220v 380v 50hz Neodymium Permanent Magnet Motor IC411 Cooling

The characteristics and advantages of permanent magnet motors:

Motor from the source of excitation can be divided into two categories: permanent magnet motor, and electric excitation motor. A permanent magnet motor is an electric motor that produces an excitation magnetic field from a permanent magnet. The most widely used three-phase asynchronous motors in industry and civil use, such as Y-Series, Y2-Series, YE2-Series, YX3 Series, Series YB, series YB2 series, etc. all belong to electric excitation motors. ENNENG Motor products are ultra-efficient permanent magnet synchronous motors.

Compared with traditional electric excitation motors, permanent magnet motors, especially rare earth permanent magnet motors, have the advantages of simple structure, reliable operation, small size, lightweight, small loss and high efficiency, and flexible and diverse shape and size of the motor. The application is extremely wide, covering almost all areas of aerospace, national defense, industrial and agricultural production, and daily life.

The permanent magnet synchronous motor has the following characteristics:

• Rated efficiency is 2% to 5% higher than normal asynchronous motors;
• The efficiency rises rapidly with the increase of the load. When the load changes within the range of 25% to 120%, it maintains high efficiency. The high-efficiency operating range is much higher than that of ordinary asynchronous motors. Light-load, variable-load, and full-load all have significant energy-saving effects;
• Power factors up to 0.95 and above, no reactive compensation required;
• The power factor is greatly improved. Compared with asynchronous motors, the running current is reduced by more than 10%. Due to the decrease in operating current and system losses, energy-saving effects of about 1% can be achieved.
• Low-temperature rise, high power density: 20K lower than three-phase asynchronous motor temperature rise, design temperature rise is the same and can be made into a smaller volume, saving more effective materials;
• High starting torque and high overload capacity: according to requirements, it can be designed with high starting torque (3-5 times) and high overload capacity;
• The variable frequency speed control system is used, which is better in dynamic response and better than that of asynchronous motors.
• The installation dimensions are the same as the asynchronous motors currently widely used, and the design and selection are very convenient.
• Due to the increase in power factor, the visual power of the power supply system transformer is greatly reduced, which improves the power supply capacity of the transformer, and can also greatly reduce the cost of the system cable (new project);
• When the new project is built, all the drive systems use permanent magnet synchronous motors, the project investment is basically the same as the use of asynchronous motors, and the project can continue to obtain energy-saving benefits after the project is put into operation;

In the general industrial sector, the replacement of low-voltage(380/660/1140V) high-efficiency asynchronous motors, system saves 5% to 30% energy, and the high-voltage(6kV/10kV) high-efficiency asynchronous motors, the system saves 2% to10%.

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.

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.

Application:

Permanent magnet synchronous motors can be combined with frequency converters to form the best open-loop steppless 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 you should choose an IPM motor instead of an SPM?

1. High torque is achieved by using reluctance torque in addition to magnetic torque.

2. IPM motors consume up to 30% less power compared to conventional electric motors.

3. Mechanical safety is improved as, unlike in an SPM, the magnet will not detach due to centrifugal force.

4. It can respond to high-speed motor rotation by controlling the two types of torque using vector control.
