High Torque Brushless DC Motor 8 Pole 81mm 0.65kg 4000rpm Industrial Brushless Dc Motor 4.8A 24V

 

 

Brushless DC motor itself is the electromechanical energy conversion part, it in addition to the motor armature, permanent magnet excitation two parts, but also with a sensor. The motor itself is the core of brushless DC motor, which not only relates to performance index, noise and vibration, reliability and service life, but also involves manufacturing cost and product cost. By adopting permanent magnetic field, the brushless DC motor can get rid of the traditional design and structure of the general DC motor, which can meet the requirements of various application markets, and develop towards the direction of saving copper and materials, and making it easy.

Due to the high efficiency and low calorimeter of brushless dc motor, it is very suitable for industrial machinery running continuously 24 hours a day and the load of air conditioning main engine, fan and water pump, air compressor and other industries.

Many Japanese companies have successfully applied brushless dc motor to digital cameras, miniature radio recorders, video cameras, printers, memory movers, mobile phones, as well as automotive air conditioners, vacuum cleaners, electric vehicles, heart pumps and other fields.

 

Ideal Applications for BLDC Motors

 

We’ve seen that BLDC motors offer high efficiency and controllability, and that they have a long operating life. They are widely used in devices that run continuously. They have long been used in washing machines, air conditioners, and other consumer electronics; and more recently, they are appearing in fans, where their high efficiency has contributed to a significant reduction in power consumption.

 

They are also being used to drive vacuum machines. In one case, a change in the control program resulted in a large jump in rotational speed—an example of the superlative controllability offered by these motors.

 

BLDC motors are also being used to spin hard disc drives, where their durability keeps the drives operating dependably over the long term, while their power efficiency contributes to energy reduction in an area where this is becoming increasingly important.

 

Toward Wider Usage in the Future

 

We can expect to see BLDC motors used in a wider range of applications in the future. For example, they will probably be widely used to drive service robots—small robots that deliver services in fields other than manufacturing. One might think that stepper motors would be more suitable in this type of application, where pulses could be used to precisely control positioning. But BLDC motors are better suited to controlling the force. And with a stepper motor, holding the position of a structure such as a robot arm would require a relatively large and continuous current. With a BLDC motor, all that would be required is a current proportionate to the external force—allowing for more power-efficient control. BLDC motors may also be replacing simple brushed dc motors in golf carts and mobility carts. In addition to their better efficiency, BLDC motors can also deliver more precise control—which in turn can further extend battery life.

 

BLDC motors are also ideal for drones. Their ability to deliver precision control makes them especially suited for multirotor drones, where the drone’s attitude is controlled by precisely controlling the rotational speed of each rotor.
