The invention relates to a tape winder unit, comprising a housing (10), a tape coil (20) rotatably mounted in the housing (10), a locking unit for locking the tape coil on the housing, the locking unit having an actuator unit (40) with an electromagnet (42), and a control device (50) for actuating the electromagnet (42), which control device has a power supply input (55), the invention relates to a control device (50) for a motor vehicle, comprising an electromagnet (42), a power supply output (56) connected to the electromagnet (42), and at least one signal input (57) for receiving a control signal and/or a sensor unit (52) for generating a control signal, the control device (50) having at least one first active switching state in which the control device (50) is electrically connected to the electromagnet (42), and a passive switching state in which the control device (50) is electrically connected to the electromagnet (42). A current flows between the power supply output (56) and the electromagnet (42), the current intensity of which is greater than the current in the passive switching state, and wherein the control device (50) has at least one DC-DC converter (60) as a constant current source between the power supply input and the power supply output, the current intensity in the first active switching state has a defined first value (I1) independent of the voltage applied to the power supply input.

    本发明涉及一种带式卷绕器单元,带有壳体(10),可旋转地支承在壳体(10)中的带式线圈(20),用于将带式线圈闭锁在壳体上的闭锁单元,其中,闭锁单元具有带有电磁铁(42)的致动器单元(40),以及用于操控电磁铁(42)的控制装置(50),其具有电源输入(55),连接到电磁铁(42)的电源输出(56),以及用于接收控制信号的至少一个信号输入(57)和/或用于产生控制信号的传感器单元(52),其中,控制装置(50)具有至少一个第一有源开关状态和一个无源开关状态,其中,在第一有源开关状态下,电流在电源输出(56)和电磁铁(42)之间流动,其电流强度大于无源开关状态下的电流,其中,控制装置(50)在电源输入和电源输出之间具有至少一个作为恒流源的直流‑直流转换器(60),使得在第一有源开关状态下的电流强度具有与施加在电源输入上的电压无关的定义的第一值(I1)。
