What Is A Frameless Motor?

Frameless motors, also known as ironless motors, are a new type of motor design that includes an inner rotor and an outer rotor, which abandons the iron core structure used in traditional motors. Compared with traditional motors, frameless motors use novel designs and materials, making the motors lighter, more efficient, quieter, and with better heat dissipation performance.

Working principle of frameless motor

The frameless motor mainly consists of two parts: the rotor and the stator. The rotor part uses permanent magnetic materials, while the stator part contains multiple windings. The magnetic field generated by the current in the winding interacts with the permanent magnetic material of the rotor part to generate rotational force. This design not only reduces energy loss, but also improves the efficiency of the motor.

Frameless motors are the core key components in the field of robotics and play an important role in robotic applications. The following is detailed information about the applications and advantages of frameless motors in the field of robotics:
