A Hybrid Model of a Brushless DC Motor

2007 IEEE 22nd International Symposium on Intelligent Control, 2007
This paper presents a novel approach to modeling of a Brush-Less Direct Current Motor (BLDCM) driven by an inverter using hybrid systems theory. Hybrid systems combine continuous and discrete (event-based) dynamics, which is exactly the case in an inverter-driven BLDCM.

Brushless DC Motors

2003
Brushless DC (BLDC) motors, also called permanent magnet synchronous motors, are used in direct-drive applications mainly due to their large torque producing capability. Compared to conventional DC motors, they have no brushes or mechanical commutators, which eliminates the problems due to mechanical wear of the moving parts [68, 74].

Definition of the brushless DC motor

Conference Record of the 1988 IEEE Industry Applications Society Annual Meeting, 2003
The authors assert that previously available definitions of a brushless DC motor are inadequate to distinguish it from other types of brushless motors in the industry. A formal definition of a brushless DC motor is proposed. The definition includes the components of the motor and the types of circuits to energize the stator windings. >

Brushless DC motor selection

Proceedings:Electrical Electronics Insulation Conference and Electrical Manufacturing & Coil Winding Conference, 2002
This paper investigates the process of brushless DC motor selection through the specification of load torque and the desired load motion as a function of time. The peak and RMS torque requirements of the application are discussed along with the procedure to find the correct motor size and performance. Gearing and power transmissions are also considered

Torque controller for brushless DC motors

IEEE Transactions on Industrial Electronics, 1999
A high-performance torque controller is proposed for three-phase brushless DC motor drives. The strategy is based on variable-structure control and a new synchronous reference frame is utilized. Advantages over conventional strategies include improved dynamic performance, reduced acoustic noise, improved drive efficiency and enhanced inverter ...

Control of permanent-magnet brushless DC motors

Proceedings of the 2001 American Control Conference. (Cat. No.01CH37148), 2001
We design, test, and compare different control algorithms for high-performance electric drives with permanent-magnet brushless DC motors. The major emphasis is placed in the analysis and design of closed-loop systems by synthesizing and testing different control laws.

Performance improvement of brushless DC motor

2013 International Conference on Energy Efficient Technologies for Sustainability, 2013
Brushless dc (BLDC) drives have received significant attention, owing to their high efficiency, electromagnetic interference, and high mechanical reliability due to the absence of brushes. This paper discusses random pulse width modulation control for a BLDC motor drive; Boost and Buck boost converter control of a BLDC motor drive and a BLDC drive ...

Undriven vibrations in brushless DC motors

2000 Asia-Pacific Magnetic Recording Conference. Digests of APMRC2000 on Mechanical and Manufacturing Aspects of HDD (Cat. No.00EX395), 2001
This paper investigates motor vibrations due to reluctance forces. Forcing frequencies caused by motor design, part geometries, and errors in assembly are tabulated for several popular pole/slot ratios. Motor torque and translational force fluctuations are found to exhibit a rich set of shapes and frequencies, especially when multiple defects occur ...
