Title: Motor driving device
Inventor: HARA YASOHACHI
IPC: H02P27/06
Filed: 2006-11-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a motor driving device with which erroneous determination of the locking status of a motor can be prevented.  <P>SOLUTION: The motor driving device includes an inverter comprising a plurality of switching elements, an energization control means of controlling the energization of the inverter, a position detecting means for detecting the position of a rotor of the motor, a rotation state detecting means for detecting the rotation state of the motor on the basis of a position signal to be output from the position detecting means, and a locking determining means for determining whether the motor is in a locked state on the basis of a rotating state signal to be output from the rotating state detecting means. When the motor continues the predetermined rotating state for not less than a determining time for previously set locking detection, the locking determining means determines that the motor is in a locked state. Thus, since a determining time is set so as to be long when the motor starts and to be short when the motor is normally rotating, an erroneous detection of the locked state can be previously prevented.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a motor driving device that enables the enhancement of the efficiency of a motor and stable vibration damping control.  <P>SOLUTION: A torque command used for the computation of a voltage command for a step-up converter is generated by adding vibration damping torque Tcct to target driving torque. A target value Tcct* of the vibration damping torque Tcct is set according to the state of a relevant vehicle detected based on input signals from various parts of the vehicle regardless of a fluctuation component of number of revolutions contained in the number of revolutions of a motor. When the target value Tcct* of vibration damping torque is increased in correspondence with change in the state of the vehicle, the vibration damping torque Tcct is increased according to a rate of increase set according to the rate of change in the band of fluctuation in the vibration of the vehicle. This makes it possible to avoid an insufficiency of output torque and further prevent a voltage command from being uselessly set higher than motor driving voltage required to damp the vibration of the vehicle. As a result, the stability of vibration damping control can be ensured and further power loss in a voltage converter can be reduced.  <P>COPYRIGHT: (C)2008,JPO&INPIT
