چکیده
The dynamic behaviors of permanent magnetic synchronous motors considering unbalanced pull have been extensively investigated. However, the harmonics and cogging effects are ignored stator rotor assumed to be smooth cylinders. In this research, an analytical expression is obtained. Based on model, motion equations system established. natural frequency frequency-response analyzed by average method, stability periodic solution investigated Routh-Hurwitz criterion. analysis indicates that closely related slot parameters. shows amplitude varies between two static equilibrium points. Besides, when ratio width pitch close peak value, tends increasing obviously. It useful for design magnet with high low vibration.

Analysis of Nonlinear Vibration in Permanent Magnet Synchronous Motors under Unbalanced Magnetic Pull
The vibration and noise of permanent magnet synchronous motors (PMSM) are mainly caused by unbalanced magnetic pull (UMP). This paper aims to investigate nonlinear vibration in PMSMs. Firstly, the analytical model of the air-gap magnetic field with an eccentric rotor in PMSM is studied, and the analytical model is verified by the finite element method. Then the dynamic model of an offset rotor-...
متن کاملDigital Control of Permanent Magnet Synchronous Motors
Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is pro...

متن کاملFinite Element Analysis of Permanent Magnet Synchronous Motors Subjected to Symmetrical Voltage Sags
This paper studies the effects of symmetrical voltage sags on the operational characteristics of a Permanent Magnet Synchronous Motor (PMSM) by Finite Element Method (FEM). Voltage sags may cause high torque pulsations which can damage the shaft or equipment connected to the motor. By recognizing the critical voltage sags, sags that produce hazardous torque variations could be prevented. Simula...
متن کاملAdaptive Voltage-based Control of Direct-drive Robots Driven by Permanent Magnet Synchronous Motors
Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
