    Abstract: A method for controlling a brushless DC motor (BLDC motor) having a rotor, a stator and an angle sensor and a logic circuit for generating the phase voltages of the windings depending on the phase angle of the rotor. The logic circuit access a lookup table, in which to implement commutation with block-shaped, trapezoidal, sinusoidal, sinoid-based signal waveforms. The drive values are stored for the electrical phase angle of the rotor for generating phase voltages (VU, VV, VW) for the windings. A control unit generates configuration data for the logic circuit determine the commutation form, and depending on the form, the drive values are supplied to a PWM generator for generating control signals (VU, VV, VW) depending on the electrical phase angle of the rotor angle, which PWM control signals can be used to control the phase currents in the windings.
