1. 1. Design and Evaluation of a Compact 15 kW PM Integral Motor

   Författare :Peter Thelin; KTH; []
   Nyckelord :integral motor; integrated motor drive; PM motor; PMSM; compact motor; filter coil; airgap flux density; axial leakage;

   Sammanfattning : This thesis deals with the integral motor of tomorrow, and particularly with a variable speed, sensorless permanent magnet synchronous motor with an integrated converter. The rated power is 15 kW at 1500 r/min. The outer dimensions are approximately the same as for the equivalent standard induction motor.Control strategies for pumps and fans, i. LÄS MER

3. 2. Integrated Motor Drives and Battery Chargers for Electric or Plug-in Hybrid Electric Vehicles

   Författare :Saeid Haghbin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum torque per Ampere strategy.; integrated motor drive and battery chargers; field-oriented control; battery charger; isolated and non-isolated integrated charges; Plug-in vehicles; split-phase PM motor;

   Sammanfattning : Plug-in vehicles, electric vehicles or plug-in hybrid electric vehicles, use grid power to charge the battery. The components in the traction circuit, like the electric motor and the inverter, are not used during the battery charging, so there is a possibility to use them in the charger circuit to reduce the size, weight and price of the on-board charger; that is called an integrated motor drive and battery charger or simply an integrated charger which can be galvanically isolated or non-isolated from the utility grid.

4. 3. Integrated Compact Drives for Electric and Hybrid Electric Vehicles

   Författare :Lebing Jin; Hans-Peter Nee; Staffan Norrga; Oskar Wallmark; Robert Pilawa-Podgurski; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed control; electric vehicle; energy storage capability; integrated motor drive; modular converter; modulation; power losses; stacked polyphase bridges converter; switching frequency; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : To develop more competitive solutions, one of the trends in the development of drive systems for electric and hybrid electric vehicles (EVs/HEVs) is to integrate the power electronic converter and the electric motor. This thesis aims to investigate the performance and the operation of modular converters in integrated motor drive systems for EVs/HEVs. LÄS MER

5. 4. On design methods for mechatronics : servo motor and gearhead

   Författare :Fredrik Roos; Jan Wikander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; mechatronics design methodology; servo systems; electric motors; gears; auxiliary systems; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : The number of electric powered sub-systems in road-vehicles is increasing fast. This development is primarily driven by the new and improved functionality that can be implemented with electro-mechanical sub-systems, but it is also necessary for the transition to electric and hybrid-electric drive trains.

7. 5. Integrated In-Wheel Motors for Low Power Traction Application

   Författare :Prakashraj Kasinathan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric golf cart; integral-slot; force density; flux-linkage; traction motors; forklift trucks; direct-drive; electric wheelchairs power wheelchairs; low speed machines; fractional-slot;

   Sammanfattning : This thesis is primarily concerned with the practical limits, imposed by magnetic saturation and thermal considerations, of the force density in low-speed permanent-magnet electric machines. The practical force density values obtainable in integral- and fractional-slot machines are determined. LÄS MER
