Abstract

Purpose

The purpose of this paper is to present a developed modelling method of a car starter with permanent magnet commutator motor.

Design/methodology/approach

Mathematical model, algorithm and computational program of electrical and mechanical quantities transients in the system: battery – car starter with permanent magnet commutator motor and planetary gear – combustion engine were developed. Circuit‐field method was applied. Magnetic quantities determined using time‐stepped finite‐element method (with the help of Maxwell software) were used as the parameters of mathematical model equations in circuital part. Program was developed in the Matlab environment.

Findings

The developed mathematical model, the algorithm and the program enable the computations of transients of electrical and mechanical quantities at different ambient temperature, by different swept capacity of the combustion engine as well as by different battery capacity and different charge ratio.

Research limitations/implications

The analysis was carried out on an example of four‐cylinder combustion engine. However, the developed modelling method can be used for analysis of different combustion engines start‐up.

Practical implications

The proposed modelling method is useful for analysis of car starters at the stage of design.

Originality/value

The originality of the work consist in the fact that in the developed model variation of the car starter load torque as well as the variations of the entire mechanical system moment of inertia were taken into account.

Abstract

Purpose

The purpose of this paper is to obtain an accurate methodology for modelling and analysis of the permanent magnet synchronous generator connected to power electronic components.

Design/methodology/approach

This paper presents the methodology of the co-simulation of a permanent magnet synchronous generator. It combines Simulink, Maxwell and Simplorer software to demonstrate the electrical machine behaviour connected with the power electronics’ circuit. The finite element analysis performed on the designed machine exhibit a more accurate behaviour over simplified Simulink models. Results between both simulation and co-simulation are compared to measurements.

Findings

The co-simulation approach offers a more accurate depiction of the machine behaviour and its interaction with the non-linear circuits.

Research limitations/implications

This paper focuses on the interior permanent magnet type of PMSG and its interaction with a passive rectifier (nonlinear circuit).

Practical implications

The advanced capabilities of the co-simulation method allow to analyse more variations (geometry, materials, etc.), and its interaction with non-linear circuits, than previous simulation techniques.

Originality/value

The co-simulation as a tool for analysis and design of systems interconnected with unconventional and conventional electrical machines and prototypes, and the comparison of the obtained results with classical analysis and design methods, against measurements obtained from the prototype.
