摘要: An impact power tool includes a brushless motor, a power switch, an output spindle, and an impact mechanism configured to selectively apply rotational impacts to the output spindle when a torque on the output spindle exceeds a torque threshold. A controller is configured to control power delivery to the motor to selectively cause the motor to operate in a first mode for installing a fastener or in a second mode for removing a fastener. In the first mode, the controller is configured to control the motor with a first conduction band value and a first advance angle value during a first time period until a first parameter is reached, and to control the motor with a second conduction band value and a second advance angle value, at least one of which is greater than the first conduction band value and the first advance angle value, after the first time period.

摘要: A control for an electromagnetic holding brake with a coil for releasing the holding brake and maintaining it in the released position, which requires a minimum brake coil voltage to maintain it in the re-leased position, having a DC-DC converter with an input and an output, the DC-DC converter being designed to convert a variable input voltage pre-sent at the input into a predetermined switch-on voltage provided at the output and a predetermined holding voltage provided at the output, the holding voltage corresponding to the minimum brake coil voltage, the DC-DC converter being designed to implement a 2-stage voltage control and, in a first stage, to maintain the switch-on voltage as a regulated DC voltage for a predetermined time, to downregulate the voltage from the switch-on voltage following a predetermined voltage curve to the holding voltage as regulated DC voltage, and to maintain it in a second stage.

摘要: An actuator control device configured to control an operation of an actuator includes: a detection unit and a restriction unit. The detection unit is configured to monitor a battery voltage and to detect a descent time which is a drop time of the battery voltage from a preset first voltage to a second voltage lower than the first voltage. The restriction unit imposes, when the descent time is equal to or longer than a time threshold, a stronger restriction on an operation of the actuator than an occasion of when the descent time is less than the time threshold.

摘要: An impact power tool includes a housing, a motor, a controller, an output member configured to be rotated when the motor is energized, and an impact mechanism configured to rotationally drive the output member. The impact mechanism is configured to selectively apply rotational impacts to the output member when a torque on the output member exceeds a torque threshold. The controller is configured to control the motor during a first phase of operation with open loop control and a baseline conduction band and advance angle setting when a sensed tool operation parameter is one of above or below a threshold value. The controller is configured to control the motor during a second phase of operation with closed speed loop control and an increased conduction band and advance angle setting when the sensed tool operation parameter is the other of above or below the threshold value.

摘要: Described herein is an electric motor assembly for an environmental control system. The electric motor assembly includes a fan configured to rotate to circulate air within a controlled environment chamber of the environmental control system, and an electric motor coupled to the fan and configured to rotate the fan. The electric motor includes a motor controller configured to receive a braking control signal from a sensor associated with the controlled environment chamber. The braking control signal indicates an entrance to the controlled environment chamber is about to be opened. The motor controller is also configured to initiate braking the electric motor in response to receiving the braking control signal.

摘要: A shift range switching control device for switching a shift range by controlling driving of a motor includes a feedback control section, a stationary phase energization control section, and a switching control section. The feedback control section performs a feedback control based on an actual angle of the motor, and a motor speed. The stationary phase energization control section performs a stationary phase energization control which energizes a stationary phase selected according to the actual angle. The switching control section switches the control state of the motor.

摘要: A vehicle brake control device includes an electric motor controlled based on a target energization amount calculated based on an operation amount (Bpa) of a braking operation member. Based on the operation amount (Bpa), it is determined whether or not an inertia compensation control for compensating for the influence of the inertia of a brake actuator is necessary. When the inertia compensation control is determined to be necessary, an inertia compensation energization amount for compensating for the influence of the inertia of the brake actuator is calculated based on a time-series pattern set in advance based on the maximum response of the brake actuator. Based on the inertia compensation energization amount, the target energization amount is calculated. The vehicle brake control device is thus able to generate a braking torque that appropriately compensates for the influence of the inertia of the entire device including the inertia of the electric motor.
