Advantages of Brushless DC Motors

Brushless DC motor is one of synchronous motors, whose rotor speed is affected by the speed of the rotating magnetic field of its stator and the number of poles of the rotor. Brushless DC motors not only have a series of advantages of AC motors, such as simple structure, reliable operation and convenient maintenance but also have features such as high operating efficiency and good speed regulation performance of DC motors. The most important part of a brushless DC motor is its control structure, whose driver can control the rotor to maintain a certain speed, and its performance is more stable. Brushless DC motor is a low-power motor that uses electronic commutation and is widely used in modern production equipment, instrumentation and household appliances.

Peaco Support brushless DC motors have many advantages.

1. High efficiency

The efficiency of a traditional DC motor is generally about 75%, while the efficiency of a general brushless DC motor can reach more than 96%. With high efficiency, the energy conversion rate of the electrical energy into the rotating mechanical energy of the motor is high, namely, the motors are energy saving. Compared with traditional motors, brushless motors can save more than 20% energy.

2. Long service life

Generally, traditional brushed motors need to be replaced at intervals due to the abrasiveness of the carbon brushes and have frequent maintenance. However, brushless DC motors generally have a service life of more than 20,000 hours and can be used for more than 5 years under normal operating conditions. Thus, the lifespan of the DC brushless motors is 5 times that of the traditional motors.

3. Low noise

since brushless DC motors have simple structure, their parts can be installed precisely, their operation is relatively smooth and the operating sound is below 50db. Therefore, many medical equipment adopt the brushless DC motor. However, traditional motors need to replace the carbon brushes, which cannot be sealed and the wear of the carbon brushes causes frictional noise with above 60db, which cannot meet the requirements of high-quiet equipment.

Peaco Support brushless DC motors also have intelligent control performance, such as low speed, high torque and communication control, which are increasingly popular among equipment manufacturers. With the popularization of smart applications among consumers, brushless DC motors will be widely used in industrial automation.

Why My Torque Sensor Reading is Unstable?

Torque sensors often have unstable output signals during use. But the torque sensor testing is qualified after the production. What is the reason for this? In fact, there are many reasons for the unstable signal of the torque sensor during use and the common ones mainly include the following three aspects. The torque sensor is not installed properly and the axis is not parallel, which will cause the signal output to be unstable. The torque sensor is easy to be damaged if it is in this state for a long time. The power supply voltage is unstable. Our torque sensors are generally powered by a dual voltage of plus and minus 15V and 24V or other voltages. Unstable power supply voltage will also cause unstable output signals. Interference from other machines next to the torque sensor. For example, if there is a frequency converter next to the torque sensor, it is easy to cause the output signal to be unstable. The solution is to add a 1:1 isolation transformer in front of the power supply of...

Electric Linear Actuator

How does an electric linear actuator work? Here is the working principle of electric linear actuator. The electric motor drives a pair of screw nuts after gear deceleration. The rotary motion of the motor is turned into linear motion, and the actuator action is completed with the help of forward and reverse rotation of the motor. Such mechanisms can complete the rotation, shaking and other complex actions. By changing the length of the lever force arm, the stroke can be increased. Electric linear actuator is a general-purpose auxiliary drive device, which can be widely used in medical, furniture, home, electronics, electric power, machinery, metallurgy, transportation, mining, petroleum, chemical, lifting, transportation, construction, grain and feed processing and other industries. The linear actuator features energy-saving and environmental protection, reliable performance, sensitive action, smooth operation, same push and pull force, good environmental adaptability, etc. Additional...
