3 Product description
3.1 Structure
LinMot ATEX linear motors are assembled into a complete servo drive system consisting of several
connected components (see the illustration below).

Pos. 5: Power
3.1.1 Circuit breaker
Interrupts the system power supply if the maximum surface temperature setting is exceeded.
3.1.2 LinMot Servo Drive
Performs position control, temperature monitoring, current regulation, and monitoring of the power supply.
3.1.3 Temperature relay
Receives values from the Kty temperature sensors mounted on the exterior of the motor under the stainless
steel housing. In case of a fault (overtemperature), it initiates the interruption of the power supply to the
servo drive. Feedback to the machine control system.
3.1.4 Linear Motor
LinMot motors are direct-drive electromagnetic tubular linear motors.
The main components of the motor are the stator and the slider. The slider, the so-called "magnet bar",
consists of permanent magnets that are arranged with alternating polarization. The stator contains the
windings and position sensors. The windings are fed with current at an appropriate electrical phase angle,
like a permanently excited synchronous motor, thus producing a force in the desired direction. The motor has
3 (or 4) temperature sensors on the windings. These sensors can be used with a series x1100 or x1200
LinMot drive to read and analyze the absolute temperature. This makes it possible to determine the winding
