# Industrial Brushless Servomotors

Elsevier, Dec 22, 1999 - Technology & Engineering - 208 pages
Industrial use of the brushless servomotor, for instance in robotics, is increasing rapidly, because of their low maintenance needs and capabilities at high transient speeds. They offer flexibility and high performance, and advances in power electronics and microelectronics means they are now more affordable.

This handbook gives the user of brushless servomotors a comprehensive guide to their use, including a description of all main features of the brushless motor drive system. Throughout mathematics is kept to a minimum and practical guidance is given based on real-life experience.

Peter Moreton is a Research Fellow at the University of Bristol, having spent time in industry and universities worldwide.

Page 5 - With the first finger in the direction of the field and the second finger in the direction of the current, the thumb indicates the direction of the force.
Page 5 - ... the thumb of the left hand points in the direction of the magnetic force acting on the moving charge, as shown in Fig.
Page 5 - ... in the material. FORCE ON A CURRENT-CARRYING CONDUCTOR IN A MAGNETIC FIELD The current in a conductor is due to the motion of electrons. Therefore, if a current carrying conductor is placed in a magnetic field, there is a force on each moving electron and hence on the conductor as a whole. If a conductor of length /, carrying a current / is placed in a magnetic field B such that the direction of current makes an angle 6 with the direction of /( , then the magnetic force experienced by it has...
Page 5 - B, it is found that the conductor is acted on by a force which is at right angles to both the field and the conductor.
