Vibration Predicition using Relative Permeance of IPMSM
2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020Tooth-wound motors, such as interior permanent-magnet synchronous motors (IPMSMs), are commonly used for their convenience; however, they exhibit the disadvantages of cogging torque and electromagnetic vibrations. In this paper, a relative-permeance equation is proposed to help predict electromagnetic vibrations in the basic design of a tooth-wound ...

“Active Flux” DTFC-SVM Sensorless Control of IPMSM
IEEE Transactions on Energy Conversion, 2009This paper proposes an implementation of a motionsensorless control system in wide speed range based on "active flux" observer, and direct torque and flux control with space vector modulation (DTFC-SVM) for the interior permanent magnet synchronous motor (IPMSM), without signal injection.

Novel IPMSM drive for compact washing machine
INTELEC 2009 - 31st International Telecommunications Energy Conference, 2009This paper describes high-performance novel Interior Permanent Magnet Synchronous Motor (IPMSM) drive for compact washing machine. The motor has been designed to decrease size of the existing drives and create more compact washing machine. It utilizes inner rotor motor scheme in contrast to the conventional drives, which use outer rotor motor scheme ...

Torque-Sensorless Identification of IPMSM Torque Map
2021 IEEE Energy Conversion Congress and Exposition (ECCE), 2021This paper analyzes the torque equation of an interior permanent-magnet synchronous machine (IPMSM), including magnetic saturation, spatial harmonics, and the variation of the magnetic energy. Based on the analysis, a torque-sensorless method is proposed to identify an IPMSM’s torque map.

IPMSM with Rotor Using Two Different Cores
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019Interior permanent magnet synchronous motor (IPMSM) with the rotor using two different cores is proposed. Permalloy is used in part of the rotor. In this paper, the principle of motor performance is described. Permalloy operates same as a flux barrier when the motor drives at low speed and high torque, and it actively operates to short circuit the ...

IPMSM with ferrite magnets for high speed
2015 18th International Conference on Electrical Machines and Systems (ICEMS), 2015This paper describes an interior permanent magnet synchronous motor (IPMSM) employing ferrite magnets instead of rare earth magnets that can be driven at high speeds. Neodymium and dysprosium are raw materials of rare earth magnets used in IPMSM, and the prices of these materials rose until recently.

Highly Demagnetization Performance IPMSM Under Hot Environments
IEEE Transactions on Industry Applications, 2019This paper examines how changing the magnetic orientation of permanent magnets in concentrated winding interior permanent magnet synchronous motors (IPMSMs) affects their demagnetization resistance. We evaluated a prototype for demagnetization at 180 °C that consists of a 130° V-shaped rotor core in which parallelogram magnets with oblique orientation ...

An Improved Rotor Cooling Structure of IPMSM
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019For the interior permanent magnet synchronous machine, the rotor temperature at the axial center is high because of its low axial thermal conductivity. The conventional the rotor structure with axial and radial vent holes has low air velocity in the axial center position, so the cooling performance for the rotor is unsatisfactory.

Sensorless IPMSM based drive for reciprocating compressor
2008 13th International Power Electronics and Motion Control Conference, 2008This paper presents a new algorithm for the position sensorless vector control of the Interior Permanent Magnets Synchronous Motors (IPMSM), which is based on the well-known approach for the Permanent Magnets Synchronous Motors (PMSM), when rotor position and speed information is obtained by using current error between actual and estimated currents ...
