Outer rotor brushless dc motor a rotor inside and a much higher moment of inertia of the rotor (on the main quality is concentrated in the shell of the rotor), so the speed slower than inner rotor motor, which can be used to directly drive the load, and eliminate the mechanical retarding mechanism, especially suitable for low speed high torque, small volume, high output power.

Product Description
The 90EL series external rotor brushless motor is a more powerful motor with higher torque and power output, suitable for industrial applications that require greater load capacity.
The Outer Rotor Brushless Motor is an engineering triumph that has been gaining significant attention in the field of electric propulsion. This motor is particularly known for its high torque outrunner motor design, which is a configuration where the stator is placed in the center and the rotor surrounds it. This arrangement allows for a larger surface area of the rotor to interact with the magnetic field, thereby producing a substantial amount of torque.
The high torque outrunner motor is a popular choice for applications where a high starting torque is required, such as in electric vehicles and industrial machinery. The design of the motor ensures that it can deliver a high torque at standstill, which is crucial for applications that need to overcome static friction or heavy loads at the onset.
Furthermore, the high torque low rpm electric motor is another key aspect of the Outer Rotor Brushless Motor. This characteristic is highly beneficial for situations where maintaining a consistent and strong force over a longer period is essential. The high torque at low speeds allows for better control and efficiency, particularly in scenarios where rapid acceleration is not the primary concern.
The term "outrunner motor" is often used to describe this type of motor due to the rotor's position. The outrunner motor is favored for its efficiency and power density. It is often used in high-performance applications where a compact size is necessary, yet a high output of power and torque is required. This makes the outrunner motor a staple in the design of drones, go-karts, and even certain types of electric bicycles.
The high torque outrunner motor is the core of the Outer Rotor Brushless Motor's power. It delivers an impressive amount of torque directly to the wheels or propellers, which is ideal for applications that require a strong and immediate response. This makes it a favorite among enthusiasts and professionals alike who demand the utmost in performance from their electric motors.
The high torque low rpm electric motor aspect of the Outer Rotor Brushless Motor is particularly noteworthy. It provides a significant advantage in scenarios where constant power output is more important than speed. This makes the motor not only powerful but also highly efficient, as it can maintain a high torque output without consuming excessive amounts of energy.
