摘要： PROBLEM TO BE SOLVED: To suppress drag torque generated during braking off without degradation of a braking force during braking on as much as possible. SOLUTION: This single-line revolving eddy current type reduction gear has a structure so that the entire external surface of a support material 5 having a box shape in cross section, or at least part of an area on a switch plate 4 out of the external surface of the support material 5 coming into contact with the rear end of a rotor 1 in the rotational direction of the rotor 1 is coated with a surface treated layer 11. It is possible to suppress a magnetic flux generated from a permanent magnet during braking off without degradation of the braking force during braking on, and reduce the magnetic flux naturally leaking from the switch plate to the cylindrical part of the rotor as the magnetic flux which is generated from the permanent magnet during braking off is reduced, thereby suppressing the drag torque.

摘要： PROBLEM TO BE SOLVED: To prolong service life, against deterioration and damage of a covering layer provided on a surface facing a magnet at the cylindrical section of a rotor and including a copper or copper alloy layer. SOLUTION: The thickness of a copper layer 11b at the crosswise central section at which magnetic lines concentrate in a plated layer 11, including the copper layer 11b layer provided on the surface facing the permanent magnet 3a, is formed so as to be smaller than that of the copper 11b layer on ether side, or null. It is thus possible to prolong the service life, against deterioration and damage, of the covering layer including the copper or copper alloy layer at the internal surface of the cylindrical section of the rotor so as to correspond to vehicle traveling service life.

摘要： PROBLEM TO BE SOLVED: To estimate braking force that changes with RPM of a rotor and the elapse of time, with high accuracy.
SOLUTION: An eddy current decelerator 13 is provided with a rotor 2, connected to a rotary shaft 1 and made of a conductive material, and magnetic force generating means 5, 5a, 5b and 9 disposed on a fixed side. The decelerator 13 applies a magnetic force, generated in each of the magnetic force generating means 5, 5a, 5b and 9 to the rotor 2, to causing an eddy current to be generated inside the rotor, thereby generating a braking force. In the decelerator 13, correlation has previously been obtained between a rotor temperature and the braking force of the eddy current decelerator, and the estimated braking force is calculated, on the basis of the correlation previously obtained and the detected rotor temperature.

摘要： PROBLEM TO BE SOLVED: To provide an eddy-current speed reducer wherein the height of permanent magnets and the gap between the permanent magnets and a switch plate are defined and thereby magnetic flux which escapes from the switch plate to cases before and in the direction of rotation of a rotor is suppressed when braking is applied for the enhancement of braking torque and permanent magnets for use in the speed reducer.

摘要： PROBLEM TO BE SOLVED: To estimate the temperature of a rotor with accuracy by detecting the actually-measured temperature of an eddy current system of speed reducer or its vicinity thereby computing the initial temperature of the rotor, and further, using an approximate expression.
SOLUTION: This is a method of estimating the temperature of the rotor of the eddy current system speed reducer, which switches off the braking just before the rotor reaches the tolerable upper limit value. The actually measured temperature of the eddy current system speed reducer at switching or its vicinity is detected. The initial temperature of the rotor at brake ON switching is computed based on the correlative relation between this actually measured temperature and the rotor temperature. The rate of change of the initial temperature and the first temperature change rate approximate expression are decided from this rotor's initial temperature, and the estimated temperature of the rotor from the time of brake ON switching to the time of switching off the braking is computed, using the above rotor initial temperature, the first temperature change rate approximate expression, and the second temperature change rate approximate expression decided beforehand. This way, the rotor temperature can be estimated with accuracy by appropriately correcting the rate of temperature change, considering the influence of the temperature at brake switching or the influence of the number of revolutions.
