2.1 Appropriate application
The linear motors of the types described here are used exclusively to carry out linear movements. The direct
drives are intended for use in industrial plants. The motors are only operated with original LinMot servo
drives. For external temperature monitoring, 2 temperature sensors and a temperature relay are used, which
interrupts the power supply in the event of a fault. The motors are intended for use in potentially explosive
atmospheres which occasionally occur (zone classification 1, 21, 2, 22 according to DIN EN 60079-14).
Explosivity can consist of gases, vapours, mists and dust. The motors are dimensioned for an ambient
temperature of 0 °C to 60 °C. The motors are designed for a temperature range of 0 °C to 50 °C. The user
determines the operating conditions and thus the maximum surface temperature of the device by means of
the specific type of application of the motors. This allows several temperature classes to be assigned. The
ATEX motors used here correspond to temperature class T4 (max. surface temperature = 135 °C) and T6
(max. surface temperature = 85 °C) according to DIN EN 60079-14. According to this, the devices may be
used in an explosive atmosphere in which the ignition temperature is above the max. surface temperature.
