モータートルク定数が較正される電子整流電気モーター
Document Type and Number:
Japanese Patent JP2013509147
Kind Code:
A
Abstract:
The invention relates to an electrically commutated electrical motor having a stator and having an in particular permanent-magnetically designed rotor. The electronically commutated electrical motor also has a control unit which is connected to the stator and designed to actuate the stator for generating a magnetic rotary field. The control unit is designed to detect a voltage induced in at least one stator coil of the stator and to determine a motor torque constant representing an achievable torque in dependence on a rotational speed signal representing a rotor circumferential frequency of the rotor. According to the invention, the control unit in the electronically commutated electrical motor of the aforementioned type is designed to detect a frequency content of the motor torque constant and to actuate the stator for generating a torque in dependence of the frequency content, in particular a frequency amplitude of the motor torque constant.
