This derived nominal operating speed can be compared with the actual speed of the motor.
The filaments allow an increase in the maximum compressor rotor operating speed thereby increasing the potential performance of the turbine engine.
In the event that a predeterminable or predetermined speed difference between the nominal operating speed and the actual speed is exceeded, the control unit and/or the semiconductor end stages can be switched off.
The process is repeated until the AC induction motor (12) reaches its full operating speed.
The aim is to increase the critical speed of said centrifuge or the operating speed by reducing the mass action of the planetary gear system.
The internal combustion engine has a predetermined nominal rotational speed nnom and a predetermined swept volume VH.
The braking torque applied to the shaft by the brake shoes is gradually increased while the shaft is driven at free-running speed by the tool being calibrated, and the pulsed output of the impulse tool is monitored.
The control is progressively carried out according to a determined closing instruction via a calibration by using data representative for the engine speed and the ambient temperature (T).
