outrunner bldc Structure
- Rotor (Outer Part): Located on the outside, it contains permanent magnets that interact with the stator's magnetic field to produce rotation.
- Stator (Inner Part): The stator, which is stationary, holds copper windings arranged in coils that generate a rotating magnetic field when energized.
- Bearings: High-quality bearings support the rotor and ensure smooth, frictionless rotation around the stator.
- Electronics: The Electronic Speed Controller (ESC) manages the timing and current flow to the stator windings, controlling the motor's speed and torque.
- Cooling: Ventilation holes in the rotor housing help dissipate heat, preventing overheating to maintain optimal performance.
- Mounting Hardware: The motor includes a mounting base and connectors for secure attachment to the application and electrical connections.

FAQ
How does the efficiency of outrunner brushless motor compare to inrunner motors?
Outrunner motors generally have higher torque efficiency, making them suitable for applications requiring high power at lower speeds. Inrunner motors, on the other hand, are more efficient at higher speeds.
Can outrunner bldc motor be used in high-speed applications?
While outrunner motors excel in high-torque, lower-speed applications, they can still be used in high-speed applications, but inrunner motors are typically more suited for such tasks.
How do I choose the right brushless dc outrunner motor for my project?
Consider the required torque, speed (RPM), size constraints, and cooling needs of your application. Matching these parameters with the motor’s specifications will help you choose the right one.
Are outrunner brushless motors waterproof?
Not all outrunner motors are waterproof. If you need a waterproof motor, look for models specifically designed for wet or marine environments.
How do outer rotor brushless dc motor handle heat dissipation?
The rotating outer shell of outrunner motors helps in effective heat dissipation, allowing them to maintain performance and longevity even under continuous use.
What power sources are compatible with outrunner brushless motors?
They are typically compatible with a variety of power sources, including batteries and DC power supplies, depending on the voltage and current requirements of the motor.
Is it possible to control an micro outrunner brushless motor with a standard ESC (Electronic Speed Controller)?
Yes, but it’s important to match the ESC specifications with the motor’s voltage and current requirements to ensure optimal performance and avoid damage.
What is the typical efficiency range of an outrunner brushless motor?
The efficiency of outrunner brushless motors can vary but generally ranges from 80% to 90%, depending on the design and application.
