Machine comprising a plurality of controllable electrical drives and registration and storage of the power and energy values, consisting of - a mechanism - a plurality of a.c. motors for driving the mechanism - at least one rectifier unit, by means of which a direct current voltage U dc is generated from the mains voltage U mains - an inverter in each case, by means of which a three-phase current I mot is taken from the rectifier unit for supplying an a.c. motor in each case - a control module for actuating the associated inverter, which i. detects the current value of the current I mot in at least one phase of the a.c. motor ii. detects the current value of the d.c voltage U dc iii. determines the current value of a power P mot el, which is taken from the a.c. motor and an electrical power W mot, which is consumed in a particular time period, and iv. loads them in a drive data-storage characterised in that - at least one a.c. motor is a permanently excited synchronous motor - a rotating electrical encoder is connected to the shaft of the synchronous motor or to a part of the mechanism that is driven thereby - the control module derives an angular velocity ω mot either by evaluating the signal of the encoder or alternatively from a rotational speed setpoint value - the controller module computes a mechanical power P mech, which is output or consumed by the synchronous motor, from, in each case, the values of the current I mot, the angular velocity ω mot and a torque constant kT of the synchronous motor - the values in each case for P mech are saved in a drive data storage, which is assigned in each case, and calculated and stored with respect to a particular time period and to a consumed or output energy W mech - the values for P mech and W mech are retrieved from a centralized power registration point and evaluated, the power registration point also registering and monitoring a power demand of heating and cooling systems that are intrinsic to the machine. - a mechanism - a plurality of a.c. motors for driving the mechanism - at least one rectifier unit, by means of which a direct current voltage U dc is generated from the mains voltage U mains - an inverter in each case, by means of which a three-phase current I mot is taken from the rectifier unit for supplying an a.c. motor in each case - a control module for actuating the associated inverter, which i. detects the current value of the current I mot in at least one phase of the a.c. motor ii. detects the current value of the d.c voltage U dc iii. determines the current value of a power P mot el, which is taken from the a.c. motor and an electrical power W mot, which is consumed in a particular time period, and iv. loads them in a drive data-storage i. detects the current value of the current I mot in at least one phase of the a.c. motor ii. detects the current value of the d.c voltage U dc iii. determines the current value of a power P mot el, which is taken from the a.c. motor and an electrical power W mot, which is consumed in a particular time period, and iv. loads them in a drive data-storage - at least one a.c. motor is a permanently excited synchronous motor - a rotating electrical encoder is connected to the shaft of the synchronous motor or to a part of the mechanism that is driven thereby - the control module derives an angular velocity ω mot either by evaluating the signal of the encoder or alternatively from a rotational speed setpoint value - the controller module computes a mechanical power P mech, which is output or consumed by the synchronous motor, from, in each case, the values of the current I mot, the angular velocity ω mot and a torque constant kT of the synchronous motor - the values in each case for P mech are saved in a drive data storage, which is assigned in each case, and calculated and stored with respect to a particular time period and to a consumed or output energy W mech - the values for P mech and W mech are retrieved from a centralized power registration point and evaluated, the power registration point also registering and monitoring a power demand of heating and cooling systems that are intrinsic to the machine.
