A Variable-Speed Traction Drive with Internal Spherical Disks. Mechanism of Traction Drive and Method for Calculating Power Transmission Efficiency.

Intelligent-speed-increasing Spindle Using Traction Drive

INTRODUCTION Recently, a milling for die using a small end mill of diameter less than 1 mm is increased, because sizes of plastic mold parts such as connectors for an IT and an electronics becomes micro extremely. In general, a tool life is long and a good cut surface is obtained as a cutting speed is high. A speed-increasing spindle, which is attached to a shank may be used to increase the cut...

Design and Simulation of Double Loop Control for Power Converter Fed Variable Speed DC Drive

Kinematic Creep in a Continuously Variable Transmission: Traction Drive Mechanics for Cobots

Two continuously variable transmissions are examined, one that relates a pair of linear speeds and another that relates a pair of angular speeds. These devices are elemental in the design of cobots, a new class of robot that creates virtual guiding surfaces to aid a human operator in assembly tasks. Both of these transmissions are traction drive mechanisms that rely on the support of either lat...

Modern Topology& Thermal Analysis of Drive for Variable Speed Pumped Storage Power Plant

Given the significant power generation and consumption of variable-speed pumped storage power plants (VSPSPs), it is crucial to enhance drive methods and decrease drive losses, thereby increasing productivity. This paper proposes the topology for VSPSP drivers with two level voltage source converters (2LVSC) with 6+1 converters. Hydraulic and electrical VSPSP models are presented, following whi...

Development of Traction Drive Motors for the Toyota Hybrid System

In terms of preventing global warming and conserving natural resources, automobiles are playing an increasingly critical role. To reduce the CO2 produced by automotive vehicles, fuel efficiency must be improved while cleaning exhaust gases as well as ensuring safety. At Toyota Motor Corporation, solving environmental issues has been being one of our most important tasks, and this focus enabled ...
