The Technology Of Intrunner Rotor BLDC Motors
An inrunner rotor BLDC motor follows the traditional motor layout. The rotor with magnets is positioned at the center and rotates inside the surrounding stator windings. This conventional structure defines its high‑speed characteristics and sets it apart from outrunner motors, which rely on a rotating outer shell.
The smaller magnetic radius enables higher rotational speed and faster dynamic response. The enclosed rotor reduces aerodynamic drag, allowing the motor to reach significantly higher RPM. The fixed outer stator provides structural rigidity and supports precise control, though torque density is generally lower compared to an outrunner design.
Inrunner rotor BLDC motors excel in high‑speed, compact, and precision‑control applications. They are widely used in power tools, medical devices, robotics actuators, micro‑mechanisms, and small electric systems. Their characteristics align well with applications that require fast response, stable speed control, and efficient operation within limited space.
Common DC Motor Designs
No matter which DC motor technology is used, certain form factors and design features are common across many industries. These shared elements help guide the selection of the best motor solution. Below are some examples to help describe your ideal choice.
Terminals and connector pins
Connecting the motor to the application is essential. We usually use soldered pins, spring pad connectors, and integrated connectors for this purpose.
Leads and connectors
Wires and leads are commonly used to connect motors in applications. We provide various lengths, gauges, and pre-installed connectors.
Frame modifications
Securing motor frames to your application can be achieved in several ways. Custom fastening points and brackets are often utilized.
EMI filters and backpack PCBs
Operating motors generate EMI electrical noise. This can be reduced by installing filters, which can be either PCB-based or wire-based.
Shaft modifications
The motor must connect mechanically to your product. We can create custom shafts and pre-install gears, bushes, and bosses.
Motion controllers
A small PCB attached to the back of a DC motor can convert it into a precision servo at a fraction of the cost of a similar off-the-shelf unit.
