Method for operating an electrical machine |
| abstract |
The invention relates to a method for operating an electric machine (2). According to the invention, a direction of rotation of the electric machine (2) is determined, in particular for carrying out an emergency operation in the event of a failure of a speed sensor, via a phase sequence when introducing sinusoidal phase alternating currents, a sign of a torque (M) of the electric machine (2) is determined by a power calculation, and an amount of the torque (M) is limited to a requested torque by an MPTA line. |
