The combination of brushless motor and gearbox, also known as brushless gear motor or brushless gear motor, has been widely used in many fields. This combination fully utilizes the advantages of brushless motors and gearboxes, achieving efficient, stable, and low-noise power transmission. The following is a detailed analysis of the brushless motor with a gearbox:
1、 Definition and Structure
Brushless reduction motor is achieved by adding a reduction gearbox on the basis of brushless motor. A gearbox is usually composed of a combination of multi-stage gears, which reduce the output speed of the motor and increase the output torque by changing the transmission ratio of the gears. In this way, brushless deceleration motors can meet the needs of low-speed and high torque applications.
2、 Working principle
The brushless motor drives the permanent magnet rotor to rotate by reversing the current through an electronic commutator. The gearbox reduces the speed of the rotor through gear meshing and transmits torque to the output shaft. During this process, the gears inside the gearbox will rotate according to a specific transmission ratio to achieve the desired reduction effect.
3、 Characteristics and advantages
Efficient and energy-saving: Brushless motors themselves have high energy conversion efficiency, while gearboxes can maintain high transmission efficiency while reducing speed. Therefore, brushless reduction motors have high overall efficiency and can achieve energy conservation and consumption reduction.
High torque output: Through the deceleration effect of the gearbox, the output torque of the brushless motor is significantly increased. This enables brushless deceleration motors to drive heavier loads or achieve higher working accuracy.
Low noise and low vibration: The structural design of brushless motors and gearboxes takes into account the requirements of noise reduction and shock absorption. Therefore, the noise and vibration generated by brushless reduction motors during operation are relatively low, making them suitable for situations that require a quiet environment.
Long lifespan: Brushless motors do not have vulnerable parts such as mechanical commutators and brushes, therefore they have a longer service life. Meanwhile, the gears inside the gearbox are also made of wear-resistant materials and high-precision machining processes to ensure their long-term stable operation.
High precision control: Brushless deceleration motors can achieve high-precision speed, position, and torque control through electronic controllers. This makes it have broad application prospects in fields such as industrial automation and robotics.
