摘要： This invention relates to a mechanism for positioning an output member of a mechanical system and in particular a mechanical system that has backlash present. The mechanism has a step motor, regulated by control means, connected to the output member by a mechanical transmission. The control means delivers units of electrical energy to the step motor in response to a number of steps specified to be moved. The control means also has means for detecting whether the step to be performed by the step motor is a single remaining step or single step only. The control means responds to detection of the single remaining step or detection of the single step only by applying a unit of energy to the step motor at a rate that is substantially slower than the rate that would be applied for the other steps.

摘要： The present disclosure may provide a shift range control apparatus that controls on-off operations of switching elements in a driver circuit, drives a motor, and switches a shift range. The shift range control apparatus may be configured to determine an abnormality of a rotation angle sensor detecting a rotation angle of the motor, to control a drive of the motor using a detection value, and to execute a control which switches an energization phase every energization phase switching period without using the detection value of the rotation angle sensor in response to that the rotation angle sensor is abnormal.

摘要： A motor driving apparatus and a home appliance including the same. The motor driving apparatus includes a temperature sensing unit to sense a compressor temperature, an inverter including a plurality of switching elements to convert a direct current (DC) voltage into an alternating current (AC) voltage and to supply AC voltage to a motor used to drive the compressor, and a controller to control the inverter. The controller performs control to apply motor preheating current for preheating of the motor during a first period before startup of the motor, and varies depending on the sensed temperature a time during which the motor preheating current is applied or a current application level. A reduction in power consumption during the preheating of the compressor is achieved.

摘要： A method for detecting stall of a multiphase motor operated in a sinusoidal micro-stepped mode. The method comprises: a) measuring at least one phase current and/or measuring the sum of all phase currents at regular time intervals synchronous with the micro-steps, b) calculating the difference between the measured phase current at a first moment and the measured phase current of the same phase at a previous moment and/or the difference between the measured sum of all phase currents at a first moment and the measured sum of all phase currents at a previous synchronous moment, c) analyzing the series of obtained current differences so as to generate a stall detection signal.

摘要： The present invention provides a linear actuator including a motor; a linear driving unit coupled to the motor and including a magnet; a sensor unit configured to sense a change amount of magnetic flux depending on a position of the magnet and convert the sensed change amount of magnetic flux into measured voltage data; a data unit in which reference voltage data corresponding to the change amount of magnetic flux depending on a position of the magnet is stored; and a judging unit configured to compare the reference voltage data with the measured voltage data at the corresponding position of the magnet. The present invention is advantageous in that, by compensation-controlling a position of the motor, feedback control may be performed in the step motor to secure performance of the product to which the present invention is applied.
