A current detection value detected by the current sensor (12) and a rotor rotational position are used to estimate three-phase motor current values. The estimated motor current values are used to control the inverter 1).
Thereby, an inexpensive, space-saving AC motor driving apparatus as well as an AC motor controller, electric actuator, or vehicle that can perform highly precise torque control from zero speed to high-speed rotation without depending on the PWM pulse pattern are provided.

摘要： In a vacuum cleaner, both static pressure H data and a variation width ΔH in the static pressure appearing when a suction port is operated are detected from a pressure sensor (8) provided at a rear side of a filter (7) within a main body (2) of the vacuum cleaner; a current variation width Δpbi appearing when the suction port is operated is detected from a current of a nozzel motor (26) for driving a rotary brush (10) stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor (FM) and static pressure ; command values are newly obtained by performing a fuzzy calculation with the variation width Apbi, static-pressure command value Hcmd ; the variation width ΔH and the static-pressure command value Qcmd ; the variation width Δpbi and static-pressure command value Hcmd ; and also the variation width ΔH and static-pressure command value Qcmd as the input thereto ; the rotational speeds of the fan motor (FM) and nozzel motor (26) are controlled from the result of the command values ; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.

摘要： A controlling apparatus (10) controls a suction performance of a blower motor (2) which is installed into a main body (3) of a cleaner (1). The controlling apparatus (10) increases the suction performance when a suction nozzle is operated and decreases the suction performance when the suction nozzle is stopped. Corresponding to a floor cleaning suction nozzle and a crevice cleaning suction nozzle, at a predetermined air flow amount range, the most suitable operation control is carried out automatically in accordance with the detected kind of suction nozzle. Whe the suction nozzle is exchanged the flow amount range is changed over and selected in accordance with the respective suction nozzle. A brushless direct motor is used as the blower motor and has an operational range by means of chopper control duty factor of 100 %.

摘要： In an apparatus using an inverter as a motor drive apparatus (10), continuous operation can be permitted during a motor open-phase without providing any additional switching element. Especially, in an electric brake apparatus (30), higher security can be assured. When a motor winding (LU, LV, LW) of one phase occurs an open-phase, currents are conducted to the remaining normal phases while taking the position of a rotor (101) of motor (20) into account to thereby generate torque of the motor (20). Since the motor torque can be generated continuously in the event of a phase malfunction, reliability of apparatus such as the electric brake apparatus (30) can be improved.
