Method for Operating a Position Sensorless BLDC Motor of an Oil Pump, Computer Program, Computer Program Product, Heat-Transfer Medium System, and Vehicle
A method for operating a position-sensorless BLDC motor of an oil pump (19) is proposed. When the oil pump (19) is put into operation and run up to speed, to warm an oil that is transported by the oil pump (19), the BLDC motor is operated in a pre-controlled-excited mode until the oil has a kinematic viscosity that allows the BLDC motor to be operated in a controlled mode above a motor-specific limiting speed of a rotor of the BLDC motor. Waste heat of the BLDC motor generated by the pre-control is in this case dissipated to the oil in the surrounding area of the oil pump (19).
