Brushless gear motor is a modern motor technology that has been widely successful in a variety of applications. This brushless motor offers higher efficiency, lower maintenance costs, and a longer lifespan than traditional brushed motors. Brushless.com will provide you with an overview of how brushless gear motors work, their advantages, and prospects to help you better understand this important motor technology.
Brushless gear motors are a type of brushless motor that has a reduction mechanism for reducing the speed of the output shaft, thereby increasing the output torque. Brushless gear motors are important in many applications because of their ability to provide precise rotational control, efficient energy utilization, and reliability.
Structure
- Stator: The stator is the stationary part of a brushless gear motor and usually contains the coils and the electronic controller. An electric current is passed through the stator coils to create a rotating magnetic field.
- Rotor: The rotor is the rotating part of a brushless gear motor and is usually made of permanent magnets. The permanent magnets on the rotor interact with the rotating magnetic field of the stator, which generates a torque that pushes the rotor to rotate.
- Reduction Mechanism: The reduction mechanism is used to reduce the speed of the output shaft and increase the output torque. This usually involves a gear system, allowing brushless gear motors to be adapted to the needs of different applications.
- Sensors: Some brushless gear motors are equipped with sensors to monitor the position and speed of the rotor. These sensors provide feedback to help the electronic controller better control the motion of the brushless gearmotor.
Principle of Operation
An electric current passes through the stator coils, creating a rotating magnetic field. This rotating magnetic field is precisely controlled by the electronic controller to make the motion of the brushless gearmotor more precise. Permanent magnets on the rotor interact with the rotating magnetic field of the stator to generate torque that pushes the rotor to rotate. The reduction mechanism reduces the speed of the output shaft and increases the output torque, adapting the motor to the needs of different applications. Sensors monitor the position and speed of the rotor and relay the feedback to the electronic controller. This allows for more precise control of the brushless gearmotor, such as closed-loop control for highly precise rotation.
