Widely Used IPM Permanent Magnet Synchronous Motor For Fan Pump
What Is The Permanent Magnet Synchronous Motor?
The PERMANENT MAGNET SYNCHRONOUS MOTOR is mainly composed of the stator, rotor, chassis, front-rear cover, bearings, etc. The structure of the stator is basically the same as that of ordinary asynchronous motors, and the main difference between the permanent magnet synchronous motor and other kinds of motors is its rotor.
The permanent magnet material with pre-magnetized (magnetic charged) magnetic on the surface or inside the permanent magnet of the motor, provides the necessary air gap magnetic field for the motor. This rotor structure can effectively reduce the motor volume, reduce loss and improve efficiency.
Analysis of the principle of the technical advantages of permanent magnet motor
The principle of a permanent magnet synchronous motor is as follows: In the motor's stator winding into the three-phase current, after the pass-in current, it will form a rotating magnetic field for the motor's stator winding. Because the rotor is installed with the permanent magnet, the permanent magnet's magnetic pole is fixed, according to the principle of magnetic poles of the same phase attracting different repulsion, the rotating magnetic field generated in the stator will drive the rotor to rotate, The rotation speed of the rotor is equal to the speed of the rotating pole produced in the stator.
Due to the use of permanent magnets to provide magnetic fields, the rotor process is mature, reliable, and flexible in size, and the design capacity can be as small as tens of watts, up to megawatts. At the same time, by increasing or decreasing the number of pairs of rotor permanent magnets, it is easier to change the number of poles of the motor, which makes the speed range of permanent magnet synchronous motors wider. With multi-pole permanent magnet rotors, the rated speed can be as low as a single digit, which is difficult to achieve by ordinary asynchronous motors.
Especially in the low-speed high-power application environment, the permanent magnet synchronous motor can be directly driven by a multi-pole design at low speed, compared with an ordinary motor plus reducer, the advantages of a permanent magnet synchronous motor can be highlighted.
Permanent Magnet Motors vs Induction Motors
1. The motor is small in size and light in weight
In recent years, with the continuous application of high-performance permanent magnet materials, the power density of permanent magnet synchronous motors has been greatly improved. The output torque of permanent magnet synchronous motors under the same volume is about 1.7 times that of induction motors.
2. Wide speed range
The permanent magnet synchronous motor based on the special structure design can adopt the maximum torque/current control strategy during constant torque operation and adopts the field weakening control strategy during constant power operation, which can obtain good speed regulation operation characteristics, and successfully achieve over 5 times the field weakening speed range.
3. Small moment of inertia, high acceleration can be obtained, and good dynamic performance
4. Large overload capacity
The rotor of a permanent magnet synchronous motor has no slippage. When rigid processing is carried out, there will be no surface effect processing abnormality caused by speed fluctuation.
Applications of Permanent Magnet Synchronous Motor
Permanent magnet synchronous motors have the advantages of simple structure, small size, high efficiency, and high power factor. It has been widely used in the metallurgical industry (ironmaking plant and sintering plant, etc.), ceramic industry (ball mill), rubber industry (internal mixer), petroleum industry (pumping unit), textile industry (double twist machine, spinning frame) and other industries in the medium and low voltage motor.
Permanent magnet synchronous motors can be combined with frequency converters to form the best open-loop step-less speed control system, which has been widely used for speed control transmission equipment in petrochemical, chemical fiber, textile, machinery, electronics, glass, rubber, packaging, printing, paper making, printing and dyeing, metallurgy and other industries.
Why choose permanent magnet ac motors?
Permanent magnet AC (PMAC) motors offer several advantages over other types of motors, including:
High Efficiency: PMAC motors are highly efficient due to the absence of rotor copper losses and reduced winding losses. They can achieve efficiencies of up to 97%, resulting in significant energy savings.
High Power Density: PMAC motors have a higher power density compared to other motor types, which means they can produce more power per unit of size and weight. This makes them ideal for applications where space is limited.
High Torque Density: PMAC motors have a high torque density, which means they can produce more torque per unit of size and weight. This makes them ideal for applications where high torque is required.
Reduced Maintenance: Since PMAC motors have no brushes, they require less maintenance and have a longer lifespan than other motor types.
Improved Control: PMAC motors have better speed and torque control compared to other motor types, making them ideal for applications where precise control is required.
What are the most appropriate applications?
PMACs will save energy in all motor applications due to their superior efficiency. The best applications are motors located in refrigerated spaces, due to the added benefits of reduced refrigeration load. Note that PMAC motors require variable frequency drives (VFDs) that are specially made.
What are the savings?
PMAC motors have 15-20% fewer energy losses than a standard NEMA Premium efficiency induction motor. Replacing just a two-horsepower induction motor with a PMAC motor in a large cooler would result in annual energy savings of about 400 kWh between energy and refrigeration savings. The savings will increase with motor size. Savings can be larger if the motor regularly operates at lower loads as PMACs are more efficient at these conditions than other motors.
What are the non-energy benefits?
The lower operating temp of PMAC motors reduces maintenance needs and increases equipment life. Their synchronous operation allows for improved speed control over induction motors. Finally, they operate at higher power factors.
Environmentally Friendly: PMAC motors are more environmentally friendly than other motor types since they use rare earth metals, which are easier to recycle and produce less waste compared to other motor types.
Overall, the advantages of PMAC motors make them an excellent choice for a wide range of applications, including electric vehicles, industrial machinery, and renewable energy systems.
