Publication number: 20170163185Abstract: A method for sensorless commutation of a BLDC motor is presented, wherein the following steps are executed.In step 1, the voltage of a currentless phase is sampled in predetermined time intervals. In step 2, the voltage of the zero crossing, and the associated rotational rate, is determined on the basis of the time difference between two sampling points, and the point in time of the zero crossing is supplied to a commutation timer K, when a zero crossing has been detected between two sampling points. In step 3, the time until a predefined angular rotation of the motor is calculated on the basis of the determined rotational rate, and this time is transmitted to the commutation timer. In step 4, the commutation is initiated and the commutation time is reset when the time transmitted to the commutation time has elapsed.Type: ApplicationFiled: December 7, 2016Publication date: June 8, 2017Applicant: ZF Friedrichshafen AGInventors: Holger GOHMERT, Igor JANTZEN, Andreas FÜßL, Thomas HODRIUS
