METHOD FOR OPERATING A POSITION-SENSOR-FREE BLDC MOTOR OF AN OIL PUMP, COMPUTER PROGRAM, COMPUTER PROGRAM PRODUCT, HEAT-TRANSFER-MEDIUM SYSTEM, AND VEHICLE
A method for operating a position-sensor-free BLDC motor of an oil pump (19) is proposed. During start-up and a run-up of the oil pump (19), the BLDC motor is operated with feedforward-controlled excitation in order to heat an oil conveyed by the oil pump (19), until the oil has a kinematic viscosity which allows closed-loop-controlled operation of the BLDC motor above a motor-specific limit rotational speed of a rotor of the BLDC motor. Waste heat produced by the BLDC motor as a result of the feedforward control is radiated to the oil in the surroundings of the oil pump (19). Said feedforward control is temporarily interrupted in order to sense a voltage induced by the rotor in the unexcited coils of a stator of the BLDC motor. Above the limit rotational speed of the rotor, a rotor position and a rotor (angular) velocity can be determined with sufficient accuracy by means of said voltage. Above said limit rotational speed, after it has been sensed that said limit rotational speed has been exceeded, a switchover to operation of the BLDC motor with closed-loop-controlled excitation is made. A computer program, a computer program product, a heat-transfer-medium system and a vehicle are also proposed.
