Brushless DC-Motor

2020
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

DC Motor Speed Control through AC/DC Converter

2006 IEEE International Conference on Control Applications, 2006
We are considering the problem of DC motors through AC/DC power converters of the Buck-Boost type. The dynamics of the latter are explicitly accounted for in the controller design, unlike in most previous works. The control objectives are twofold: (i) speed regulation, (ii) unitary power factor operation.

Commutation of DC Motors

IEEE Industry Applications Magazine, 2010
The information presented here is generally known to dc motor manufacturers but is not common knowledge to dc motor users. As there is a necessity for the equipment to perform beyond its original specifications and adjustment, commutation issues may arise that could increase maintenance requirements or downtime.

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

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].

DC motor drives

2019
This chapter is intended to provide insight on the design and development of controllers for DC motors, their classification and issues related to the control, power quality improvement and sensors reduction for various domestic, commercial and industrial applications.

DC & AC traction motors

IET Professional Development Course on Electric Traction Systems, 2008
Traction motors provide the motive force for the majority of railway vehicles. This paper looks at the fundamentals of the design and construction of the main DC and AC traction motor types that will usually be encountered in the UK and discusses some of the details that need to be considered.

DC motor cooling considerations

IEEE/IAS Pulp & Paper Industry Technical Paper Conference, 2011
DC motors have been the workhorse of variable speed drives in the paper industry for many years. DC motors in paper mills are usually separately ventilated from a large common air supply. The quantity and quality of the cooling air can have a major impact on the DC motors' performance, operation, maintenance and life between overhauls.
