, VG0832012, and MG16B-300-AA-00. This technical yet practical analysis is designed for engineers, buyers, and anyone sourcing reliable dc motor parts.

How Brushed DC Motors Work

A brushed DC motor uses a commutator and carbon brushes to switch the current direction in the armature windings. As electricity flows through the rotor, the magnetic interaction with the stator creates torque. The brushes physically contact the commutator, allowing for direct current switching.
Brushed motors are valued for their simplicity, low cost, and easy control with basic electronics. They are ideal for entry-level devices, toys, small appliances, and cost-sensitive industrial projects.

How Brushless DC Motors Work

Brushless DC (BLDC) motors remove the mechanical brushes and commutator, replacing them with electronic controllers. The rotor is fitted with permanent magnets, and the stator contains the coils. Electronic switching delivers current at the right time to each coil, maintaining smooth rotation.
The lack of brushes reduces wear, lowers noise, and increases efficiency. These motors excel in applications requiring long service life, low maintenance, and quiet operation—such as medical equipment, drones, and precision instruments.

Key Technical Comparison Between Brushed and Brushless Motors

When evaluating brushed and brushless DC motors, real-world performance differences become clear. For example, the VZ43FM1B8230001L brushed motor typically operates for 1,000 to 2,500 hours depending on load and maintenance, while the brushless MG16B-300-AA-00 can run well beyond 10,000 hours due to the absence of brush friction.

In terms of efficiency, brushed models like the VG0832012 usually deliver around 70–80% efficiency, whereas the MG16B-300-AA-00 brushless motor can achieve up to 90%, resulting in better energy savings and longer operating times for battery-powered devices.

Noise levels are another deciding factor. Under typical operating loads, the VZ43FM1B8230001L may generate 50–60 dB due to brush contact, while the brushless MG16B-300-AA-00 stays in the 30–40 dB range, making it suitable for noise-sensitive environments such as medical instruments or precision tools.

Maintenance requirements also differ significantly. Brushed motors like the VZ43FM1B8230001L and VG0832012 require periodic brush replacement, which can cause downtime. In contrast, the MG16B-300-AA-00 is virtually maintenance-free apart from occasional bearing lubrication.

Finally, the cost factor comes into play. Brushed motors are typically 20–40% cheaper at purchase, which appeals to budget-focused projects. However, for applications where long-term performance and minimal service interruptions matter, brushless options such as the MG16B-300-AA-00 provide better overall value.

Choosing the Right Motor for Your Application

The decision between brushed and brushless depends on the project’s priorities:

If your design requires low cost and simple control, brushed options like VZ43FM1B8230001L and VG0832012 are a good fit.
If you need long life, high efficiency, and minimal noise, brushless models like MG16B-300-AA-00 will perform better.
