reaches synchronous speed, at which point the magnetization direction of the rotor stays substantially constant. Such a motor operates with a very small angle between the flux induced by the stator windings and the magnetization flux of the rotor. This angle is typically a maximum of 38-42 ...
A complex magnetic field generating device, comprising a frame, a plurality of magnets capable of producing a magnetic field, wherein each of the plurality of magnets has a north pole and a south pole
FOC is a common form of vector control. It is a cascade control structure with an inner current and outer speed loop. The control loops placed in series represent feedback in a closed-loop system. However, a transformation of the controllable motor quantities, such as current and voltage, fr...
This paper proposes a novel constant power factor loop in the V/f control strategy with stabilization for a permanent magnet synchronous motor (PMSM). The advantage of such an algorithm is the independence of the machine parameters, which vary under diff
