A method for operating an electrically commutated machine. In at least one method step, in particular in at least one method step of overmodulation operation of the electrically commutated machine, a precommutation angle of the electrically commutated machine is set depending on an efficiency of the electrically commutated machine.

Method for operating an electrically commutated machine

The invention relates to a method for operating an electronically commutated electric motor (), in which method, during ongoing operation of the electric motor (), in order to achieve an optimal operating point of the electric motor (), a pre-commutation angle () provided by a control device () is regulated. According to the invention, during an operation of the electric motor (), a period signal () is modulated to the pre-commutation angle () and a state parameter () of the electric motor () correlating with an efficiency of the electric motor () is detected.

Method for operating an electronically commutated electric motor

A winding support () for an electric machine (), having multiple pole teeth (), wherein each pole tooth () has a tooth shank () around which at least one winding can be arranged, and wherein a tooth shank () has an increasing width of the tooth shank () in an axial direction () of the winding support () proceeding from an axial face side of the winding support (). At least one tooth shank () has an increasing or decreasing width in or counter to the radial direction () of the winding support ().
