TIMEPERIOD: LANGUAGE:Swedish EXAMINER L Lindqvist Univ adj PREREQUISITES Recommended previous knowledge: Circuits Analysis Automatic Control COURSE AIM The purpose of course it is to give the students a survey over the area of DC-motors and steppingmotors as systemcomponents and give knowledge so they can understand information in specialist literature, catalogues, and data-sheets. After the course the students can make well-founded choice among different alternativ for example then to choice motors in controlequipment. specialist literature, catalogues, and data-sheets. After the course the students can make well-founded choice among different alternativ for example then to choice motors in controlequipment. CONTENTS Fundamentel theory: Magnetic flux - and flux density. Force on a conductor in a magnetic field. Electromotive force. DC-motors: Permanent-magnet DC- motors and brushless DC- motors. Transfer functions. Response to a step voltage. Damping. Electrical analogy for a motor with a load. Torsional resonance. Mechanical and electrical time constants. Power dissipation and efficiency. Intermittent operation. Thermal model and thermal analysis. Steppingmotors: Principles of variable reluctance -, permanent magnet - , hybrid - and linear stepping motors. Transfer functions. Response to a step voltage. Resonances and instabilities. Mechanical dampers. Drive system and circuitry: Transistors bridge circuits. Amplifiers. Motor drivers. Logic sequencer. Monolithic motor drivers. Microprocessor based motor drivers. Motor controls: Example of speed, positions torque control. TEACHING The teaching concist of lessons and laboratory lessons. Laboratory lessons have elements of simulating with computers. EXAMINATION An examination with differentiated grade. Marking papers as alternative B in "Regler för tentamen".
