Applications

Frameless Brushless DC Motors are designed for seamless integration into systems where space, weight, and precision are critical. Due to their high efficiency, compact design, and reliability, these motors are commonly used in robotics, drones, medical devices, and industrial automation. 

Tips: How is torque density calculated for frameless BLDC motors?

Torque density for frameless BLDC motors is calculated by dividing the motor's maximum torque by its volume. This value measures the amount of torque the motor can produce relative to its size and is a critical factor in applications where space and weight are limited. 

The formula is:  Torque Density=Maximum Torque / Motor Volume 

Where:

• Maximum Torque is the highest torque the motor can generate.
• Motor Volume is the total physical space occupied by the motor's components (stator, rotor, and windings).
