Frameless DC motors are becoming increasingly popular in automation and robotics. These motors have several advantages over conventional motors, especially in terms of performance, efficiency and versatility. In this article, we will explore the differences between frameless DC motors and brushless motors.

What is a frameless DC motor?

A frameless DC motor is a motor consisting of a rotor and a stator, but without a frame. These motors are usually designed for high torque and low speed applications. The absence of a frame makes these motors more compact, lighter and more efficient than conventional motors. Frameless DC motors are ideal for applications where space and weight are key considerations.

What is the difference between a frameless DC motor and a brushless motor?

There are several differences between frameless DC motors and brushless motors. Let's look at some key differences.

Rotor and stator windings:

Frameless DC motors have a direct winding between the stator and the rotor, while brushless motors use separate windings on the stator and rotor. This means that frameless DC motors are more efficient and have a higher power density than brushless motors.

Transform:

Frameless DC motors use brush commutation rotors, while brushless motors use electronic commutation. This means that frameless DC motors are simpler and less expensive than brushless motors.

Torque and speed:

Frameless DC motors are typically designed for high torque, low speed applications, while brushless motors are designed for high speed, low torque applications. This means frameless DC motors are better suited for applications that require high forces, such as robotics, while brushless motors are better suited for applications that require high speeds, such as drones.

Size and weight:

Frameless DC motors are usually smaller and lighter than brushless motors because they do not require a frame. This makes them ideal for applications where space and weight are key considerations.

Frameless DC motors have several advantages over brushless motors, especially in terms of efficiency, simplicity, and compact design.
