A New Single-Phase Line-Start Permanent Magnet Synchronous Motor
22. april 2008, Maribor, TECES
With the newly developed solution
TECES supplements the existing knowledge in the research and development field of new concepts of electric machines, which enables potential motor manufacturers and suppliers the marketing of products on markets, which demand highly-efficient electro-motors for single-phase supply systems.
TECES’ and UM-FERI’s joint development of
energy high-efficient electric drive systems presents the
newly developed single-phase line-start permanent magnet synchronous motor, which
unites advantages of the single-phase induction motor and the permanent magnet synchronous motor (for more information click here).
The newly developed
single-phase line-start permanent magnet synchronous motor
is capable of line-starting from a single-phase supply by the help of a starting-capacitor in the auxiliary phase (i.e. it is able to start from zero rotor speed when fed from a single-phase constant amplitude and constant frequency voltage source).
The capacitor-run single-phase line-start permanent magnet synchronous motor exhibits higher efficiency and power factor values (
Figure 1) compared to an induction motor with equal dimensions and rated data (220V/50Hz 750W 1400rpm). Moreover, the new motor exhibits substantially
higher power factor values than the induction motor if the capacitor in the auxiliary phase is used only for line-starting (
Figure 2).
Consequently, the new single-phase line-start permanent magnet synchronous motor
generates less heat. The average main phase winding temperature in thermal equilibrium is approximately 15°C lower for the capacitor-run motor and 29°C lower for the capacitor-start motor when compared to the induction motor, respectively.
