Energy Efficient Rare Earth Permanent Magnet Synchronous Motor
Product Description
High-efficiency permanent magnet variable frequency synchronous motors must be used in conjunction with permanent magnet motor frequency converters. The rotor of the motors has a built-in permanent magnet structure, and the special design of different vertical and vertical axis magnetic circuits makes this series of motors have a certain salient pole torque. Therefore, the frequency converter needs to use the maximum torque/current ratio control mode to control the work, so that this series of motors have a higher power factor in the full speed range, a smaller operating current, and lower copper consumption.
The speed of the high-efficiency permanent magnet variable
frequency synchronous motor is synchronized with the stator
rotating magnetic field, there is no slip, and the slip power is
saved, so that the high-efficiency permanent magnet variable
frequency synchronous motor has high efficiency and energy saving
effect in the full speed range obvious.
The high-efficiency permanent magnet frequency conversion
synchronous motors are widely used in injection molding machines,
air compressors, pipe-making equipment, hydraulic machinery, food
machinery, cement pipe-making machines, plastic extruders, wire
drawing machines, and pharmaceutical equipment.
Our company is equipped with a dedicated control cabinet for this
series of products, which can be customized according to user
requirements.

Working of Permanent Magnet Synchronous Motor:
The working of the permanent magnet synchronous motor is very simple, fast, and effective when compared to conventional motors. 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, operate, and lock at synchronous speed. These types of motors are similar to brushless DC motors.
The phasor groups are formed by joining the windings of the stator with one another. These phasor groups are joined together to form different connections like a star, Delta, and double and single phases. To reduce harmonic voltages, the windings should be wound shortly with each other.
When the 3-phase AC supply is given to the stator, it creates a rotating magnetic field and the constant magnetic field is induced due to the permanent magnet of the rotor. This rotor operates in synchronism with the synchronous speed. The whole working of the PMSM depends on the air gap between the stator and rotor with no load.
If the air gap is large, then the windage losses of the motor will be reduced. The field poles created by the permanent magnet are salient. The permanent magnet synchronous motors are not self-starting motors. So, it is necessary to control the variable frequency of the stator electronically.
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.
Maintenance and repair of electric motors
1. The operating environment should always be kept dry, the surface of the motor should be kept clean, and the air inlet should not be obstructed by dust, fibers, etc.
2. When a protection alarm occurs, the cause of the failure should be found out, and the operation can only be put into operation after the failure is eliminated.
3. When the machine is stopped for inspection, the operation can only be carried out after the motor has completely stopped.
4. In order to ensure good lubrication of the motor during operation, the motor should run for about 4000 hours, that is, the grease should be supplemented or replaced (the closed bearing does not need to be replaced during the service life). When the bearing is found to be overheated or the grease has deteriorated during operation, The grease should be replaced in time. When replacing the grease, remove the old grease and clean the oil grooves of the bearings and bearing caps with gasoline. For motors with a speed of 1500r/min and below, refill the bearing grease type for medium and small motors bearing grease No. 2, and fill the inner and outer rings of the bearing About two-thirds of the gap between the bearings; the motor speed of 2500r/min and above is filled with bearing grease type HTHS, which fills about one-half of the gap between the inner and outer rings of the bearing.
5. When the life of the bearing is over, the vibration and noise of the motor will increase obviously. Check that the radial clearance of the bearing reaches the value in the table below, and the bearing should be replaced.
