For BLDC2418 Brushless Motor You May Want to Know

1.Q:What's the meaning of motor type name:BLDC2418?
   A:"BL" means brushless; "DC" means direct current;"2418" means 24mm diameter and 18mm motor length not include terminal and shaft length.

2.Q:Is a 310 brushless motor same as BLDC 2418 motor ?

   A:Yes,brushless motor is other name of BLDC2418.Different factory may has different name system.

3.Q:Which is better motor: Brushless 310 motor or brushed 310 motor? How can I choose for my product?

   A:There is no absolute good or bad between brushed and brushless motors — it depends on which best fits your application.

If you prioritize cost-effectiveness, high volume, and low lifespan requirements → choose brushed motor
If you prioritize stability, long life, low noise, and energy efficiency → choose brushless motor

4.Q:I can provide you with the motor model number, but I cannot offer specific parameters. Can you still give me some advice?
   A:Each motor manufacturer may have its own naming system, so based on the model number alone, it’s difficult for me to recommend a suitable motor.If you can provide parameters such as voltage, speed (RPM), current, torque, shaft length, and motor dimensions, I can help suggest a motor solution that best fits your needs.Alternatively, you can send us a sample, and we can replicate the exact same motor for you.

5.Q:Is the size of brushed 310 motor same as 310 brushless motor ?

   A:They are not the same size internally or mechanically, even if they are in the same "310" series. Always check detailed mechanical drawings before replacing or designing with either.

Advice for Choosing Suitable 310 Motor 

To choose between a brushless 310 motor and a brushed 310 motor, you need to evaluate their differences based on your product’s application, performance requirements, and cost sensitivity.

Basic Comparison: Brushed vs. Brushless 310 Motor

When to Choose Brushed 310 Motor

Choose this if your product:

Has a tight cost limit
Will be used intermittently or for short cycles
Doesn’t require long lifespan (e.g., disposable items or low-use devices)
Needs a simple power circuit (plug-and-play)

Examples: Small toys, beauty massagers, low-end electric shavers, throwaway gadgets.

When to Choose Brushless 310 Motor

Choose this if your product:

Needs high reliability, long life, or continuous use
Must be quiet or efficient
Can accommodate a motor driver (ESC)
Operates in environments sensitive to dust or wear

Examples: Drone fans, electric toothbrushes, high-end mini pumps, continuous-use robots, or smart appliances.

Additional Considerations

Space Constraints: Brushless motors may require a separate or built-in driver board.

Battery Life: Brushless motors are better for battery-powered products due to higher efficiency.

Torque & Speed Needs: If you need precise speed/torque control, brushless motors work better with ESC feedback.

How to Decide for Your Product

Answer these three key questions:

What is the expected duty cycle? (occasional vs. continuous)

What is your budget per unit including control board?

Does your customer care about noise, durability, or efficiency?
