  1. 11. Sensorless Control of Brushless DC Motor in Hydraulic Application

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Martin Djup; Elias Allar; [2015]
    Keywords : Technology and Engineering;

    Abstract : In this master thesis we have studied the possibilities of implementing and controlling the speed of a brushless DC motor in an hydraulic application developed by BorgWarner TorqTransfer Systems AB. The hydraulic application is a coupling that give vehicles intelligent all-wheel drive. READ MORE

    Abstract : This Bachelor thesis is a part of a bachelor project which includes building, programming and controlling a 3DOF tandem helicopter. This particular report deals with the propulsion units, i.e. the motors and propellers of the helicopter. READ MORE

  4. 13. Energy efficient control of a low voltage motor to extend battery life

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Johan Malgerud; Daniel Skarp; [2014]
    Keywords : ;

    Abstract : Intresset för elektromekaniska lås ökar, på grund av dess många fördelar jämfört med de rent mekaniska låsen. Fördelar med elektromekaniska lås är, tillgång till online tillträdes hantering och billigare nycklar. READ MORE

  5. 14. BLCD ROV thruster design : Brushless DC motor thruster design for use on a remote operated underwater vehicle

    University essay from Uppsala universitet/Elektricitetslära

    Author : Emil Eriksson; [2014]
    Keywords : ;

    Abstract : The goal of this project is to design and simulate the electromagnetic circuit of a brushless dc motor meant to be used in a remote operated underwater vehicle. The final product is a drawing, see appendix A & B, of the design and the most relevant parameters are: R = 0.94 ohm and L =1.18mH per phase; at 250 rpm the motor produces 478. READ MORE

  6. 15. Analogue versus digital solution for motor control

    University essay from JTH, Data- och elektroteknik

    Author : Andreas Johansson; Max Stigborg; [2013]
    Keywords : Sensorless motor control; BLDC motor; BEMF; Zero-crossing; InstaSPIN;

    Abstract : Saab has an analogue solution which is used to drive small motors in aircrafts. The motor is a brushless DC-motor and uses a resolver and hall sensors to control it. READ MORE
