Neodymium-boron-iron permanent magnets are the most commonly used because they are readily available and reasonably priced. This kind of magnet is fixed to the rotor, which is normally housed inside the electric motor's stator. On the other hand, certain motor configurations include an external rotor, which leads to an inside-out design.
The rotor primarily comprises these powerful permanent magnets, which are selected for their high coercive force. On the other hand, the stator consists of an outer frame and core housing windings. In many cases, a design incorporating two- or three-phase windings is commonly adopted for the stator.
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.
Working Principle of PMSM
A synchronous motor works on the basis of the interaction between the constant magnetic field of the rotor and the spinning magnetic field of the stator. A revolving magnetic field is produced by a synchronous motor's stator, just like in a three-phase induction motor. Ampere's Law states that torque is produced by the synchronous alternating current from the stator windings and the rotor's magnetic field. This torque allows the rotor to rotate more easily.
A constant magnetic field is produced by permanent magnets on the rotor of permanent magnet synchronous motors (PMSM). The rotor's poles line up with the stator's revolving magnetic field when it rotates at the synchronous speed. As a result, when directly linked to a network of three-phase current, PMSMs are unable to self-start.
