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 ...

Sensorless PM brushless DC motor drives

IEEE Transactions on Industrial Electronics, 1996
To control PM brushless DC motors, position and speed sensors are indispensable because the current should be controlled depending on the rotor position. However, these sensors are undesirable from standpoints of size, cost, maintenance, and reliability. There are different ways of approaching this problem, depending on the flux distribution. The paper

Strange attractors in brushless DC motors

IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 1994
Deals with the open-loop dynamic characteristics of smooth-air-gap brushless DC motors. The steady-state characteristics of these systems, subject to constant input voltages and constant external torques, are formulated, whereby it is shown that the presence of viscous damping friction can cause the system to possess multiple physical equilibria ...
