Abstract

An EC motor (1), comprising: motor electronics, a signal input or signal output, and an optocoupler (5 ); its purpose is to reliably determine the degradation of the optocoupler (5) and improve the service life of the EC motor (1). This object is achieved in that when the optocoupler (5) is connected, the evaluation unit (6) periodically evaluates the saturation voltage of the optocoupler (5) at its output relative to a reference threshold, and when the saturation voltage exceeds the reference threshold An early warning signal is generated when the threshold is reached.

Description

technical field [0001] The invention relates to an EC motor comprising motor electronics, a signal input or signal output, and an optocoupler for electrically isolated transmission of useful signals between a motor control unit and the signal input or signal output . Background technique [0002] In EC motors, optocouplers are used to electrically isolate and transmit signals useful for open-loop, closed-loop or monitoring functions. Electrical isolation is used to protect individuals and materials, in particular to isolate the sensitive open-loop control electronics to which the EC motor is connected, from the motor electronics of the EC motor. Inexpensive optocouplers with a simple and inexpensive integrated circuit structure inside are especially used in EC motors for products with a large number of parts. These inexpensive variants of optocouplers consist of a light transmitter, usually a light-emitting diode (LED), and a light receiver, specifically a phototransistor....
