Method for operating an electric machine, device for operating an electric machine, and electric drive system

An electrical drive system comprising:

• an electrical machine (2) having a rotatably mounted rotor and a motor winding, wherein
• the motor winding is electrically connected to an electrical energy store (4) by means of a power electronics (3), and
• a control device (5) configured to
• trigger the power electronics (3) to control the electric machine (2) in a field-oriented manner so that the machine (2) generates a specified desired torque (Ttarget), wherein when it is determined, based on a current actual working point (AP1) of the electric machine (2), that a specified desired working point (AP2) of the electric machine (2) should be set in a time-optimized manner, set the desired working point (AP2) by triggering the power electronics (3) according to a predicted pilot control action, wherein the predicted pilot control action is specified in response to determining that the specified desired working point (AP2) of the electric machine (2) should be set in a time-optimized manner, and wherein the predicted pilot control action includes a plurality of desired voltage vectors, and
• suspend field-oriented control of the electric machine (2) in response to determining that when the desired working point (AP2) should be set in the a time-optimized manner.
