Title:

MOTOR CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2012/144276

Kind Code:

A1

Abstract:

Proposed is a motor control device that executes rotary control that tracks load fluctuations in a starting motor. The proposed motor control device is provided with: a detection means (4) that detects the current wave height (Ip) and the current electrical angle (θi) on the basis of phase currents (Iu-Iw); a detection means (5) that detects the induced voltage wave height (Ep) and the induced voltage electrical angle (θe) on the basis of the phase currents (Iu-I2) and the imposed voltages (Vu-Vw); a rotor position detection means (6) that detects the rotor position (θm) using θm = θi - β - 90° or θm = θe - γ - 90°; a velocity fluctuation detection means (15) that detects the rotational velocity (ω) on the basis of θm; and a startup means (10) that outputs the voltage indicated value (Vp) for startup and the voltage phase indicated value (θv) for startup, increases the rotational velocity of a synchronization motor (M) by a predetermined acceleration, and causes the rotational velocity (ω) output by the velocity fluctuation detection means (15) to be reflected in θv.
