摘要： A control circuit for a reluctance machine having two mutually movable parts and at least one inductive phase winding adapted for a certain maximum drive current value. The method includes detecting when a phase winding is in a non-drive mode; causing a test current, having a second maximum value lower than said certain maximum value, to flow through the phase winding and through a current sensor when the winding is in the non-drive mode; and establishing a mutual position in dependence of the output of said current sensor.

摘要： A control device for electric motors and a method for monitoring the serviceability of a transmission part arranged for transmission of torque between an electric motor and a load during operation. The method comprises the steps of initiating at least one test sequence, and sending a signal indicating an error if said at least one test sequence indicates that the serviceability of the transmission part is not acceptable and if no further test sequences are to be performed. Additionally, said at least one test sequence includes the steps of setting a rotation speed of the electric motor at a test rotation speed, which differs from the rotation speed of the electric motor immediately prior to said setting, and measuring at the electric motor, within a period starting from the setting of the rotation speed of the motor and ending when the rotation speed of the electric motor has reached the test rotation speed.
摘要翻译：一种用于电动机的控制装置和用于监测在运行期间布置成在电动机和负载之间传递转矩的变速器部分的适用性的方法。所述方法包括以下步骤：启动至少一个测试序列;以及如果所述至少一个测试序列指示所述传输部分的可服务性不可接受并且如果不执行其它测试序列，则发送指示错误的信号。此外，所述至少一个测试顺序包括以下步骤：将电动机的转速设定在与所述设定之前的电动马达的转速不同的测试转速，以及在电动机的内部测量从电动机的转速的设定开始的期间，并且当电动机的转速达到测试转速时结束。
