Used technology
This
electric machine
is a
Syncronous Reluctance assisted Permanent Magnet (SRPM) machine.
This technology has several benets compared to standard permanent magnet (PM) technology
and traditional induction machine (IM) technology. The SRPM technology combines the benets
of PM and Syncronous Reluctance technology, having increased torque capability over wide speed
range and ability to produce torque to higher speeds. The machine efficiency at lower speeds is
also good.
The supply current to the stator windings create rotating magnetic eld, which in turn rotates the
rotor containing permanent magnets. In the syncronous permanent magnet machine, the rotation
of the rotor (shaft) is syncronized with the frequency of the power supply current. The reluctance
technology maximizes the pull-out torque of the machine.
The permanent magnets of
the rotor are of salient-pole design, having embedded permanent
magnets in the rotor structure. This structure makes the machine mechanically more stable and
capable of higher speed operations. See Figure below illustrating the magnet topology of the
electric machine. The gure shows the principle only, and is not an exact illustration of the
structure.
