Elektrische Klein-, Servo- und Fahrzeugantriebe

This course is offered in German.

• Introduction, magnet materials.
• Permanent magnet DC motors: designs (drum-type, disc-type and bell-shaped rotors), applications, magnet materials, performance, speed control, electronic circuits for supply.
• Electronic motors: Torque generation with block current, designs with different numbers of phases, drum and disk rotors, motors with slotted stator or air gap windings, hybrid motors, switched reluctance motors; operating performance.
• Permanent magnet synchronous motors: Special features, magnet topologies, operating performance.
• Basics of servo drives: DC, induction and synchronous servo motors and their description using systems technical block diagrams.
• Automotive drives: claw-pole generators (bicycle, car), traction motors (types, special features, energy efficiency, performance in the constant power range), assisting drives.
• Important system characteristics: Rotor position encoders (incremental and absolute encoders, magnetic or optical operating methods, resolvers), generation and avoidance of shaft voltages and bearing currents, HF voltage effects on the winding, noise assessment.
