Numerical models are developed to predict the electromagnetic vibration and noise of permanent-magnet direct current (PMDC) commutator motors when both rotor eccentricities and glue effects are involved. Finite-element method (FEM) and boundary-element method (BEM) are combined to analyze the electromagnetic, mechanical, and acoustical characteristics of the studied motor. By using the finite-element method, an electromagnetic field considered as the electromagnetic vibration and noise sources of the motor is calculated in the two-dimensional air-gap region. Based on the electromagnetic field, the radial and tangential magnetic forces exciting the structure of the motor are then obtained in the time and frequency domains. Consequently, the transient responses (accelerations) of the motor are simulated by applying the magnetic forces on the three-dimensional dynamic-structure finite-element model of the motor. Furthermore, the sound pressures radiated from the vibrating surface of the motor can be obtained by using the boundary-element method in the frequency domain. The numerical results agree well with those measured in the laboratory. The present research reveals that the static eccentricity distorts the distribution of the magnetic forces in the spatial domain. And the distorted magnetic forces mainly exaggerate the accelerations of the motor for the frequency range which is lower than the natural frequencies of the motor. In addition, the epoxide-resin glue between the permanent magnets and the stator can influence the vibrational and the acoustical characteristics of the motor.Index Terms-Boundary-element model, finite-element model, permanent-magnet direct current commutator motor, vibration and noise.

“…Like all permanent magnet motors, if the single-phase PM synchronous motor has to be utilized in a self-starting mode, usually problems occur [7][8][9][10]. The starting behavior of this motor is fully dependent on the initial rotor position θ o , load inertia τ L and friction k B .…”

Self-starting single-phase Permanent MagnetSynchronous Motors (PMSM) are widely accepted as low-power motors in many domestic appliances. In the paper a hybrid analytical-FEM approach for full performance analysis of a PMSM is presented. At the beginning, the magnetic circuit theory as an essential approach and Finite Element Method (FEM) as a powerful numerical approach are employed for determination of the most important parameters and steady-state characteristics. After, the calculated results are implemented in a simulation approach based on a MATLAB/Simulink environment. The final results are the dynamic characteristics, developed for variety of the motor starting conditions. On the basis of the determined characteristics, the full performance analysis, including steady-state and transient operation of the studied motor is carried out.

Photovoltaic (PV) powered submersible water pumps are the need of the hour for the remote rural areas. Permanent magnet brushless dc (PM BLDC) motor is a suitable candidate for this application, since it offers high efficiency. However, the cost of rare-earth permanent magnets is high which pave the way for the use of low-cost ferrite magnets. The motivation behind this paper is to asses the design feasibility to develop a low-cost BLDC motor for PV submersible pump. Hence, 2D-FEM aided analysis of single, three phase spoke (ST) and surface mounted (SM) BLDC motor is carried out and the results of the comparison are presented. In addition, the design aspects of single phase ST and SM BLDC motor with tapered and asymmetric pole shoe design for the 100 mm bore-well PV based submersible BLDC motor water pumps are also presented.
