PERFORMANCE OF ELECTRIC MEDIUM-SIZED VARIABLE-RPM ROTOR AND SHROUDED ROTOR

2022
Electric variable RPM rotors are increasingly being used for propulsion and control of unmanned air vehicles. As these vehicles scale to carry heavier payloads of 50 to 400 lbs (20 to 180 kgs) in the group 2 and 3 UAS category, there are concerns about their aerodynamic performance and handling quality degradation. Therefore, there is a need to develop

Twin rotor drive for an electric vehicle

IEE Proceedings B Electric Power Applications, 1993
An original electric machine is described which has a single stator and two rotors, each core being of a disc geometry, with the stator sandwiched between the two rotors. The rotors carry squirrel cage windings, and are mounted on individual, independent shafts driving two wheels of an electric vehicle. The torque generated by each rotor depends on the

Modal test of an electrical machine rotor

2010 12th International Conference on Optimization of Electrical and Electronic Equipment, 2010
The aim of this paper is to present an experimental procedure used to determine the fundamental natural frequency and the damping ratio of an electrical machine rotor. There are described both the experimental set-up and the damping ratio calculation, using classical methods of modal testing.

Balancing flexible rotors of large electrical machines

2010 Record of Conference Papers Industry Applications Society 57th Annual Petroleum and Chemical Industry Conference (PCIC), 2010
This paper describes how rotors of large electrical machines with bending modes within the speed range can be balanced. A method is described, that allows for high speed balancing in a safe environment (a balancing facility) and avoids correctional balancing in the complete machine setup.

Airgapless Electric Motors With an External Rotor

IEEE Transactions on Industrial Electronics, 2018
This paper proposes a new family of electric motors based on the concept of an airgapless device. In this type of device, the rotor is allowed to touch the stator at a contact point, which maximizes the internal flux and, therefore, the electromagnetic torque. A higher torque density motor is proposed in this paper due to a reduced reluctance caused by

Effects of Rotor Position Error on Longitudinal Vibration of Electric Wheel System in In-Wheel PMSM Driven Vehicle

IEEE/ASME transactions on mechatronics, 2018
The influence of a rotor position error on the longitudinal vibration of an electric wheel system is analyzed. To begin with, the influence of the rotor position error on the motor current and torque is deduced using coordinate transformation.
