In a speed control system of a synchronous motor, a pulse modulated signal containing a signal representing rotational angle of the motor is formed to control the speed. The pulse modulated signal is passed through a synchronous rectifier to obtain currents supplied to stator windings of the motor...
Using this simple formula: Ns = (120xf) / p , we can calculate the synchronous speed of any synchronous motor.Let’s look at this formula in more detail. Table of Contents What is Ns=(120xf)/p all about? Why do we require speed control of synchronous motors? What parameters can we...
The aim of this thesis is to analyze discrete-time models and current control of synchronous motors with a magnetically anisotropic rotor structure, such as interior permanent-magnet synchronous motors (IPMSMs) and synchronous reluctance motors (SyRMs). Current regulators in most modern electrical driv...
In a one-way direction control for synchronous motors that are capable of starting in either direction when energized, the motor shaft is drivingly connected to a rotatable driving element that has a circumferential smooth surface through which and one end of said element opens a notch at one ...
This paper deals with the study and development of new control solutions of permanent-magnet synchronous motor (PMSM) drives specifically aimed to operate under sensorless vector control even during fault conditions. The phase imbalance produced by an open-phase fault leads to the failure of several...

Permanent magnet synchronous (PMS) motors stand at the forefront of electric motor development due to their energy saving capabilities and performance potential. Expanding environmental crises and increasing electricity prices on the one hand, and emerging motor drive applications like electric and hybrid ...
专利附图：摘要：Control of Linear Synchronous Motors involves a number of low level issues of motor control—such as sensing precise position, controlling current in stator windings,and obeying commands from high level controllers—and high level vehicle control—such as stopping and starting, ...
