摘要： PROBLEM TO BE SOLVED: To detect any failure or operation abnormality with ease in an eddy-current speed reducer using electromagnets.
SOLUTION: The temperature of or in proximity to an electromagnetic coil is measured, or the value of a current passed through the electromagnetic coil is measured. The measured value is compared with a preset value, and any failure in the eddy-current speed reducer is determined based on the result of the comparison. For example, the eddy-current speed reducer comprises a braking unit which applies braking force to a rotating shaft and releases the application of braking force using electromagnetic fields produced by energization of the electromagnetic coil, a first temperature sensor 12 which detects the temperature of the electromagnetic coil, and a judgment unit which judges the presence or absence of any failure in the equipment based on the output of the first temperature sensor 12.

摘要： PROBLEM TO BE SOLVED: To control the excessive rise of the internal pressure of a stator case, and also to prevent the entrance of dust or moisture from outside.
SOLUTION: A vent hole for sealing a case which stores a permanent magnet is made, and a given length of ventilating pipe is coupled with the vent hole. Since the air goes out or goes in via the vent hole even if the internal pressure of the stator case goes up by any cause such as consecutive braking action, etc., the pressure within the stator case becomes always equal to the pressure (atmospheric pressure) outside the case. Moreover, the open end of the ventilating pipe can be arranged in an optional position by the way of drawing around the ventilating pipe. Thus, it becomes possible to easily prevent dust or water from entering the stator case from outside.

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 control the excessive rise of the internal pressure of a stator case in the so-called whirl retarder. SOLUTION: A vent hole for sealing a case which stores a permanent magnet is made. Then, it is arranged so that air goes out or go in via the vent hole so as to always equalize the pressure within the stator case with the pressure (atmospheric pressure) outside the case, even if the internal pressure of the stator case goes up by any cause such as consecutive braking action, etc. Consequently, even in a retarder which is of such type that the permanent magnet whirls in the rotational direction of the rotor and the internal volume of the stator case is relatively small, it becomes possible to surely avoid the adverse effect of case internal pressure rise.
