A motor control device performing vector control for a motor that drives a load whose load torque varies periodically. The motor control device has: a motor speed deriving portion estimating or detecting a motor speed; a speed controller producing a specified torque current value such that the motor speed is made to follow a specified motor speed value fed from outside; a resonance filter producing a corrected torque current value by receiving a control value that varies with variations in the load torque and emphasizing a periodic variation component of the control value; a torque current corrector producing a specified superimposed torque current value by superimposing the corrected torque current value on the specified torque current value; and an adjusting portion adjusting, based on the specified superimposed torque current value, the phase of the corrected torque value by controlling the resonance filter. The vector control is performed according to the specified superimposed torque current value.

| 84 | FLUID DISPLACEMENT PUMP WITH BACKPRESSURE STOP | EP02728628.5 | 2002-03-28 | EP1421282B1 | 2007-11-07 | Vanmoor, Arthur |
| The fluid displacement pump enables substantially continuous pumping from a low-pressure side to a high-pressure side substantially without any backflow or backpressure pulsations. Liquid or gas is injected to the high-pressure side by way of mutually intertwined worm spindles that form a fluidtight displacement system. The blades (9A, 9B) of the impeller system are slightly curved from the inside out, i.e., from their axles (31) to their periphery, so as to ensure a tight seal between adjacent blades. The orientation of the blades is almost flat, i.e., their attack angle relative to backpressure is close to perpendicular so that they will turn quite freely in the forward direction, but will not be turned backwards by a pressurized backflow. The impeller rotation that is introduced via the spindle shafts (31) nevertheless leads to a volume displacement towards the high-pressure side, for instance, towards a chamber to be pressurized or to be subjected to equal pressure. | ||||||
| 85 | Scroll machine with continuous capacity modulation | EP06002801.6 | 2001-10-10 | EP1655493A2 | 2006-05-10 | Pham, Hung M. |
An improved continuous capacity modulation system for scroll-type compressors is disclosed in which a valve body of a solenoid valve assembly is secured to the inner wall of the hermetic shell and the actuating coil is mounted on the outer surface thereof. The actuating coil includes a plunger/valve member which cooperates with passages provided in the valve body to selectively actuate the capacity modulation arrangement utilizing compressed fluid. The construction offers the advantage that all fluid pressure lines are located within the hermetic shell and thus protected from potential damage, the solenoid coil may be easily changed/replaced to accommodate different available operating voltages and/or malfunction thereof and the system can be easily tested prior to final welding of the outer shell. The actuating coil is controlled by Pulse Width Modulation to reduce the load demand of the compressor during times when load shedding is required.

The present invention provides a screw compressor for refrigerating apparatus capable of controlling the rotational speed of a motor to be suitable for cooling heat load by simply controlling an inverter, without causing the overload of the motor. The screw compressor 1A for refrigerating apparatus 10A, which uses a motor 22 controlled by an inverter, as a driving portion, is provided with a suction pressure detector D3 as a heat load detecting means for detecting the cooling heat load; a motor coil temperature detector D1 as a means for detecting the load condition of the motor 22; and a controller 26 that decreases the rotational speed of the motor 22 if the capacity of the compressor is determined as excessive based on a pressure signal from the detector D3, maintains the rotational speed if the capacity is determined neither excessive nor lacking. In case that the capacity is determined as lacking, the controller 26 reduces the rotational speed if the load condition is determined as excessive based on a temperature signal from the detector D1 and increases the rotational speed in the other case. |
