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 ...

Performance improvfment of spindle motor for DVD drive

IEEE International Magnetics Conference, 1999
The brushless spindle motor is widely used for the DVD application. The performances of reading and writing for DVD drive are highly dependent on the dynamic characteristics of this motor. In this paper, a spindle motor with 12-pole, 9-slots, radial winding and driven by the 3-phase circuit is investigated.

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 ...

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.

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

Robust design of a spindle motor: a case study

Reliability Engineering & System Safety, 2002
Robust design is the process of minimising variability of products and processes in order to improve their quality and reliability. In recent years, it has seen wide spread application in many fields such as mechanical [J Quality Technol 24 (1992) 22], chemical [Quality Engng 9 (1997) 391] and civil [Quality Engng 9 (1997) 441] engineering.

Model for the ? motor stimulation in chelonian muscle spindles

Biological Cybernetics, 1977
A previously proposed model to simulate the behaviour of the chelonian muscle spindle during mechanical stretch has been extended to include the properties of the spindle during activation of the intrafusal muscle fibres. It is assumed that the overall transfer function of the non-activated spindle can be entirely ascribed to the visco-elastic ...

Ultrasonic motorized spindle with hydrostatic bearings

Russian Engineering Research, 2016
Ultrasonic and acoustic axial spindle oscillations improve the productivity and product quality in machining, reduce the cutting forces, and increase the tool life in the grinding, milling, and boring of structural components, including those made from materials that are hard to machine.
