Product Overview
Outrunner Brushless DC Motor is a type of BLDC motor where the rotor (with magnets) spins on the inside, surrounded by the stator (with windings) . From the outside, it looks similar to a traditional brushed DC or AC motor.
Here is a quick overview of its key traits
|
Feature |
Characteristic |
|
Design |
Rotor is internal, stator is external . |
|
Heat Dissipation |
Excellent (heat goes directly from stator to housing) . |
|
Speed |
Very high (ideal for applications requiring fast rotation) . |
|
Torque |
Medium (lower than outrunners at same size without a gearbox) . |
|
Robustness |
High (closed housing protects internal parts) . |
|
Inertia |
Low (rotor is small and compact) . |
Outrunner Brushless DC Motor Common Applications
Because of their high-speed capabilities and robust design, inrunner BLDC motors are a popular choice in several fields:
Drones & UAVs:
Preferred for heavy-lift and high-speed drones, especially those operating in dusty or wet conditions where a sealed motor is an advantage .
Robotics:
Used in robotic arms, exoskeletons, and automated guided vehicles (AGVs) where precision and dynamic movement are required .
Industrial Automation:
Ideal for driving conveyor belts, packaging machinery, and CNC spindles that need reliable, high-speed rotation .
Automotive & Medical:
Found in electric water pumps, medical centrifuges, and surgical tools where reliability and a long lifespan are critical .
Inrunner vs. Outrunner
The choice between an inrunner and an outrunner comes down to the needs of your specific project.
Choose an Inrunner if your project demands high speed, rapid acceleration, operation in a harsh environment (dust/moisture), or if you have a compact design space.
Choose an Outrunner if you need high torque at low speeds without a gearbox, want to save weight, or are building a cost-sensitive project.
I hope this gives you a clear picture of the inrunner BLDC motor. If you have a specific application in mind, feel free to ask for more tailored advice
