Energy Saving Permanent Magnet AC motor For Water Pump
What Is The Permanent Magnet Synchronous Motor?
1. Easy for replacement
The same installation size with asynchronous motor.
Due to the same motor seat number with same asynchronous motor(output<315kW), it can be easily changed.
Note) Some type of motors are longer than asynchronous motor. Details refer to outer dimension drawing.
2. High Power Factor
To reduce the capacity of power receiving equipment.
There is no doubt of high efficiency. Compared with asynchronous motor and standard type synchronous motor, it can reduce the current volume of equipment due to high power factor.
3.Speed control as per height
It is PG vector control.
Suitable for printer, punch compactor.
4. High efficiency & Energy Saving
Motor efficiency is equal to IE4 (Ultra high efficiency: above GB1 grade)
Note: IE4 is a efficiency grade specified in IEC 60034-30.
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.
Application:
It can be used in general industrial equipment, cooling towers, bag filters, papermaking machinery, textile machinery, transmission tools, pumps, extruders, air compressors, fans, etc. It can basically replace induction motors and DC motors in various applications.
Surface-mounted PMSM
In this construction, the magnet is mounted on the surface of the rotor. It is suited for high-speed applications, as it is not robust. It provides a uniform air gap because the permeability of the permanent magnet and the air gap is the same. No reluctance torque, high dynamic performance, and suitable for high-speed devices like robotics and tool drives.
Buried PMSM or Interior PMSM
In this type of construction, the permanent magnet is embedded into the rotor as shown in the figure below. It is suitable for high-speed applications and gets robust. Reluctance torque is due to the saliency of the motor.
