摘要
The invention relates to a method for determining current setpoints (I qsoll , I dsoll ) for generating a desired motor setpoint torque (M son ) on a permanent magnet-excited electric motor , whereby a current operating point (3) and the desired motor target torque (M should ) are obtained by means of a control device (2), a coefficient (K pm ) for a permanent flux torque component is determined as a function of the operating point a permanent flux torque (M pm ) and a reluctance torque (M reluctance ) can be determined, based on the determined permanent flux torque (M pm ) a torque-generating current setpoint (I qsoll ) is determined, based on the determined reluctance torque (M reluctance ) a magnetic field-weakening current setpoint (I dsoll ) is determined, and the determined current target values (I qsoll , I dsoll ) are provided for regulation. The invention also relates to an associated device (1).
