Reluctance Synchronous Machines and Drives

1996
Abstract Reluctance synchronous machines (RSMs) and drives include a multitude of machine topologies in terms of rotor, stator windings, and stator current control. Line-start (constant speed) and inverter-fed (variable speed) applications are easily achieved in a power range from a few hundred watts to megawatts.

Induction and synchronous reluctance motors comparison

2008 34th Annual Conference of IEEE Industrial Electronics, 2008
The aim of this paper is to investigate and compare the performances of two induction motors and two transverse laminated synchronous reluctance motors (induction motor nameplate data: 2.2 and 4 kW, 380 V, 50 Hz, 4 pole). Each induction motor is compared with a synchronous reluctance motor, that has the same stator lamination and winding, but ...

Efficient control of reluctance synchronous machines

IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002
This paper shows that maximum efficiency control (ME) in reluctance synchronous machines (RSM) belongs to the class of constant angle control strategies. It is also shown that for all constant angle control strategies, efficiency is constant and independent of torque (current), being only a function of speed.

Sensorless control of synchronous reluctance motors

2017 IEEE Transportation Electrification Conference and Expo, Asia-Pacific (ITEC Asia-Pacific), 2017
A new sensorless control method for synchronous reluctance motor(SynRM) is proposed. The speed and rotor position estimation are based on the stator voltage equation. The speed is estimated using the stator voltage and current. The rotor position is obtained by the speed integral.

Reluctance synchronous motors modelling and analysis

2012 International Conference on Applied and Theoretical Electricity (ICATE), 2012
This paper presents a possibility for the theoretical and experimental modelling and analysis of the reluctance synchronous motors asynchronous starting. In the first part of the paper the two axes theory mathematical model of the reluctance synchronous motor is presented.

Composite powder metal synchronous reluctance machine

IEEE International Electric Machines and Drives Conference, 2003. IEMDC'03., 2003
A new methodology for producing a synchronous reluctance machine (SyRM) has been developed. The new methodology involves fabricating powder metal (P/M) disks 8 mm to 25 mm thick which are constructed of sintered together ferromagnetic and nonferromagnetic powder metal layers. The advantages for adopting the composite P/M SyR rotor over the conventional

Pulsating losses in synchronous reluctance motor

Seventh International Conference on Electrical Machines and Drives, 1995
The aim of this paper is to calculate the pulsating losses at laminated pole-faces in synchronous reluctance motors. To determine these losses, it is necessary to calculate the values of magnetic flux density on both sides of the air gap: near the rotor surface and near the stator surface.

CAPACITOR BRAKING OF SYNCHRONOUS RELUCTANCE MOTORS

Electric Machines & Power Systems, 1993
ABSTRACT Capacitor braking, a well-known low-loss braking method of Induction ma-chines, Is described in connection with reluctance machines. To represent the main features of capacitor braking of synchronous reluc-tance motors, three dimenslonless quantities are introduced: a frequency parameter, a reactance parameter and a resistance parameter.

Torque ripple in synchronous reluctance motor

MELECON '98. 9th Mediterranean Electrotechnical Conference. Proceedings (Cat. No.98CH36056), 2002
The paper describes the calculation and reduction of torque ripple in a synchronous reluctance motor (SRM). The analysis is based on finite element modeling and proposes a method of dynamic torque characteristic calculation. The mutual connection between static and dynamic torque characteristic is also established.
