Control system with position sensor is susceptible to the severe environment such as high temperature, humidity and vibration, which reduce the stability of control system. Position sensorless control of permanent magnet linear synchronous motor need not position sensor so that it can use in abominable environment. According to three phases voltage and two phases current measured from motor, the position and speed of motors mover can be estimated directly based on extended Kalman filter algorithm which is a kind of recursive algorithm. So position sensorless close loop control of PMLSM can be realized.

Because of its high dynamic response speed and acceleration, high rigidity and positioning accuracy, the permanent magnet linear synchronous motor (PMLSM) is able to meet the requirements of high-speed precision CNC machine tools. However, its thermal problems have seriously hampered its development. This paper establishes a PMLSM temperature field model, designs a cooling structure, determines the boundary conditions of the finite element model and conducts computer simulation of the model. The result shows that the designed cooling structure can effectively alleviate the motors thermal problems.

The permanent magnet linear synchronous motor (PMLSM) has a good application prospect due to many significant advantages such as high speed, high precision, high thrust force density, simple structure, energy saving and reliable operation etc., so the research and development are of great importance. This paper mainly focuses on the key design points of a double-sided water-cooled PMLSM. According to the required thrust force, the design is given out including the basic structure parameters, winding connection methods and water cooling system. Based on the erected finite-element model, the performances such as back-EMF, thrust force, normal force, power factor and efficiency are predicted. By comparing with a single-sided PMLSM with the same specifications, it is proved that this double-sided PMLSM has lower thrust force ripple and higher thrust force density. Moreover, the net normal force of its mover is almost zero. Finally, the predicted back-EMF is verified by measurement.
