This interacts with the stator RMF poles, which cause rotational output. These motors must be controlled with a variable frequency drive (VFD), as the only way to alter their speed and torque is by changing the stator AC … great white paper landing pagesWebThe magnetic field for a synchronous machine may be provided by using permanent magnets made of neodymium-boron-iron, samarium-cobalt, or ferrite on the rotor. In some motors, these magnets are mounted with adhesive on the surface of the rotor core such that the magnetic field is radially directed across the air gap. In other designs, the magnets are … florida state board of nursing schoolsA PM motor is an ac motor that uses magnets imbedded into or attached to the surface of the motor’s rotor. The magnets are used to generate a constant motor flux instead of requiring the stator field to generate one by linking to the rotor, as is the case with an induction motor. A fourth motor known as a line-start … See more An ac induction machine (IM) also is commonly referred to as an ac motor. A rotating field is generated by the stator winding. The rotating field induces a current in the rotor bars. The current generation requires a … See more To understand the operation of PM motors, it is important to first understand the concepts of magnetic flux, flux linkage, and magnetic flux. Flux: The flow of current through a conductor creates a magnetic field. Flux … See more An electric machine’s torque can be broken down into two components: magnetic torque and reluctance torque.
