The considered converter-fed permanent magnet motor could alternatively be operated in two basically different states − the vector control mode or alternatively the brushless dc, also known as electronically commutated mode. Several quality aspects concerning the system performance have been comparatively investigated in practical as well as theoretical manner. Focus is thereby given to the num...

The Brushless DC (BLDC) motor is a simple robust machine which has found application over a wide power and speed of ranges in different shapes and geometry. This paper briefly reviews the fundamentals behind the motor and also the different types of BLDC motors with different geometries and then presents a new configuration for BLDC motor/generator, which does not use a permanent magnet in the ...

The faulty performance of permanent-magnet (PM) brushless dc motor drives is studied under one and simultaneous two open-switches faults conditions. This DC motor is supplied with a three phase two level six IGBT voltage source inverter. The three phases currents mean values of the DC motor are used as diagnostic indices. A knowledge algorithm is based to get information on which IGBT is in ope...

Electrical motors drive a variety of loads in today’s world. Almost every industrial process relies on some kind of electrical motors and generators. There exist billions electric motors used in different applications all over the world. Majority of them are small fractional HP motors use in household appliances. However, they used about 5% of the electricity used by the motors. Three phase mot...

This paper presents digital speed control of permanent magnet brushless dc motor using TMS320F2812 DSP controller. The DSP controller used here has the special features for digital motor control. Control algorithms used for the speed control has been implemented by assembly language programming in TMS320F2812 DSP controller. According to the input command, feedback and the control algorithm, th...

This paper presents performance analysis of permanent magnet brush less dc motor (BLDC) using FEA based CAD package MagNet 6.13.First the characteristics of the standard BLDC motor is analysed. Then the design modifications are introduced and the performance of the machine is analysed. Based on the results optimum design is obtained.

Permanent magnet machines are very suitable for Electric vehicles and Motor pump applications because of their simple construction, ease control high efficiency. Among the different Magnet Brushless DC motors (PMBLDC) as well permanent particularly EV owing to high-speed performance constant speed-torque features. In this paper, PMBLDC motor is modelled analysed mathematically using its equival...
