Description: This paper presents the sensorless direct torque
control (DTC) technique for five-phase interior permanent
magnet (IPM) motors. By using the introduced technique fast
torque response with low ripple in the stator flux and torque of
the five-phase interior permanent magnet motor can be achieved.
Having thirty-two space voltage vectors provides great flexibility
in selecting the inverter switching states. Therefore, the stator
flux and torque can be more precisely adjusted. Position
information and speed are being estimated based on the position
of the stator flux linkages. The mathematical model of the fivephase
interior permanent magnet motor is first derived. Later,
the speed sensorless direct torque control method of the fivephase
IPM is introduced. A five phase interior permanent
magnet motor and five leg IGBT based inverter were designed
and fabricated in the laboratory. The control method is
implemented on a TMS320C32 digital signal processor board.
