Tiivistelmä
Traction motor design significantly differs from industrial
machine design. The starting point is the load cycle
instead of the steady-state rated operation point. The speed of
the motor varies from zero to very high speeds. At low speeds,
heavy overloading is used for starting, and the field-weakening
region also plays an important role. Finding a suitable fieldweakening
point is one of the important design targets. At the
lowest speeds, a high torque output is desired, and all current
reserves of the supplying converter unit are used to achieve the
torque. In this paper, a 110-kW 2.5-p.u. starting torque and a
maximum 2.5-p.u. speed permanent-magnet traction motor will
be studied. The field-weakening point is altered by varying the
number of winding turns of machine. One design is selected for
prototyping. Theoretical results are verified by measurements.
