MOTOR CONTROL DEVICE AND ELECTRIC PUMP UNIT |
摘要 |
A control unit includes an excessive output suppression control unit which suppresses an excessive output by reducing a current command value from a host control apparatus. A control signal output unit obtains a motor control signal by adding a reduction amount of the current command value to the current command value. The excessive output suppression control unit includes: an oil pressure estimating unit which estimates oil pressure based on a current and a rotating speed of the electric motor; and a current command value correction amount calculating unit which compares outputs the reduction amount of the current command value if the estimated oil pressure is higher than target oil pressure. One of the target oil pressure and the estimated oil pressure compared by the current command value correction amount calculating unit is corrected based on oil temperature information. |
