High Efficiency And Energy Saving: Compared with the traditional asynchronous motor drive system, the motor efficiency under permanent magnet synchronous inverter drive is higher. Permanent magnet synchronous motors have no rotor copper consumption and can maintain high efficiency at light loads and near rated loads. The precise control of the frequency converter further optimizes the motor's operating state, enabling the motor to minimize energy loss and achieve energy saving under various working conditions.


High Power Factor: Permanent magnet synchronous frequency converter can make the motor maintain a high power factor during operation, which means that the motor has a small demand for reactive power from the grid, reducing the reactive power loss of the grid and the current capacity requirement of the power supply line. This not only reduces the cost of electricity for enterprises, but also reduces the burden on the power grid, which has a positive impact on the stable operation of the power system.


Accurate Speed And Torque Control: Permanent magnet synchronous inverter can realize high-precision control of motor speed and torque. Through advanced control algorithms, such as vector control and direct torque control, the motor output can be adjusted accurately in an instant to meet the requirements of complex production processes.


Flexible Speed Regulation And Load Matching: Permanent magnet synchronous inverter can realize flexible speed regulation function and precisely adjust the motor speed according to the actual load demand, so as to achieve the best matching with the load. This is very useful in many industrial applications, such as fans, pumps and other equipment, by changing the motor speed to control the flow or pressure, rather than through the adjustment of valves or baffles to control, thus greatly reducing energy loss.


Energy feedback and Regeneration: Some permanent magnet synchronous frequency converter with energy feedback function. When the motor is in the deceleration or braking state (such as elevator down, crane lowering heavy loads, etc.), the motor from the electric state into a power generation state, the frequency converter can be generated by the motor regeneration of electric energy back to the grid for other equipment use or storage. This mechanism not only reduces the waste of energy, but also improves the power quality of the grid and increases the efficiency of energy utilization.


Small Size And Light Weight: Due to the compact structure of the permanent magnet synchronous motor itself, coupled with the optimization of the design of the frequency converter with it, the entire drive system compared to the traditional asynchronous motor drive system is smaller in size and lighter in weight. This is very favorable for equipment installation environment with limited space.

 

Types of Permanent Magnet Synchronous Frequency Converter

 

 

General-purpose Frequency Converter

Applicable to a variety of motor types, including permanent magnet synchronous motor. These inverters have the advantages of wide speed regulation range, fast dynamic response and good stability. They usually use space vector pulse width modulation technology, which can effectively reduce the noise and vibration of motor operation and improve motor efficiency. General-purpose inverter also has rich protection functions, such as over-current, over-voltage, under-voltage, overload, etc., to ensure the safe and reliable operation of the motor.

 

Specialized Inverter

It is specially designed for permanent magnet synchronous motor, and fully considers the characteristics of permanent magnet synchronous motor, such as high magnetic field strength, low rotor inertia and so on. Therefore, the control strategy and protection functions are optimized to achieve higher control accuracy and dynamic performance. This type of inverter is especially suitable for occasions with high requirements on motor performance, such as precision machinery, cnc machine tools and so on.

 

Vector Control Inverter

Vector control technology is used to precisely control the magnetic field and torque of the motor. This control method can make the permanent magnet synchronous motor maintain a large torque output at low speeds and improve the starting and braking performance of the motor. At the same time, vector control inverter also has a strong anti-interference ability, and can operate stably in harsh industrial environments. Therefore, vector control inverters are widely used in heavy industries such as electric power, metallurgy and chemical industry.

Q: What are the characteristics of permanent magnet synchronous generator?

A: Compared with the traditional electric excitation generator, the permanent magnet synchronous generator(PMSG) has the characteristics of high efficiency, high power density, stable and controllable output voltage, and good heat dissipation performance, and is especially suitable for automotive applications.

Q: What is the difference between permanent magnet synchronous motor?

A: Difference between usually refers to comparisons. You want to point out distinguished differences. Below are a few examples: The difference between you and me is that I'm outgoing and you are reserved.

Q: What is the difference between a synchronous generator and a permanent magnet synchronous generator?

A: Synchronous generators can be started by supplying the rotor field excitation from a battery. Permanent magnet synchronous generators require no rotor field excitation. The construction of asynchronous generators is less complicated than the construction of synchronous generators.

Q: What is the purpose of using a permanent magnet in synchronous motors?

A: The working of PMSM depends on the rotating magnetic field of the stator and the constant magnetic field of the rotor. The permanent magnets are used as the rotor to create constant magnetic flux, operates and locks at synchronous speed.

Q: What is the speed of the permanent magnet synchronous motor?

A: The speed of a permanent magnet synchronous motor is determined by n=120fp, where f is frequency, n is speed in rpm and p is number of poles. p is fixed in a motor so changing the frequency changes the speed. If I have a 4 pole motor and I set the frequency to 50Hz I get 1500rpm.

Q: How do you control a permanent magnet synchronous motor?

A: We can use an absolute position sensor (e.g., resolver) or a relative position sensor (e.g., encoder) and process called alignment. During the alignment, the rotor is aligned with phase A and we know that phase A is aligned with the direct (flux producing) axis.

Q: What is the vector control of a permanent magnet synchronous motor?

A: The concept of vector control is applied to PMSM to obtain linear dynamics similar to that of a DC motor. The linearized model consists of two control loops namely, current loop and speed loop. The objective of the control scheme is to achieve very fast response.

Q: WIs permanent magnet synchronous motor self starting?

A: Unlike induction motors, which are self-starting due to the rotating magnetic field produced by the stator, synchronous motors require external means to start.
