摘要： An electric brake system includes a plurality of planetary rollers kept in rolling contact with the radially outer surface of a rotary shaft, a carrier which is restrained from axial movement, an axially movable outer ring member, and a friction pad provided at the axially front end of the outer ring member. The rotation of the rotary shaft is converted to axial movement of the outer ring member, thereby pressing the friction pad with the outer ring member. The brake system further includes a reaction force receiving member provided axially rearwardly of the outer ring member for receiving an axial rearward reaction force applied to the outer ring member when the friction pad is pressed by the outer ring member. A displacement sensor measures the displacement of the reaction force receiving member, thereby detecting the pressing force of the friction pad.

摘要： A magnetic load sensor unit is provided which can detect a load with a minute movement of its part, and which is durable and less likely to be influenced by temperature. The sensor unit includes a flange member (1) deflectable when an axial load is applied, a support member (2) supporting the flange member (1), a magnetic target (3) which generates a magnetic field, and a magnetic sensor (4) for detecting the magnetic field generated by the magnetic target (3). The magnetic target (3) and the magnetic sensor (4) are fixed to the flange member (1) and the support member (2), respectively, such that when the flange member (1) is deflected, the magnetic target (3) and the magnetic sensor (4) move relative to each other, whereby magnitude of the load can be detected based on the magnetic field detected by the magnetic sensor (4).

摘要： A motor drive device is provided which is able to reduce loss between a drive power source and a controller. The motor drive device includes a plurality of motors, a single drive power source which drives these motors, and a controller which controls energizing times during which motor coils of the plurality of motors are energized, by a PWM drive method. The controller includes phase shift portion which sets a PWM signal for causing a current to flow to the motor, into a phase different per motor. By the phase shift portion setting the PWM signal for causing a current to flow to the motor into a phase different per motor, so-called overlap of energizing times of currents is avoided.
