BADANIA SILNIKA BLDC PRZEZNACZONEGO DO LOTNICZEGO NAPĘDU HYBRYDOWEGO

RESEARCH OF BLDC MOTOR DESIGNED FOR AIRCRAFT HYBRID DRIVE

Abstract: The concept of aircraft hybrid drive (engine - electric motor) was discussed in the papcr. Basic laboratory research results of BLDC motor like dependence on electromagnetic torque and cogging torque vs rotor position were also included in the paper. Parameters needed for the proper performance of the BLDC motor in the aircraft hybrid drive were assessed.

BADANIA SYMULACYJNE SILNIKA SKOKOWEGO RELUKTANCYJNEGO

SIMULATION RESEARCH OF STEPPER RELUCTANCE MOTOR

Abstract: The paper shows the results of a simulation research of the three pliase reluctanee stepper motor. The mathematical model of the stepper motor was presented. The simulation model of drivc was accomplished in Matlab/Simulink system. The researches were realized for a full-step and half-step commutations method. The limit characteristics of the over speed condition for the conunutation method described above were deter-mined. Time courses of current, rotary speed and rotor position were presented and the conclusions were en-closed.

MOTORS FOR INTERMITTENT DUTY DRIVES

Abstract: Intermittent duty electrical drives are often encountered in military devices. Depending on the drive function, the motor may nin for one or several seconds. One possible choicc of motor for such a drive is dc series motor with mechanical commutator. These motors are very well suited to pulse (intermittent) duty. However, a major drawback is sparking occurring at large current overloads. Altematively. these drives may be equipped with BLDC (brushless dc) motors. characterised by high efficiency. high power density and torque overload capacity resulting in high operational dynamics.
