High Torque BLDC Outrunner Motor

External rotor motor manufacturers

A High Torque BLDC Outrunner Motor is a powerful and efficient electromechanical device designed for applications demanding substantial torque output.

It is a permanent-magnet synchronous motor (PMSM). Hence, the load is directly driven without the use of a gearbox or transmission. This reduces the number of moving parts, and thereby increases the operational lifetime and efficiency of the application.

Compared to induction motors with the same volume/weight, the peak point energy efficiency of High Torque BLDC Outrunner Motors is much higher.

Magnetic Innovations offers a wide range of standard frameless High Torque Brushless Motors with an external rotor.

Brushless outer rotor motor

Utilizing advanced brushless technology, this motor eliminates the need for brushes, resulting in reduced friction, lower maintenance requirements, and enhanced durability. The high torque capability makes it ideal for applications such as robotics, industrial machinery, and other scenarios where demanding torque requirements must be met.

High Torque BLDC Outrunner Motormotors are ideal for applications where a high positioning accuracy is needed and small size, low weight, minimum power and optimal speed control is desired.

With the use of our magnetic and thermal simulation software, our frameless high torque outrunner motors are designed to produce unmatched performance.Magnetic Innovations is specialised in the outrunner typology. Compared to inrunners, outrunner direct drive torque motors are capable of producing more torque and are more efficient. Moreover, the MI-F series are characterized by extremely low cogging and good thermal performance.

To maximize the torque of our direct drive motors, we use innovative winding configurations combined with optimized permanent magnet technology. A 3-phase sinusoidal current amplifier can be used in combination with the torque motor, which guarantees smooth rotation with low torque ripple.

The moving magnet voice coil actuators also feature very low mechanical friction, low mechanical Mechanical wear and zero stick-slip.
