Abstract: A method of a hand held torque delivering power tool for tightening a screw joint up to a predetermined target torque level, the method including applying a tightening torque to the screw joint during a tightening phase via a snug torque level, indicating during the tightening phase a torque growth characteristic, interrupting the torque application on the screw joint upon arrival at a target torque level to prevent further rotation of the screw joint, and resuming the torque application via a declination ramp at a declining rate after the target torque level is reached. The resumed torque application is declined at a rate corresponding to the indicated torque growth characteristic to obtain an ergonomically favorable torque reaction characteristic in the power tool.

Abstract: A drive controller for a motor of a compressor includes a drive circuit that applies voltages to windings of the motor. A speed control module controls the drive circuit to rotate the motor at a requested speed. A speed determination module generates the requested speed based on a speed demand from a system controller. A lost rotor control module identifies a lost rotor condition and, in response to identifying the lost rotor condition, instructs the speed determination module to set the requested speed to an override speed that is lower than the speed demand. The lost rotor control module identifies the lost rotor condition in response to a comparison of a speed error with an adaptive threshold. The speed error is based on a difference between requested and estimated speeds of the motor. During first and second system states, the adaptive threshold is set to first and second thresholds, respectively.

Abstract: A drive controller for a motor of a compressor includes a drive circuit that applies voltages to windings of the motor. The drive controller includes a speed control module that controls the drive circuit to rotate the motor at a requested speed. The drive controller includes a speed determination module that generates the requested speed. The drive controller includes a defrost module that enables a defrost mode in response to a defrost command.
