As a specialist for special servomotors, Servotecnica also supplies actuators for use in potentially explosive environments in the product portfolio: the 600 W strong, brushless Servomotors of the SVTM 80B3X-Ex series are certified to Atex II 2G Ex d IIB T4 Gb, approved to EN60079-0, EN60079-1 and tested to EN 60034-18-41.
As such, the brushless servomotors may be operated in areas with potentially explosive dust and gas atmospheres. Atex motors guarantee the required high level of safety when used in Ex zones 1 and 2. With their refractory metal housing, they comply with the temperature class T4 (maximum surface temperature 135 ° C) and the fire resistance class "D" (metallic fires).
The explosion-proof, brushless servomotors feature an IC 400 surface-cooled design. Your fully enclosed engine needs no additional ventilation. In order to achieve a longer service life, insulating materials of the insulation class up to 200 ° C were used almost exclusively, all of which are UL-certified. The special stator packing with winding in the slot and the use of neodymium magnets guarantee a high power density of the compact Atex motors and result in a sinusoidal source voltage. For increased safety, temperature sensors provide each motor winding. They protect against overheating and thus increase the life of the motor. The motors were tested in accordance with EN 60034-18-41 for partial discharges between the coils.
