An electromagnetic clutch (1), in particular for an air-conditioning compressor (2) of a motor vehicle (11), transmits torque to a drive shaft (3) of the compressor (2) as a function of a current (I) fed to a clutch coil (4) of the electromagnetic clutch (1) to generate an electromagnetic clutch force. According to the control method (10), the slip of the electromagnetic clutch (1) is determined from the difference between the rpm of the electromagnetic clutch (1) and the rpm of the drive shaft (3) and is monitored by a slip sensor (5). The current (I) and the generated clutch force are adjusted by a pulse width modulation controller (6) of the compressor (2) as a function of the slip. A pulse width modulation controller (6) is electrically connected to the clutch coil (4) and modulates the pulse width of the current (I) fed to the clutch coil (4).

    一种特别地用于机动车辆(11)的空调压缩机(2)的电磁离合器(1),该电磁离合器根据馈送到电磁离合器(1)的离合器线圈(4)以产生电磁离合力的电流(I)将扭矩传递到压缩机(2)的驱动轴(3)。根据控制方法(10),电磁离合器(1)的滑移由电磁离合器(1)的rpm与驱动轴(3)的rpm之间的差来确定,并由滑移传感器(5)监测。通过压缩机(2)的脉宽调制控制器(6)根据该滑移来调节电流(I)和产生的离合力。脉宽调制控制器(6)电连接到离合器线圈(4)并调制馈送到离合器线圈(4)的电流(I)的脉宽。
