The brushless DC motor consists of a motor body and a driver and is a typical electromechanical integration product. Brushless motors are motors without brushes and commutators (or slip rings), also known as non-commutator motors.
1, can replace the DC motor speed, inverter + inverter motor speed, asynchronous motor + speed reducer;
2, with the advantages of traditional DC motor, while canceling the carbon brush, slip ring structure;
3, can run at low speed and high power, you can save the reducer direct drive large load;
4, small size, light weight, large output;
5, excellent torque characteristics, medium and low speed torque performance, starting torque, starting current is small;
6, stepless speed regulation, wide speed range, strong overload capacity;
7, soft start soft stop, good braking characteristics, can save the original mechanical brake or electromagnetic brake device;
8, high efficiency, the motor itself has no excitation loss and carbon brush loss, eliminating the multi-level deceleration, comprehensive energy-saving rate of up to 20% to 60%.
9, high reliability, good stability, strong adaptability, simple repair and maintenance;
10, resistance to bumpy vibration, low noise, low vibration, smooth operation, long life;
11, no spark, especially suitable for explosive places, explosion-proof type;
12, according to the need for optional trapezoidal wave magnetic field motor and sine wave magnetic field motor.
Brushless DC motors are used in a wide range of applications such as automotive, tools, industrial industrial control, automation, and aerospace. In general, brushless DC motors can be divided into the following three main applications:
Continuous load application: mainly applications that require a certain rotational speed but do not require high accuracy of rotational speed, such as fans, pumps, hair dryers, etc. Such applications have low cost and are mostly open-loop control.
Variable load applications: Mainly applications where the speed needs to change within a certain range, there is a higher demand for motor speed characteristics and dynamic response time characteristics. For example, household appliances, dryers and compressors are good examples of oil pump control, electrical controllers, and engine control in the automotive industry. The cost of such systems is relatively higher.
Positioning applications: Most industrial control and automatic control applications fall into this category. Energy transfer is often done in these applications. Therefore, there is a special requirement for the dynamic response and torque of the rotational speed, and a higher requirement for the controller. . Photoelectric and some synchronization equipment may be used for speed measurement. Many of these processes, such as process control, mechanical control, and transportation control, fall into this category.
Practicality The new brushless motor is closely linked with the development of electronics, microelectronics, digital technology, automation technology, and materials science. It is not limited to the field of AC and DC, but also relates to the field of energy conversion and signal sensing in electric and power generation. There are many new types of brushless motors in the field of motors, but brushless motors with excellent performance are not widely used due to price constraints. The following are the major new brushless motors for exploration and research.
