What is the function of a brushless DC motor and what are its uses

In this issue, I will introduce you to the functions and uses of brushless DC motors, I hope it will be helpful to you.

1. Visualization of state changes and power consumption

● Monitoring

The load, speed, temperature, and other status of the motor and drive can be displayed on the panel, or the value can be output to the upper level.

● Warning/information signals

If the load, speed, etc. exceeds the preset value, a signal is output before an alarm is issued.

● Alerts

When there is an abnormality in the motor and driver, an alarm is output and the motor stops running.

Second, the common use of DC motors

Brushless motors can also be used in a variety of different stations and can be used in a variety of applications.

1. Handling

Positioning applications: Most industrial control and automation applications fall into this category, and energy transfer is often accomplished in such applications;

Therefore, there are special requirements for the dynamic response and torque of the speed, and the requirements for the controller are also high.

Process control, machinery control, and transportation control are many applications in this category.

Handling of work objects of different weights

●Stable speed can be maintained during load fluctuations

●Uniform torque from low speed to height

●The error of the stop position is small

Dual-axis parallel, speed synchronization

● Simple synchronization of two conveyor belts

●Simple synchronization of conveyor belt busbars

2. Stirring · pump · take water

Continuous load application: mainly in the field that requires a certain speed but does not require high speed accuracy, such as water pumps, water intake, agitation, fans, pumps, hair dryers and other applications.

●Stable speed even if there is a change in viscosity

●Small motor, space-saving

●Energy saving, low heat generation, instantaneous forward and reverse rotation

3. Push and push

Variable load applications: mainly applications where the speed needs to vary within a certain range, and there is a higher demand for motor speed characteristics and dynamic response time characteristics. Dryers and compressors in household appliances such as those are good examples.

●Torque limit prevents breakage

●Monitoring of load volume

●Only for products that can use the torque limiting function
