Permanent magnet spherical motors (PMSMs) operate on the principle of the dc excitation of
stator coils and three freedom of motion in the rotor. Each coil generates the torque in a …

This paper presents two methods to derive an inverse model in harmonic forms for analyzing
the interactions between the torque/current gains and currents, and for suppressing the …

Smart sensing is a prerequisite to information sharing in intelligent manufacturing where
online measurements of multiple parameters are essential to infer system properties for …

In response to the issues of low tracking accuracy and poor robustness in the trajectory
tracking control of a permanent magnet spherical motor (PMSpM), an active disturbance …

Modular multiphase (MMP) PM motors have the ability to work continuously under a faulty
mode. However, ripples in the spin torque of the motor and unbalanced forces incur rotor …

Simultaneous, parallel or double-sided machining can increase the metal-removal-rate
(MRR) of hard-to-cut materials. This paper presents a direct-drive duplex-face-turning (DFT) …

In this paper, based on the multi-DOF motor, the structure is optimized and gas lubricated
bearings are added, and the structure of the multi-of motor is proposed. Firstly, the basic …

Los esfuerzos por reducir las emisiones de dióxido de carbono a la atmósfera han
impulsado la investigación de nuevas maneras de energizar, por ejemplo, los medios de …

In view of the fact that the transmission mode of the multi-DOF motor hinders its further
development, the gas bearing is applied to the multi-DOF motor to form a new structure of …
