permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. one of the interesting applications of such motors is in underwater vehicles. in these cases, reaching to minimum volume and high torque of the motor are the major concern. design optimization can enhance their merits considerably, thus reduce volum...

Biological and engineered motors are surprisingly similar in their adherence to two or possibly three fundamental regimes for the mass scaling of maximum force output (Fmax). One scaling regime (Group 1: myosin, kinesin, dynein and RNA polymerase molecules; muscle cells; whole muscles; winches; linear actuators) comprises motors that create slow translational motion with force outputs limited b...

This paper presents the modular topologies of dual-stator dual-winding permanent magnet (PM) linear motors for compressors used in electrified transportation application. Compared to conventional PM motor compressor, proposed model is designed with same volume but a higher thrust force density and further air pressure cylinder, which are competitive compressor industry. The compact constructed ...

Here we have demonstrated that small amplitude vibration can artificially excite both two dimensional (2D) and three (3D) instability modes. The 2D modes were typical of Tollmien–Schlichting (TS) waves provided the frequency excitation lies within unstable region neutral stability predicted by modal linear theory. However, even if mechanically forced mode was stable bounds curve harmonics gener...

{ We discuss the force-velocity relations obtained in a two-state crossbridge model for molecular motors. They can be calculated analytically in two limiting cases: for a large number and for one pair of motors. The eeect of the strain-dependent detachment rate on the motor characteristics is studied. It can lead to linear, myosin-like, kinesin-like and anomalous curves. In particular, we speci...

Linear sliders are linear actuators using motors. It is used in many applications, such as factory lines and motor cars. In recent years, the demand for smaller semiconductor devices has been increasing due to proliferation of smartphones. High-precision positioning motors needed because manufacturing uses stage with However, have nonlinearity position dependence interlinkage flux. affects prec...
