Improve the performance characteristics of the IPMSM under the effect of the varying loads

Abstract

Studying the dynamic performance is very important for improving the performance of the electrical machines. The sudden applied or removal the load is very critical for the electrical machines. It may lead to some problems in it's as, mechanical stress, surge current, increase the losses and decrease the motor life time. So, this paper studied this problem and constructed proposal model to reduce the effect of this problem on the electrical machines. This occurred through comparing between the effect of the dynamic load, sudden applied and removal loads on the performance characteristics of interior permanent synchronous motor (IPMSM) with proposal model and with classical model in the constant flux region and in the field weakening region. The simulation is done through the MATLAB program. The simulation shows the effectiveness of the proposal model on the performance characteristics of the IPMSM. With proposal model, the overshooting and under shooting of the motor speed are reduced. Rise time and settling time are improved, the response of the motor torque for load variations is improved and the stator currents are decreased. In this model, the space vector pulse width modulation is used to controlling the inverter which used to drive the IPMSM.

Towards End-to-End Deep Learning Performance Analysis of Electric Motors

“…The latter is extremely important for the design of high-density high-efficiency electric machines that have various industrial applications. Interior permanent magnet synchronous motors (IPMSMs) are highly valued for high power density, torque density, and energy efficiency owing to the properties of strong rare earth permanent magnets (PMs) [11,12]. They are widely used as traction motors for transport vehicles and in-wheel motors for electric vehicles [13].…”

A flexible virtual inertial control algorithm for ship with propulsion load and pulse load

“…Therefore, a large amount of inherent mechanical inertia is not fully obtained by the DC grid. Although there are many methods that can be used to improve the performance of electric propulsion systems [14], the task of ensuring the power supply of pulse weapon loads is higher than the maintenance of electric propulsion energy system performance under certain operating conditions such as battle circumstance. At present, when there is a power imbalance in the MCDC bus, the power difference of the system is usually balanced by charging and discharging the energy storage system paralleled on the DC side [15].…”

“…In order to improve the power quality of the DC bus and realize the flexible power adjustment between the power supply, the PML and the high-power PL, this article designs a control algorithm based on virtual inertia. Different from the idea of using energy storage to improve bus voltage transient process in reference [12][13][14][15], the innovation of this article is that only the control strategy of propulsion load needs to be improved, and it does not rely on additional energy storage and auxiliary converter. The proposed control strategy can coordinate different propulsion loads to participate in bus voltage regulation without relying on communication and save energy storage capacity configuration compared to [12].…”
