摘要： A motor control device includes an estimator for estimating a rotor position of a motor having a salient pole by using a value corresponding to a q-axis inductance of the motor as an operation parameter where an estimated axes for the control corresponding to d-q axes are ³-´ axes, and a controller for controlling the motor based on the estimated rotor position. The estimator generates a deviation between a d-axis and a ³-axis by performing the estimation of the rotor position based on a value between a real q-axis inductance and a real d-axis inductance of the motor adopted as the operation parameter. The controller controls the motor so that a ³-axis component of a motor current supplied to the motor is maintained to be a predetermined value of zero or close to zero regardless of a value of a ´-axis component of the motor current.

摘要： The present invention discloses an apparatus and a method for controlling the rotation speed of a direct-current motor armature (113), which is coupled to an adjustable power supply (102), by measuring a D.C. motor's armature voltage (104) and current (108) and measuring its rotation speed using a Hall-effect sensor (109) enable a particular motor's characteristic equation to be determined empirically. After the equation that models (106) a motor is determined, rotation speed can be determined between Hall-effect sensor signals using real-time measurements of armature voltage and current, which are substituted back into the equation. Current and/or voltage can also be adjusted to increase, decrease or maintain rotation speed.

摘要： The invention relates to a method for determining the position of the drive of an electric machine (10) such as a motor from the applied current (30, 32, 34), wherein for a secure operation, the position determination of the drive is carried out on two independent paths or channels and subsequently both the measured values are combined and cross-checked for secure mode of operation such as maintaining a safe speed or safe position for the drive, comprising the following method steps: determining the position of the drive in both current channels by measuring the three-phase current to the machine, then converting the measured values for the three-phase current to give a current-space vector, calculating the angle of the current-space vector within an electrical revolution and determining the position of the drive (rotor). According to the invention, a current command, whose field acts in the direction of the rotor flow or rotor field is added within the stator (in the direction of the field weakening) which results in a increase in precision of measurement.
