A linear synchronous motor consists of a moving part - an armature and a magnetic road - a stator.
The anchor contains a toothed magnetic circuit, with a three-phase winding laid in grooves, filled with a heat-conducting compound.
The stator consists of alternating polarity rare earth magnets glued to a steel plate.
For normal engine operation, the air gap between the armature and the stator should be about 1 mm.
The force is transmitted directly through the air gap, i.e. no mechanical transmission.
This provides high precision engine parameters, acceleration and speed, reliability
Linear synchronous motors develop a uniform linear force due to the interaction of the magnetic field of the armature with the permanent magnets of the stator.
A distinctive feature of a linear synchronous motor over other linear systems is the lack of mechanical transmission (direct drive).
Position sensors with a period of 20, 40 μm or 2 mm and an output of 1 Vss or RS422 are used
