Abstract As an important power component of the material conveying system, motor will inevitably cause vibration mechanical structure when rotating, thus affecting stable operation motor. Most systems have high requirements for level, and usually take performance electrical as evaluation criteria same level. A nonlinear terminal sliding mode controller is proposed to solve phase delay problems ...

This paper presents the closed-form analytical determination of current signature a surface-mounted permanent magnet synchronous motor drive controlled by means field oriented control strategy, when fault occurs in one or more sensors. Both DC offset and gain for all phase sensors are considered. The proposed model includes response loop related gains, eliminating need voltage complicated state...

Permanent magnet Vernier (PM-V) machines, at low power levels (few kWs), have shown a great potential to improve the torque density of existing direct-drive PM machines without much compromising on efficiency or making machine structure more complicated. An improved is very desirable for offshore wind applications where size an increasing concern. However, relatively poor factors PM-V will incr...

Permanent magnet synchronous motors (PMSM) are known for their type whose magnets located on the rotor surface and this motor type, which is called mounted (SPM), generates torque due to rotor. Based equations, since there only q axis current value of magnetic flux linkage, d kept at 0 maximized controlled, I_d = control technique. However, reluctance generated in interior permanent (IPM) induc...

Drive motors in certain applications often require heavy load starting or short-time overload operation, so the limiting output capacity of motor is worthy attention. In this paper, torque and input current low-speed high-torque external rotor surface-mounted permanent magnet synchronous motor(SMPMSM) under <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/19...

In this paper, we present a novel method for 3D pedestrian navigation of foot-mounted inertial systems by integrating a MEMS-IMU, barometer, and permanent magnet. Zero-velocity update (ZUPT) is a well-known algorithm to eliminate the accumulated error of foot-mounted inertial systems. However, the ZUPT stance phase detector using acceleration and angular rate is threshold-based, which may cause...

In engineering application, the hot press assembly technology is often used to improve stability of rotor structure, but conventional design methods cannot effectively evaluate influence this process on strength, which easily causes strength exceed its safety margin range, and seriously it will lead failure structure. This paper takes cylindrical magnet surface-mounted high-speed permanent sync...

In a permanent magnet synchronous motor where inductances vary as a function of rotor angle, the 2 phase (d-q) equivalent circuit model is commonly used for simplicity and intuition. In this article, a two phase model for a PM synchronous motor is derived and the properties of the circuits and variables are discussed in relation to the physical 3 phase entities. Moreover, the paper suggests met...

Wireless capsule endoscope achieved great success, however, the maneuvering of wireless capsule endoscope is challenging at present. A magnetic driving instrument, including two bar magnets, a stepper motor, a motor driver, a motor controller, and a power supplier, was developed to generate rotational magnetic fields. Permanent magnet ring, magnetized as S and N poles radially and mounted spira...
