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.

摘要： An electric linear motion actuator includes an electric motor, a motion converting mechanism that converts the rotational motion of the electric motor into a linear motion of a linear moving member, a load sensor that detects the magnitude of the load applied to the brake disk from the linear moving member, and a controller that performs feedback control on the electric motor based on the difference between the load detected by the load sensor and a load command value. The controller reduces the number of revolutions of the electric motor when the linear moving member moves into a predetermined zone immediately before the position where the clearance between the linear moving member and the brake disk becomes zero.

摘要： An electric linear motion actuator includes: a rotary shaft to be driven by an electric motor; a plurality of planetary rollers kept in rolling contact with a cylindrical surface formed on an outer periphery of the rotary shaft; a carrier which retains the planetary rollers such that the planetary rollers are rotatable about axes thereof while revolving around the rotary shaft, and of which axial movement is restricted; and an outer ring member surrounding the planetary rollers and supported so as to be slidable in an axial direction. Helical ribs are formed on an inner periphery of the outer ring member; and circumferential grooves are formed on an outer periphery of each of the planetary rollers so as to be engaged with the helical ribs. A rotation of the rotary shaft is thus converted to a linear motion of the outer ring member.

摘要： An electric brake device includes an electric motor, a braking force application mechanism, a lock mechanism, a temperature sensor for measuring an ambient temperature of a vehicle in which the electric brake device is provided, and a freezing preventive power supply unit. The freezing preventive power supply unit initiates the supply of an electric power to the electric motor or a drive source of the lock mechanism in the event that while the braking force application mechanism applies a braking force and the lock mechanism is held in a locked condition, the temperature sensor detects a preset temperature of the electric brake device immediately before freezing.

摘要： An electric parking brake system includes an electric motor; a linear motion mechanism that converts the rotational movement of a rotor shaft of the electric motor to a linear movement of a slide member to operate a brake; a locking mechanism that fixes a position of the slide member; a control device that controls the electric motor and the locking mechanism; a brake load estimation unit that estimates a brake force; and an electric parking brake operation instruction device that is arbitrary operable. The control device automatically executes a parking brake operation when a stop state of the vehicle is detected even if the electric parking brake operation instruction device is not operated. The automatically applied parking brake force is set to a value smaller than the normal parking brake force applied by the parking brake operation instruction device.

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.
