摘要： Provided is a brake inspection device including: load torque measurement units configured to respectively measure: load torques as a motor is normally rotated and reversely rotated in a released state where an operation of a brake for holding a rotor with respect to a stator of the motor is released; and a load torque as the motor is rotationally driven in either one of a normal direction or a reverse direction in a locked state where the brake is operated; and a determination unit configured to determine a state of the brake based on the load torques measured by the load torque measurement units.

摘要： A device can prevent a failure in the actuation of a braking mechanism, which is caused by adhesion of adhesive substances. The device includes a heating part for heating the braking mechanism, a heat controller for controlling a heating operation of the heating part, a brake controller for actuating the braking mechanism when the heat controller stops the heating operation, and the temperature of the braking mechanism decreases, an actuation delay measuring part for measuring an actuation delay of the braking mechanism when the brake controller actuates the braking mechanism, and a comparison part for comparing the actuation delay measured by the actuation delay measuring part with a reference value of the actuation delay of the braking mechanism.

摘要： Provided is a motor controller including: a rotation control unit configured to control a rotation of a motor; a brake control unit configured to control an operation of a brake for holding a rotor with respect to a stator of the motor; a rotation-state detection unit configured to detect a rotation state of the motor; a timer configured to measure, in a released state where an operation of the brake is released by the brake control unit, a time from an outputting of a command to change over a state of the brake to a locked state to a detection of a predetermined change in a rotation state of the motor by the rotation-state detection unit; and a determination unit configured to determine that a brake operation delay abnormality is present when the time, measured by the timer, is equal to or more than a predetermined threshold.

摘要： A coil bobbin and a brake core are secured to each other readily and more tightly. Provided is an electromagnetic brake including an annular coil bobbin around which an excitation coil is wound, a brake core having an annular recess that accommodates the coil bobbin, and an armature driven by an electromagnetic force generated by the excitation coil. An inner surface of a center hole in the coil bobbin is provided with inner protrusions that protrude radially inward from a plurality of locations at intervals in a circumferential direction and that are pressed onto an outer peripheral surface of a columnar central projection included in the recess when the coil bobbin is press-fitted to the recess of the brake core. The inner protrusions are disposed substantially along the entire length of the coil bobbin in an axial direction thereof.
