    摘要： To provide a numerical controller for a machine tool capable of reducing heat generation and realizing stable heavy cutting, and also capable of realizing efficient light cutting. A numerical controller comprises: first speed change means which changes the feed speed of a feed axis drive motor at the start of cutting to an initial speed lower than a command speed, based on magnetic flux content at the start of cutting; and second speed change means which changes the feed speed from the initial speed to the command speed continuously or intermittently based on time elapsed from the start of cutting and a time constant for change in the magnetic flux content.

    摘要： An object is to provide the numerical control device of a machine tool which can achieve both a reduction in heat generation and stability in heavy cutting. A numerical control device includes a command transmission portion which transmits a speed command value and a magnetic flux command value to the spindle control portion of a machine tool and a storage portion which stores magnetic flux amounts corresponding to tools that may be used in the machine tool. The numerical control device also includes a tool detection portion which detects a tool selected in the machine tool and a magnetic flux amount setting portion which commands the command transmission portion to read, from the storage portion, a magnetic flux amount corresponding to the tool detected by the tool detection portion and to output the magnetic flux amount to the spindle control portion of the machine tool.

    摘要： An angle sensor for an orthopedic rehabilitation device includes a magnet and Hall effect sensor. The magnet is attached to a first member of the orthopedic rehabilitation device, and the Hall effect sensor is attached to a second member of the orthopedic rehabilitation device. The Hall effect sensor detects the presence of a magnetic flux created by the magnet, and produces an output voltage signal that changes as a function of the magnetic flux detected by the Hall effect sensor. As the first member rotates relative to the second member, the magnet rotates relative to the Hall effect sensor, which causes a change in the magnetic flux detected by the Hall effect sensor. The change in magnetic flux causes a change in the magnitude of the output voltage signal generated by the Hall effect sensor, which is converted into an angular equivalent.
