A Novel Design of Permanent Magnets for the Air Gap Magnetic Field of Hollow-Cup Motor

open access: yesApplied Sciences, 2023
Spacecraft motors are often driven with trapezoidal phase currents to achieve higher output torque. For hollow cup motors (HCM) driven by trapezoidal wave currents, parallel magnetised permanent magnet (PM) motors produce an air gap magnetic field (AMF ...

Performance analysis and optimization of permanent magnet flux switched linear motor for ropeless elevator

open access: yesIET Electric Power Applications, 2023
Permanent magnet linear synchronous motor (PMLSM) is one of the ideal driving sources of ropeless elevators. However, such motors, whether moving magnetic or moving coil, will produce the problem of excessive cost under long travel.
