Abstract
An electromagnetic drive for a cutting device of a textile machine for severing a thread, a cutting device having an electromagnetic drive, and a yarn clearer having a cutting device are provided. The electromagnetic drive may comprise a solenoid and a piston configured to drive a cutting blade carrier. The piston may be guided for linear movement within the solenoid and may be configured to be linearly moved between a rest position and a working position. The electromagnetic drive may comprise an axial air gap between an end face of the piston and a counter face of a component of the solenoid. The component may be stationary relative to the piston and the axial air gap may be varier based on movement of the piston.
