摘要： The controller for an actuator that is driven by a brushless motor estimates the temperature of the magnet in the brushless motor on the basis of an electric current value and a rotation speed thereof which are obtained by supplying power to rotate the brushless motor in a reverse direction, and limits current flowing through the brushless motor during forward rotation so as to prevent the magnet temperature from rising beyond an allowable maximum temperature. Limiting the current flowing through the brushless motor on the basis of the estimated magnet temperature makes it possible to drive the brushless motor while preventing the magnet temperature from rising beyond the allowable maximum temperature without providing the brushless motor with any temperature sensor for detecting the magnet temperature therein.

摘要： A controller for an electric compressor sets a temperature rise region A, a temperature drop region B, and a steady region C from change in temperature of switching elements, and sets a carrier frequency for each of the set regions. In the region A, the carrier frequency is changed according to the element temperature so that the carrier frequency decreases with increase of the element temperature at startup of a motor. In the region B and the region C, the carrier frequency is changed according to the number of revolutions of a compression mechanism, so that the carrier frequency decreases with increase of the number of revolutions of the compression mechanism, regardless of the element temperature.

摘要： An apparatus for protecting a fluid pump motor includes an electric motor for driving a pump head to pressurize a fluid. A liner is positioned in the motor air gap to prevent pressurized fluid from contacting one or more magnetic field producing elements of the stator. The liner includes a thin wall to minimize the air gap distance. The liner wall is made thin enough that, under loading of the pressurized fluid, the liner wall deforms and bears against one or more of the field producing elements of the stator for structural support. The liner is preferably fabricated as a single metal part using a deep drawing process that results in a can having opposed open and closed ends with a substantially uniform cross-section between the open and closed ends of the can.

摘要： A fluid impermeable barrier is provided to protect the rotor of an electric motor. The barrier includes a body portion with a relatively large opening at one end to receive the rotor laminations and a smaller opening at the other end to receive one end of the rotor shaft. With the body portion positioned about the laminations, a cap with an outer perimeter and central opening is slid down the other end of the rotor shaft to close the large opening in the body portion. The assembly is completed by sealingly attaching the outer perimeter of the cap to the large opening in the body portion and sealingly attaching the smaller openings in the cap and body portion to respective portions of the rotor shaft. Thus, the fluid impermeable rotor barrier includes no more than two parts that are assembled onto the rotor using no more than three areas of attachment.

摘要： In a known method for regulating a delivery variable of a pump, which is driven by an electric motor operated with alternating current of variable frequency, especially via a converter, the input power of the motor is measured as the actual value for the delivery variable and is regulated by comparison with a desired value. To avoid the influence of the temperature of the motor on the delivery variable at constant input power, according to the invention upon a change in the temperature in the motor a corresponding compensating variable is taken into account in the control for the purposes of correcting the input power. As an alternative, associated values of the input power and the speed of the motor at a predetermined desired pressure value are determined empirically and stored as a table, and during operation a value of the input power belonging to a measured or approximately calculated speed of the motor is retrieved from the table as desired for regulating the input power.
