We derive the mathematical model of this class of motors. Then we design the proposed control schemes in original coordinates, i.e. a dq transformation is not required. We formally solve the velocity and position regulation problems. A pendulum is included as the load in the position control problem. In this chapter we include sketches of the stability

A Hybrid Model of a Brushless DC Motor
2007 IEEE 22nd International Symposium on Intelligent Control, 2007This 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.

Definition of the brushless DC motor
Conference Record of the 1988 IEEE Industry Applications Society Annual Meeting, 2003The 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 (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].

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, 1999A 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 ...
