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.

What is Wind Turbine?

The structure of a small wind power generation system is generally composed of a wind turbine , a generator, a rudder and an electrical control part. Conventional small wind turbines are mostly composed of induction generators or permanent magnet synchronous generators and AC/DC converters, batteries and inverters. In the blowing wind, the wind wheel rotates, turning aerodynamic energy into mechanical energy. The hub of the wind wheel is fixed on the generator shaft and the rotation of the wind wheel drives the rotation of the generator shaft, driving the permanent magnet three-phase generator to generate three-phase alternating current (AC). The wind speed changes continuously and the current and voltage generated by the generator also change accordingly. The generated electricity is rectified by the controller, is changed from alternating current (AC) to direct current (DC) with a certain voltage, make the battery charged. The direct current output from the battery pack is transforme...

DC Contactor Relay

A contactor is an automatic switcher that is used to connect or disconnect the AC and DC main circuits or large-capacity control circuits with loads. The contactor is to control the motor and it is also used for other electrical loads, such as electric heaters, electric welding machines, lighting equipment. Contactors are very important device in industrial field, especially the high voltage DC contactors . They can not only connect and cut off the circuit, but also have a low voltage release protection. The contactor has a large control capacity, is well suitable for frequent operation and long-distance control and is one of the important components in the automatic control system. The DC contactor relay is generally used to control the DC electrical equipment. The coil is supplied with DC current. The working principle and structure of the DC contactor are basically the same as that of the AC contactor. What is the working principle of a DC contactor? When the contactor coil is ener...
