Energy Saving Maintenance-Free Permanent Magnet Ac Motor For Air Blower
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.
>The working principle of Permanent Magnet Motor
The working principle of pmsm motor is the same as that of the synchronous motor. PMSMs are widely used now, and like induction motors, they have commonly used AC motors. >> The characteristics are: during steady-state operation, there is a constant relationship between the rotor speed and the grid frequency n=ns=60f/p, and ns is called synchronous speed. >> If the frequency of the power grid is constant, the speed of the synchronous motor is constant at a steady state regardless of the size of the load. >> Operating as a generator is the most important operating mode of a synchronous motor, and operating as a motor is another important operating mode of a synchronous motor. >> The power factor of the synchronous motor can be adjusted. In the occasions where speed regulation is not required, the application of a large synchronous motor can improve the operating efficiency. >> In recent years, small synchronous motors have been used in variable frequency asynchronous motors, also known as induction motors, which are AC motor that generates electromagnetic torque through the interaction of the air gap rotating magnetic field and the induced current of the rotor winding, thereby realizing the conversion of electromechanical energy into mechanical energy.
> Detailed pictures Benefits of PMSM motors: Driving lower speeds at higher efficiency than an induction motor might delete the requirement of a speed-reduction transmission, taking the complexity out of the mechanical arrangement.

Permanent magnet AC (PMAC) motors have a wide range of applications including:
Industrial Machinery: PMAC motors are used in a variety of industrial machinery applications, such as pumps, compressors, fans, and machine tools. They offer high efficiency, high power density, and precise control, making them ideal for these applications.
Robotics: PMAC motors are used in robotics and automation applications, where they offer high torque density, precise control, and high efficiency. They are often used in robotic arms, grippers, and other motion control systems.
HVAC Systems: PMAC motors are used in heating, ventilation, and air conditioning (HVAC) systems, where they offer high efficiency, precise control, and low noise levels. They are often used in fans and pumps in these systems.
Permanent magnet synchronous motors with internal magnets: Maximum energy efficiency
The permanent magnet synchronous motor with internal magnets (IPMSM) is the ideal motor for traction applications where the maximum torque does not occur at maximum speed. This type of motor is used in applications that require high dynamics and overload capacity. And it is also the perfect choice if you want to operate fans or pumps in the IE4 and IE5 range. The high purchase costs are usually recouped through energy savings over the run time, provided that you operate it with the right variable frequency drive.
Our motor-mounted variable frequency drives use an integrated control strategy based on MTPA (Maximum Torque per Ampere). This allows you to operate your permanent magnet synchronous motors with maximum energy efficiency. The overload of 200 %, the excellent starting torque, and the extended speed control range also allow you to fully exploit the motor rating. For fast recovery of costs and the most efficient control processes.
IPM (Interior Permanent Magnet) Motor Features:
High torque and high efficiency
Energy- saving operation
High- speed rotation
Safety
Permanent magnet synchronous motors with external magnets for classic servo applications Permanent magnet synchronous motors with external magnets (SPMSM) are ideal motors when you need high overloads and rapid acceleration, for example in classic servo applications. The elongated design also results in low mass inertia and can be optimally installed. However, one disadvantage of the system consisting of SPMSM and variable frequency drive is the costs associated with it, as expensive plug technology and high-quality encoders are often used.
Renewable Energy Systems: PMAC motors are used in renewable energy systems, such as wind turbines and solar trackers, where they offer high efficiency, high power density, and precise control. They are often used in the generators and tracking systems in these systems.
Medical Equipment: PMAC motors are used in medical equipment, such as MRI machines, where they offer high torque density, precise control, and low noise levels. They are often used in the motors that drive the moving parts in these machines.
Advantages
Provides higher efficiency at high speeds Available in small sizes in different packages Maintenance and installation are very easy than with an induction motor Capable of maintaining full torque at low speeds High efficiency and reliability Gives smooth torque and dynamic performance
Disadvantages The disadvantages of permanent magnet synchronous motors are: These types of motors are very expensive when compared to induction motors Somehow difficult to start up because they are not self-starting motors.
I. Maintenance >>
1. Please carry out regular maintenance of the bearing strictly in accordance with the bearing lubrication indication plate. The motor should be refilled with grease immediately after running for about 2000 hours, and the grease brand must be carefully identified before refilling. When the bearing is found to be overheated or the grease is degraded during operation, it should be replaced in time. The old grease should be removed when replacing, and the bearing and the inner and outer cover oil chambers of the bearing should be cleaned with gasoline, and then clean grease of the same brand should be added. Motor with a speed of 3000rpm and above, the amount of refueling: the bearing cavity is filled, the amount of grease added to the oil chamber of the bearing inner cover accounts for 1/2 of the oil chamber, the remaining speed motor refueling amount: the bearing inner cavity is filled, and the bearing inner cover oil chamber is filled The amount of grease occupies 2/3 of the oil chamber. >>
2. When replacing the bearing, a special bearing disassembly tool must be used to pull the bearing from the motor shaft, and the disassembly force must not be directly applied to the motor shaft. When installing a new bearing, the hot sleeve method should be used to install the bearing. After the bearing is heated to 90°C, the bearing sleeve should be placed on the bearing position on the shaft. >>II. Storage>>The motor should be stored in a ventilated and dry place without corrosive gas. >>III. Disclaimer>>The company is not responsible for maintenance and compensation for motor failures that occur in the following situations. >>
1. The long-term severe overload operation of the motor causes the winding to become heated and burned. >>
2. The product is not installed correctly, such as severely knocking on the motor spindle and the flange surface of the machine cover to cause deformation of the parts. >>
3. The user does not use and store the motor correctly according to the provisions of this manual, and the failure and loss are caused by human factors. > |
