“…The peak around 100 Hz need not be mentioned, because it is of little consequence to humans. Figure 10 (b) shows that the SR-EMB has higher natural frequencies than usual [16][17][18]. The SR-EMB does not have any resonance frequency around 1kHz.…”

It is held as fact that Permanent Magnet (PM) brushless motors are less noisy than Switched Reluctance (SR) motors, and many methods have been published to reduce the noise of SR drives.This paper provides a systematic experimental comparison of both drives, and of proposed noisemitigation strategies, in the context of a specific mass-market application: Automotive Electro Mechanical Brakes (EMB). The two motors were designed to fit into the same envelope and to produce similar dynamic performance for the brake system. Sound pressure levels produced by the two motors at key torque-speed points were measured through dynamometer tests under identical conditions. The influence of the hysteresis current and PWM control methods on the acoustic noise was also studied. The acoustic noise was then measured with the EMB systems assembled with the PM and SR motors. Though the measured acoustic noise of the SR motor with dynamometer tests was higher compared to that of the PM motor, the acoustic noise levels of the two EMB systems were found to be similar with only a slight advantage to the PM based system.

“…Among all different kinds of electric motors, Switched Reluctance Motors (SRMs) have many applications because of their special advantages, such as their simple and rugged construction, hazard-free operation and their very low cost [Donovari et al (1994); Lawrenson et al (2002); Cai et al (2003); Anwar et al (2003); Tang et al (2003)]. According to Fig.…”

A thorough analysis of cylindrical shells' dynamical behavior is essential in many different industrial design problems, and particularly in electric motor design. Shell vibration equations form a set of partial differential equations of order eight, where their closed form solution is only known for few special cases with a few known boundary conditions along with many not necessarily realistic assumptions. On the other hand, finite element based numerical solutions does not yield a lumped model that can be regarded as a general solution for natural frequencies of cylindrical shells.In this paper, a neurofuzzy model for natural frequencies of cylindrical shells is developed. At first, natural frequencies are calculated for a wide range of cylindrical shells' dimensions, using either closed form solution or finite element method. Gathered data is exploited for training of a Locally Linear Neurofuzzy Network, which yields a general model for calculation of natural frequencies of cylindrical shells. While the developed neurofuzzy model may be used in different design problems that deals with cylindrical shells, as a case study, the proposed model along with an evolutionary algorithm are utilized in the optimal design of a Switched Reluctance motor.

“…Islam et al investigated the prediction method of magnetically induced vibration using magnetic FEM and analytical model for radial displacement of PMSMs [9]. On the other hand, Tang et al experimentally proposed a prediction method of the magnetically induced vibration in a SRM using an impact hammer [10]. They measured a frequency response function of the motor to predict magnetically induced vibrations.…”

This paper presents a method to predict magnetically induced vibration in a permanent magnet synchronous motor (PMSM) using time stretched pulse (TSP) excitation. The TSP signal has high signal to noise ratio and flat frequency spectrum, and it can be easily generated by MATLAB in order to excite a PMSM. The magnetic forces acting on teeth of a stator are calculated by the magnetic finite element analysis and the Maxwell stress tensor method. The structural transfer function of the motor is determined using the simulated magnetic forces and the measured vibrations when the TSP excitation is applied to the motor. Finally, the magnetically induced vibration of the motor in operating condition is predicted using the identified structural transfer function and simulated magnetic forces.
