The spindle: a dynamic assembly of microtubules and motors

Nature Cell Biology, 2001
In all eukaryotes, a microtubule-based structure known as the spindle is responsible for accurate chromosome segregation during cell division. Spindle assembly and function require localized regulation of microtubule dynamics and the activity of a variety of microtubule-based motor proteins.

Spindle motor with soundproofing

The Journal of the Acoustical Society of America, 1998
A spindle motor comprises a soundproof wall formed on a stator outside a peripheral surface of a rotor. Noise generated inside the motor during the operation is cut off by the wall to be reduced remarkably. Since the soundproof wall has no influence on the volume of the motor, a slim-type motor can be realized.

Performance Comparison of Different IPM Motor Topologies for Spindle Motor Drives

IECON 2021 – 47th Annual Conference of the IEEE Industrial Electronics Society, 2021
In this study, six promising interior permanent magnet (IPM) motors are designed as a spindle motor for computer numerical control (CNC) milling machine application. An existing surface-mounted permanent magnet (SPM) motor in a CNC is selected for a baseline motor.

Chemical Biology of Mitotic Spindle Assembly Motors

2022
Mitotic kinesins play essential roles during mitotic spindle assembly and in ensuring proper chromosome segregation. Chemical inhibitors of mitotic kinesins are therefore valuable tools to study kinesin function in vitro and in cells. Because cancer is a disease of unregulated cell division, inhibitors also represent potential chemotherapeutic agents ...

Motors involved in spindle assembly and chromosome segregation

Current Opinion in Cell Biology, 1996
During the past two years, major advances have been made in our understanding of the role of motor proteins in chromosome-microtubule interactions in the spindle. The discovery of kinesin-like proteins (KLPs) associated with chromosome arms has shed some light on the mechanism of chromosome congression and the establishment of spindle bipolarity ...

Dissecting the role of molecular motors in the mitotic spindle

The Anatomical Record, 2000
Accurate segregation of genetic material during both mitosis and meiosis is essential for the viability of future cellular generations. Genetic material is packaged in the form of chromosomes during cell division, and chromosomes are segregated equally into two daughter cells by a dynamic, microtubule-based structure known as the spindle.

Disk drive spindle motors and their controls

IEEE Transactions on Industrial Electronics, 1996
Disk drives require very high-precision spindle motors for fast and accurate access of data. As storage capacity and access rate increase, more demands are being made of spindle motors with respect to both electrical and mechanical performances. For error-free operations, spindle motors are required to comply with a host of requirements, such as run ...

Effectof Unbalanced Magnetic Pull In Spindle Motors

1997 IEEE International Magnetics Conference (INTERMAG'97), 1997
This paper analyzes the effects of the unbalanced-magnetic-pull developed in spindle motors for hard disk drives. An analytical technique is used in the investigation which is based on magnetic circuit and field theory. Computational results show that the UMP development is closely related to the magnetic structure, armature winding and armature ...

An evaluation method for spindle motor runout measurement

2009 Asia-Pacific Magnetic Recording Conference, 2009
In order to study the spindle motor vibration characterization, the runout of the motor must be measured accurately. In this paper, a method based on measurement uncertainty is presented to evaluate different measurement systems performance and measurement confidence. The system was developed based on optical interference technology. The spindle runout
