| 20100028165 | OIL-FLOODED SCREW COMPRESSOR, MOTOR DRIVE SYSTEM, AND MOTOR CONTROL DEVICE - When an oil-flooded screw compressor is started up in a cold environment after a long halt, start-up torque increases due to the increased viscosity of the oil that has long stayed inside the working chambers of the compressor.
